The Genus Sagina (Caryophyllaceae) in Italy: Nomenclatural Remarks

A contribution to the nomenclature of the genus Sagina is presented. The following 10 taxa are recognized as being part of the Italian flora: S. alexandrae, S. apetala, S. glabra, S. maritima, S. micropetala, S. nodosa, S. pilifera, S. procumbens, S. revelierei, and S. saginoides subsp. saginoides. The names S. apetala var. decumbens (=S. apetala subsp. apetala), S. bryoides (=S. procumbens), S. patula (=S. apetala subsp. apetala), S. revelierei, Spergula glabra (=S. glabra), Spergula pilifera (=S. pilifera), and Spergella subulata var. macrocarpa (=S. saginoides subsp. saginoides) are here typified. Specimens deposited at B-W, C, E, and LY, and illustrations by Reichenbach were considered for the typifications. Specifically, two Reichenbach's illustrations are chosen for S. bryoides and S. saginoides var. macrocarpa. A specimen at B-W is designated as the lectotype of S. glabra. Two specimens at C and G are designated as the lectotypes of S. apetala var. decumbens and S. revelierei, respectively. A specimen at LY is designated for S. patula. As we did not find original material, a neotype at G is designated for S. pilifera.

Navigating the Complexities Involving the Identification of Botulinum Neurotoxins (BoNTs) and the Taxonomy of BoNT-Producing Clostridia

Botulinum neurotoxins are a varied group of protein toxins that share similar structures and modes of activity. They include at least seven serotypes and over forty subtypes that are produced by seven different clostridial species. These bacterial species are not limited strictly to BoNT-producers as neuro-toxigenic and non-neuro-toxigenic members have been identified within each species. The nomenclature surrounding these toxins and associated bacteria has been evolving as new isolations and discoveries have arisen, resulting in challenges in diagnostic reporting, epidemiology and food safety studies, and in the application of therapeutic products. An understanding of the intricacies regarding the nomenclature of BoNTs and BoNT-producing clostridia is crucial for communication that allows for accurate reporting of information that is pertinent to each situation.

`Cryo-EM': electron cryomicroscopy, cryo electron microscopy or something else?

Structural biology continues to benefit from an expanding toolkit, which is helping to gain unprecedented insight into the assembly and organization of multi-protein machineries, enzyme mechanisms and ligand/inhibitor binding. During the last ten years, cryoEM has become widely available and has provided a major boost to structure determination of membrane proteins and large multi-protein complexes. Many of the structures have now been made available at resolutions around 2 Å, where fundamental questions regarding enzyme mechanisms can be addressed. Over the years, the abbreviation cryoEM has been understood to stand for different things. We wish the wider community to engage and clarify the definition of cryoEM so that the expanding literature involving cryoEM is unified.

A Generalized Nomenclature Scheme for Graphene Pores, Flakes, and Edges, and an Algorithm for Their Generation and Numbering

In the present study, we generalize our recently proposed nomenclature scheme for porous graphene structures to include graphene flakes and (periodic) edges, i.e., nanographenes and graphene nanoribbons. The proposed nomenclature scheme is a complete scheme that similarly treats all these structures. Beyond this generalization, we study the geometric features of graphene flakes and edges based on ideas from the graph theory, as well as the pore-flake duality. Based on this study, we propose an algorithm for the systematic generation, identification, and numbering of graphene pores, flakes, and edges. The algorithm and the nomenclature scheme can also be used for flakes and edges of similar honeycomb systems.

An annotated nomenclatural checklist of endemic vascular plants distributed in the Ukrainian Carpathians

Background

The current paper presents a nomenclatural checklist for vascular plants validated being (sub)endemic to and present in the flora of the Ukrainian Carpathians. This checklist is a part of the work targeted on an inventory of endemic plants distributed in the Ukrainian Carpathians. It is mainly based on the analysis of primary sources (i.e. original protologues and monographic works), but also uses the data provided in the recent online taxonomic aggregators, such as the Global Biodiversity Information Facility (GBIF), Catalogue of Life (CoL), Plants of the World Online (POWO), Euro+Med PlantBase, World Flora Online (WFO) and others. Over 7,000 specimens deposited in the leading Ukrainian herbaria were also revised and used as a supporting data source during the work on the checklist.

New information

The checklist provides a revised nomenclature, including corrections on publication dates, rediscovered taxonomic protologues, corrected authorships and revised taxonomic status for (sub)endemic (sub)species of vascular plants occurring in the Ukrainian Carpathians. It contains 1,101 names, from which 78 species and subspecies have been accepted as valid and 1023 species and infraspecific taxa are provided as synonyms. It is completed with critical notes on the nomenclature of problematic taxa and brief annotations regarding their distribution in the Ukrainian Carpathians, indicating the endemicity range and sozological status for all analysed (sub)species.The current checklist is linked with the GBIF taxonomic backbone, provides notes on detected issues and primarily focuses on its update and correction of the nomenclatural issues and taxonomic inconsistencies, but also aims at discussing issues in other popular taxonomic databases.Sabulinapauciflora is proposed as a new combination to comply with a recent revision of the genus Sabulina.

Revision of the genus Agrostis (Poaceae, Pooideae, Poeae) in Megamexico

Agrostis is one of the most diverse genera of the Poaceae, including ca. 198 species, principally distributed in cold and temperate regions of the world, but also found in the high mountains of the tropics. We present a revision based on morphoanatomical evidence, for the biogeographic region known as Megamexico 3 (i.e., Mexico including the desert areas of southern USA and the Central America territory, to northern Nicaragua). We include taxonomic descriptions and an identification key for the found taxa, maps with the known geographical distribution of the species, and figures with the morphoanatomical characteristics, elevation and phenology. Agrostis is represented in the study zone by 20 species, of which four are endemic and three are introduced. Most records of the genus are distributed in the mountains, above 1500 m a.s.l., in open areas of temperate forests, with conifers and Quercus. Specimens with spikelets occur year round, but most records occur during the wet season, in the months of July to October. We propose a preliminary conservation assessment for each species in the study zone, according to the International Union for Conservation of Nature categories: one with Deficient Data (DD), six as Endangered (EN), two as Vulnerable (VU), and 11 as Least Concern (LC).

What's in a Name? An Overview of the Proliferating Nomenclature in the Field of Phage Lysins

In the last few years, the volume of research produced on phage lysins has grown spectacularly due to the interest in using them as alternative antimicrobials. As a result, a plethora of naming customs has sprouted among the different research groups devoted to them. While the naming diversity accounts for the vitality of the topic, on too many occasions it also creates some confusion and lack of comparability between different works. This article aims at clarifying the ambiguities found among names referring to phage lysins. We do so by tackling the naming customs historically, framing their original adoption, and employing a semantic classification to facilitate their discussion. We propose a periodization of phage lysin research that begins at the discovery era, in the early 20th century, enriches with a strong molecular biology period, and grows into a current time of markedly applied research. During these different periods, names referring to the general concepts surrounding lysins have been created and adopted, as well as other more specific terms related to their structure and function or, finally, names that have been coined for the antimicrobial application and engineering of phage lysins. Thus, this article means to serve as an invitation to the global lysin community to take action and discuss a widely supported, standardized nomenclature.

Whose Ear?: Proposal to conserve the name Auricularia auricula (L.) Underw. for Auricularia auricula-judae (Bull.) Quél

Auricularia auricula-judae is a saprobic European jelly fungus with traditional culinary and medicinal significance, often said to resemble a human ear. It was originally named Tremella auricula by Linnaeus and has been moved to different genera since, but its specific epithet was also changed from auricula to auricula-judae by Bulliard in 1789, which is not normally a valid nomenclatural alteration. However, due to the practice of "name sanctioning" in the mycological nomenclatural code, this change has been accepted. This article outlines the nomenclatural and cultural history of the controversial name Auricularia auricula-judae and suggests its return to the original specific epithet auricula, as well as the designation of an epitype specimen.

An International Society for Cell and Gene Therapy Mesenchymal Stromal Cells (MSC) Committee perspectives on International Standards Organization/Technical Committee 276 Biobanking Standards for bone marrow-MSCs and umbilical cord tissue-derived MSCs for research purposes

The rapidly growing field of mesenchymal stromal cell (MSC) basic and translational research requires standardization of terminology and functional characterization. The International Standards Organization's (ISO) Technical Committee (TC) on Biotechnology, working with extensive input from the International Society for Cells and Gene Therapy (ISCT), has recently published ISO standardization documents that are focused on biobanking of MSCs from two tissue sources, Wharton's Jelly, MSC(WJ) and Bone Marrow, MSC(M)), for research and development purposes and development. This manuscript explains the path towards the consensus on the following two documents: the Technical Standard ISO/TS 22859 for MSC(WJ) and the full ISO Standard 24651 for MSC(M) biobanking. The ISO standardization documents are aligned with ISCT's MSC committee position and recommendations on nomenclature because there was active input and incorporation of ISCT MSC committee recommendations in the development of these standards. The ISO standardization documents contain both requirements and recommendations for functional characterization of MSC(WJ) and MSC(M) using a matrix of assays. Importantly, the ISO standardization documents have a carefully defined scope and are meant for research use of culture expanded MSC(WJ) and MSC(M). The ISO standardization documents can be updated in a revision process and will be systematically reviewed after 3-5 years as scientific insights grow. They represent international consensus on MSC identity, definition, and characterization; are rigorous in detailing multivariate characterization of MSCs and represent an evolving-but-important first step in standardization of MSC biobanking and characterization for research use and development.

What Is Wrong with Frankenia nodiflora Lam. (Frankeniaceae)? New Insights into the South African Sea-Heaths

The taxonomic identity and phylogenetic relationships of several southern African perennial taxa related to Frankenia repens are discussed. In particular, F. nodiflora Lam., a misunderstood species described from the Cape region and synonymised to F. pulverulenta, is restored for plants endemic to salt-pans and riverbeds in the coastal lowlands across the Cape Flats (Western Cape province, South Africa). Further, a revision of morphologically close plants, usually identified as F. pulverulenta or F. repens, also occurring in similar saline ecosystems of the inland western South Africa revealed the existence of two distinct new entities not matching any described taxa of the genus. Molecular analyses of nuclear ribosomal (ITS1-5.8S-ITS2 region) DNA sequence data together with morphological divergence allow recognition of those taxa at species rank, within an independent lineage close to F. repens. In consequence, two new sea-heath species are described in the so-called "F. repens group": F. nummularia from the Nama-Karoo Biome (Western Cape and Northern Cape provinces), and F. anneliseae from the Succulent Karoo Biome (Northern Cape province). Full morphological description and type designation are reported for each accepted species as well as data on ecology, habitat, distribution, and taxonomic relationships to other close relatives are given. Further, an identification key is presented to facilitate recognition of the southern African taxa of Frankenia.

Pedicularis rostratospicata subsp. marsica (P. Sect. Rostratae, Orobanchaceae), a New Subspecies from the Central Apennines (Italy)

The new subspecies Pedicularis rostratospicata subsp. marsica is here described based on morphological and molecular analyses. The new taxon is endemic to few localities of the Central Apennines within the Abruzzo, Lazio and Molise National Park (Central Italy). Pedicularis rostratospicata subsp. marsica can be distinguished from the other two currently accepted subspecies (subsp. rostratospicata and subsp. helvetica) by their taller stems, shorter petioles of basal and middle leaves, narrower blades of basal leaves, longer inflorescences with longer internodes and more flowers, and longer calyx lobes. Molecular analysis confirmed the autonomy of the new taxon. Furthermore, the conservation status assessment of the new subspecies according to IUCN categories and criteria is proposed and discussed, and an analytical key to the three subspecies of P. rostratospicata is presented.

Rosadavurica var. rubro-stipulata (Rosaceae), the correct name for R.davurica var. alpestris

The name Rosadavuricavar.alpestris (Nakai) Kitag. was published in 1979 as a new combination based on R.rubro-stipullatavar.alpestris Nakai. It is generally accepted as a deciduous shrub occurring in Russia, Manchuria, Japan, and the northern part of the Korean Peninsula and is distinguished by the presence of eglandular leaves. Rosarubro-stipullatavar.alpestris was originally described as a new variety with a leaf size relatively smaller than that of R.rubro-stipullatavar.rubro-stipullata . However, the observation of various specimens showed the leaf size of var.alpestris to be of minor importance, and it was included in var.rubro-stipullata as a synonym. Due to the priority of autonyms, a new combination is required to replace R.davuricavar.alpestris. Additionally, it should be noted that the epithet "rubro-stipullata" is derived from the Latin word "stipula" rather than "stipulla." Therefore, for this variety, we propose a new combination, R.davuricavar.rubro-stipulata (Nakai) D. C. Son & Y. S. Kim, comb. nov. & stat. nov.

Typification and Nomenclature Notes on Twenty-Nine Names in Asparagus (Asparagaceae)

Nomenclatural types for twenty-nine names belonging to the genus Asparagus are typified and discussed. The following names are lectotypified: A. altiscandens Engl. & Gilg, A. altissimus Munby, A. baumii Engl. & Gilg, A. benguellensis Baker, A. burchellii Baker, A. curillus Buch.-Ham. ex Roxb., A. deflexus Baker, A. duchesnei L.Linden, A. equisetoides Welw. ex Baker, A. fasciculatus Thunb., A. griffithii, Baker, A. homblei De Wild., A. kaessneri De Wild., A. lecardii De Wild., A. longicladus N.E.Br., A. longiflorus Franch., A. monophyllus Baker, A. palaestinus Baker, A. pastorianus Webb & Berthel., A. persicus Baker, A. poissonii H.Perrier, A. psilurus Welw. ex Baker, A. ritschardii De Wild., A. sapinii De Wild., A. scandens Thunb., A. schumanianus Schltr. ex H.Perrier, A. stellatus Baker, A. subfalcatus De Wild., and A. undulatus (L.f.) Thunb. (synonym of Dracaena undulata L.f.). A new name, Asparagus neofasciculatus, is proposed as a replacement name for A. fasciculatus Thunb., which is an illegitimate later homonym of A. fasciculatus R.Br. The original protologue of these names and the original materials are evaluated. Nomenclature remarks discussing the selection of type specimens are given for each name, and known isotypes or isolectotypes are also cited. This information could be utilized as a reference for future taxonomic and systematic studies on Asparagus around the world.

[Dementia: Overview of Nomenclature and the Most Common Forms]

This article explains the nomenclature of dementia in common use and presents a brief overview of the typical symptoms and findings of the most common forms of dementia. A particular focus is placed on Lewy body dementia, which is often underdiagnosed.

Combining Congenital Heart Surgical and Interventional Cardiology Outcome Data in a Single Database: The Development of a Patient-Centered Collaboration of the European Congenital Heart Surgeons Association (ECHSA) and the Association for European Paediatric and Congenital Cardiology (AEPC)

The European Congenital Heart Surgeons Association (ECHSA) Congenital Database (CD) is the second largest clinical pediatric and congenital cardiac surgical database in the world and the largest in Europe, where various smaller national or regional databases exist. Despite the dramatic increase in interventional cardiology procedures over recent years, only scattered national or regional databases of such procedures exist in Europe. Most importantly, no congenital cardiac database exists in the world that seamlessly combines both surgical and interventional cardiology data on an international level; therefore, the outcomes of surgical and interventional procedures performed on the same or similar patients cannot easily be tracked, assessed, and analyzed. In order to fill this important gap in our capability to gather and analyze information on our common patients, ECHSA and The Association for European Paediatric and Congenital Cardiology (AEPC) have embarked on a collaborative effort to expand the ECHSA-CD with a new module designed to capture data about interventional cardiology procedures. The purpose of this manuscript is to describe the concept, the structure, and the function of the new AEPC Interventional Cardiology Part of the ECHSA-CD, as well as the potentially valuable synergies provided by the shared interventional and surgical analyses of outcomes of patients. The new AEPC Interventional Cardiology Part of the ECHSA-CD will allow centers to have access to robust surgical and transcatheter outcome data from their own center, as well as robust national and international aggregate outcome data for benchmarking. Each contributing center or department will have access to their own data, as well as aggregate data from the AEPC Interventional Cardiology Part of the ECHSA-CD. The new AEPC Interventional Cardiology Part of the ECHSA-CD will allow cardiology centers to have access to aggregate cardiology data, just as surgical centers already have access to aggregate surgical data. Comparison of surgical and catheter interventional outcomes could potentially strengthen decision processes. A study of the wealth of information collected in the database could potentially also contribute toward improved early and late survival, as well as enhanced quality of life of patients with pediatric and/or congenital heart disease treated with surgery and interventional cardiac catheterization across Europe and the world.

A hitherto overlooked article by Gressitt in 1941 (Insecta, Coleoptera, Cerambycidae, Lamiinae)

An article published by Gressitt (1941) has been ignored by all longicornists, including Gressitt himself. However, according to ICZN, it meets all criteria as an official publication, and this status affects three taxa that were formally described therein: Bacchisa (Bacchisa) rigida (Gressitt, 1941) = Chreonomarigida Gressitt, 1941 = Chreonomarigida Gressitt, 1942 homonym and syn. nov.; Tetraophthalmussikang (Gressitt, 1941) = Chreonomasikang Gressitt, 1941 = Chreonomasikanga Gressitt, 1942, syn. nov.; Anastathesparvahainana Gressitt, 1941 = Anastathesparvahainana Gressitt, 1942, homonym and syn. nov.

Multigene phylogeny of the order Physarales (Myxomycetes, Amoebozoa): shedding light on the dark-spored clade

The class Myxomycetes consists of free-living protists characterised by their complex life cycle, which includes both microscopic (amoebae, flagellates and cists) and macroscopic stages (spore-bearing fruiting bodies, sclerotia, and plasmodia). Within it, the order Physarales, with more than 450 recognised species, constitutes the largest group. Although previous studies have shown the polyphyly of some of the traditionally accepted genera, its internal phylogenetic relationships have remained uncertain so far, and together with the lack of data for some key species, it prevented any taxonomic and nomenclatural revisions. We have compiled a substantially expanded dataset in terms of both taxon sampling and molecular data, including most of the genera described to date and four unlinked DNA regions, for which we provide partial sequences: nSSU, EF-1α, α-Tub, and mtSSU, analysed through maximum likelihood and Bayesian methods. Our results confirm that the family Didymiaceae is paraphyletic to the rest of Physarales. Within Didymiaceae s.lat., the recent reinstatement of the genus Polyschismium for most species traditionally ascribed to Lepidoderma, except for the type (Ronikier et al. 2022), is further supported here, as well as the definite inclusion of the genus Mucilago in Didymium and Lepidoderma s.str. (L. tigrinum) in Diderma (Prikhodko et al. 2023). Additionally, the genus Diachea is redefined to include some species previously treated in Physaraceae (Craterium spp. with true columella). Within the monophyletic family Physaraceae, most genera are recovered as polyphyletic, suggesting that they should be no longer accepted as currently defined. However, the lack of resolution of some relationships within Physaraceae prevents us from resuscitating or creating several new genera to mitigate polyphyly. Among the well-defined groups with clear molecular signatures, we propose two taxonomic and nomenclatural changes at generic level: 1) a new genus, Nannengaella, is proposed for a major clade containing Physarum globuliferum and other species with heavily calcified sporophores and, often, a true calcareous columella; 2) Lignydium is resurrected for the clade containing Fuligo muscorum. Additionally, Trichamphora is suggested as the correct name for the clade containing Physarum pezizoideum. The taxonomy and nomenclature of some provisional genera, currently synonymous with Fuligo and Physarum, are disentangled, and we provide a comprehensive and updated nomenclatural conspectus that can be used when better resolved phylogenies are obtained. In total, 22 new combinations are proposed in different genera. A provisional key to the genera of the order is also provided. Citation: García-Martín JM, Zamora JC, Lado C. 2023.

Typification of the name Ranunculusrionii (Ranunculaceae)

Available information on the typification of the name Ranunculusrionii in the literature is scarce and misleading. Previously claimed type collections indicate Lagger as the collector, but the protologue discusses only the specimens collected by Rion. Original material for the name is identified, the locality of the type collection is specified, Lagger's way of writing herbarium labels for his type specimens is described, the history of the discovery of R.rionii is reviewed, and the name is lectotypified.

Harmonising nomenclature in pharmacopeial texts

Nomenclature has always been a source of debate in the scientific literature. In the context of pharmaceutical regulation, varying interpretations of technical language can emerge due to philosophical or linguistic differences between two expert groups, which may undo efforts to harmonise regulatory approval mechanisms for new medicines. This letter describes three examples of divergence within pharmacopeial texts produced in the US, EU and Japan and suggests how these have emerged. Ultimately, I advocate for a consensus and an all agreed upon terminology that would be helpful for the global pharmaceutical industry, as opposed to many agreements between individual manufacturers and regulators of medicines, which may reintroduce variation in regulatory standards.

Nomenclature and typification in Verbascum (Scrophulariaceae) from North Africa

The progress of taxonomic work on native Verbascum L. taxa found in Morocco led to a search for reference specimens in various herbaria. This process was extended to the taxa found in the other four countries of North Africa (Algeria, Tunisia, Libya, and Egypt), which make up the southern shore of the Mediterranean basin. Numerous names were identified as needing typification or requiring corrections of their earlier lectotypifications in order to stabilize their nomenclature and provide a better definition of each taxon. As a result, lectotypes are now designated for 35 names, a neotype is proposed for V.ballii (Batt.) Hub.-Mor., and second-step lectotypes are proposed for V.faureisubsp.acanthifolium (Pau) Benedí & J.M.Monts. and V.pinnatisectum (Batt.) Benedí. Comments have been added for each typified name. Known isolectotypes are also mentioned whenever possible. Furthermore, some new combinations are proposed in this paper, namely V.longirostrevar.antiatlantica (Emb.) Khamar, comb. nov., V.longirostrevar.atlantica (Maire) Khamar, comb. nov., and V.longirostrevar.hoggarica (Maire) Khamar, comb. nov.

Classification and Antigen Molecules of Autoimmune Bullous Diseases

Autoimmune bullous diseases (AIBDs), which are a group of tissue-specific autoimmune diseases of the skin, present with various blistering lesions on the skin and mucous membranes, and show autoantibodies of IgG, IgA and IgM against epidermal cell surfaces and basement membrane zone. To date, AIBDs have been classified into a number of distinct subtypes by clinical and histopathological findings, and immunological characteristics. In addition, various biochemical and molecular biological studies have identified various novel autoantigens in AIBDs, which has resulted in proposals of new subtypes of AIBDs. In this article, we summarized various distinct AIBDs, and proposed the latest and most comprehensive classification of AIBDs with their autoantigen molecules.

A SNOMED CT Mapping Guideline for the Local Terms Used to Document Clinical Findings and Procedures in Electronic Medical Records in South Korea: Methodological Study

BACKGROUND

South Korea joined SNOMED International as the 39th member country. To ensure semantic interoperability, South Korea introduced SNOMED CT (Systemized Nomenclature of Medicine-Clinical Terms) in 2020. However, there is no methodology to map local Korean terms to SNOMED CT. Instead, this is performed sporadically and independently at each local medical institution. The quality of the mapping, therefore, cannot be guaranteed.

OBJECTIVE

This study aimed to develop and introduce a guideline to map local Korean terms to the SNOMED CT used to document clinical findings and procedures in electronic health records at health care institutions in South Korea.

METHODS

The guidelines were developed from December 2020 to December 2022. An extensive literature review was conducted. The overall structures and contents of the guidelines with diverse use cases were developed by referencing the existing SNOMED CT mapping guidelines, previous studies related to SNOMED CT mapping, and the experiences of the committee members. The developed guidelines were validated by a guideline review panel.

RESULTS

The SNOMED CT mapping guidelines developed in this study recommended the following 9 steps: define the purpose and scope of the map, extract terms, preprocess source terms, preprocess source terms using clinical context, select a search term, use search strategies to find SNOMED CT concepts using a browser, classify mapping correlations, validate the map, and build the final map format.

CONCLUSIONS

The guidelines developed in this study can support the standardized mapping of local Korean terms into SNOMED CT. Mapping specialists can use this guideline to improve the mapping quality performed at individual local medical institutions.

How, not if, is the question mycologists should be asking about DNA-based typification

Fungal metabarcoding of substrates such as soil, wood, and water is uncovering an unprecedented number of fungal species that do not seem to produce tangible morphological structures and that defy our best attempts at cultivation, thus falling outside the scope of the International Code of Nomenclature for algae, fungi, and plants. The present study uses the new, ninth release of the species hypotheses of the UNITE database to show that species discovery through environmental sequencing vastly outpaces traditional, Sanger sequencing-based efforts in a strongly increasing trend over the last five years. Our findings challenge the present stance of some in the mycological community - that the current situation is satisfactory and that no change is needed to "the code" - and suggest that we should be discussing not whether to allow DNA-based descriptions (typifications) of species and by extension higher ranks of fungi, but what the precise requirements for such DNA-based typifications should be. We submit a tentative list of such criteria for further discussion. The present authors hope for a revitalized and deepened discussion on DNA-based typification, because to us it seems harmful and counter-productive to intentionally deny the overwhelming majority of extant fungi a formal standing under the International Code of Nomenclature for algae, fungi, and plants.

Taxonomic status and nomenclature of Cephalotaxuslanceolata (Cephalotaxaceae)

The nomenclature of Cephalotaxuslanceolata is controversial. After a thorough literature investigation, the nomenclatural problems have been resolved. This name was published in W. C. Cheng et al. (1975) and, although ascribed to "K. M. Feng", there is no suggestion that the descriptive material in the protologue was provided by K. M. Feng. Under Art. 46.5 of the ICN, this name should be attributed to K. M. Feng ex W. C. Cheng et al. but not to K. M. Feng alone. It has been claimed that the name is an illegitimate later homonym of one published by Beissner in 1901, but Beissner never accepted this name in any of his publications and so, under Art. 36.1, he did not validly publish an earlier homonym. Cephalotaxuslanceolatus was first validly published in W. C. Cheng et al. (1975).

Classification for β-Lactamases: Historical Perspectives

INTRODUCTION

-Lactamases are some of the most prevalent and well-studied families of enzymes, especially in the area of antibiotic resistance. Early attempts to categorize them used either functional names such as penicillinase or cephalosporinase or structural designations into classes A and D. Increasing diversity of the properties of these enzymes has required a more expansive approach to nomenclature.

AREAS COVERED

Historical designations for the early -lactamases relied heavily on functional names based on the biochemical properties of purified enzymes. As amino acid sequences began to be reported for a select group of these enzymes, classes of -lactamases were defined, with a major lumping of enzymes into those that had active site serine residues (class A, C and D) and those that were metallo-lactamases (MBLs, or class D). More recent classification schemes as determined through a Medline search have attempted to incorporate both functional and structural features, using functional groups and subgroups to name -lactamases within the same structural class. Nomenclature of these enzymes is now under the purview of the NCBI (National Center for Biotechnology Information).

EXPERT OPINION

-Lactamase nomenclature will continue to evolve with the identification of new enzymes and new functionalities.

Hoyaspectatissima (Gentianales, Apocynaceae), a new species from Yunnan, China

Hoyaspectatissima, a new species from Yunnan Province, China, is described and illustrated. Hoyaspectatissima is morphologically similar to H.lyi, but can be easily distinguished from the latter by its succulent leaves that are 2‒4.5 cm long (vs. coriaceous leaves that are up to 9 cm long), corolla that is pink to pale pink (vs. yellowish-white) and corona lobes that are sub-rhombic in top view (vs. ovoid in top view).

New Approach to the Systematics of the Section Psammiris (Iris, Iridaceae): What Does Chloroplast DNA Sequence Tell Us?

Iris sect. Psammiris comprises rhizomatous perennials distributed in the north temperate zone of Eurasia. The systematics of the section are currently based on morphology, and the phylogenetic relationships within it still remain unclear. In the framework of Iris systematics, we conducted molecular and morphological analyses of the currently recognized I. sect. Psammiris species to elucidate the taxonomic composition and relationships within the section. The phylogenetic reconstructions based on sequence variation of four noncoding chloroplast DNA regions support the monophyly of I. sect. Psammiris, which includes I. tigridia, while I. potaninii var. ionantha belongs to I. sect. Pseudoregelia. The proposed novel classification of I. sect. Psammiris recognizes three series: an autonymic series with I. humilis, I. bloudowii, and I. vorobievii and two unispecific series (I. ser. Potaninia with I. potaninii and I. ser. Tigridiae with I. tigridia). In addition, the taxonomic statuses of I. arenaria, I. ivanovae, I. kamelinii, I. mandshurica, I. pineticola, I. psammocola, and I. schmakovii are clarified herein. We provide a revised taxonomic treatment for I. sect. Psammiris, including notes on the types; updated information on species synonymy, distributions, habitats, and chromosome numbers; and a new identification key to the species. Three lectotypes are designated here.

Taxonomy and nomenclature of Abutilonalbidum (Malvaceae, Malvoideae), a cryptic Saharo-Canarian species recently rediscovered in Tenerife

Abutilonalbidum, a cryptic Saharo-Canarian species, was thought to have been last collected in 1945 in Tenerife by E.R. Sventenius. In 2019, it was rediscovered in the same area. The characteristic features of the Canarian plants are discussed, especially in relation to the morphologically similar-looking and probably closely-related species Abutilonindicum and A.bidentatum. It is concluded that the plants from Tenerife and north-western Africa indeed represent a distinct species. The species is illustrated and a key for the identification of this and related species is presented.

Description and nomenclature of organ subdivisions in the Terminologia Anatomica and in anatomical education: Comparison with cancer classifications

Terminology is the basis for communication among medical professionals. For anatomists, their daily work is based on the Terminologia Anatomica (TA), while pathologists cite the Tumor Node Metastasis (TNM) classification when referring to the anatomical boundaries and regions of malignant tumors. Terminologia Anatomica and clinical-based classifications, including the TMN classification of tumors, use a world-wide standardized nomenclature, which has been revised regularly to incorporate new anatomical discoveries and clinically relevant structures. In medical education, students are familiarized with medical nomenclatures in anatomy textbooks and online learning platforms. Sometime, descriptions and illustrations in anatomy teaching materials put a different focus on the importance of anatomical subdivisions and their borders than is found in cancer classifications. This discrepancy contrasts with the efforts of medical societies to define and implement clinically relevant anatomical structures, including organ subdivisions and their boundaries, in daily clinical practice. Here, we illustrate this problem using the larynx and pancreas as examples. Anatomy education should coordinate teaching content with the requirements of the clinical disciplines.

Development of meat analogs: Focus on the current status and challenges of regulatory legislation

Population growth and the rising enthusiasm for meat consumption in developing countries have increased the global demand for animal protein. The limited increase in traditional meat production, which results in high resource consumption, greenhouse gas emissions, and zoonotic diseases, has affected the sustainable supply of meat protein. The technological development and commercialization of meat analogs derived from plant and microbial proteins provide a strategy for solving the abovementioned problems. However, before these innovative foods are marketed, they should comply with regulations and standards to ensure food safety and consumer rights. This review briefly summarizes the global development status and challenges of plant- and fungi-based meat analog products. It focuses on the current status, characteristics, and disputes in the regulations and standards worldwide for plant- and fungi-based meat analogs and proposes suggestions for perfecting the regulatory system from the perspective of ensuring safety and supporting innovation. Although plant- and fungi-based meat analogs have had a history of safe usage as foods for a certain period around the world, the nomenclature and product standards are uncertain, which affects product innovation and global sales. Regulatory authorities should promptly formulate and revise regulations or standards to clarify the naming of meat analogs and product standards, especially the use of animal-derived ingredients and limits of nutrients (e.g., protein, fat, vitamins, and minerals) to continuously introduce start-up products to the market.

Naming new taxa of prokaryotes in the 21st century

The nomenclature of prokaryotes is regulated by the rules of the International Code of Nomenclature of Prokaryotes (ICNP) and is based on the Linnaean binomial system. The current rules of the Code only cover the nomenclature of the cultivated minority. Proposals to incorporate the uncultivated majority of bacteria and archaea under the rules of the Code were recently rejected by the International Committee on Systematics of Prokaryotes. The provisional rank of Candidatus can be used to name uncultivated prokaryotes whose names cannot be validly published under the rules of the ICNP, but their names can now be validated under the Code of Nomenclature of Prokaryotes Described from Sequence Data (the SeqCode), which was recently established to cover the nomenclature of the uncultivated majority. Metagenomics, single-cell genomics, and high-throughput cultivation techniques have led to a flood of new organisms currently waiting to be named. Automated programs such as GAN and Protologger can assist researchers in naming and describing newly discovered prokaryotes, cultivated as well as uncultivated. However, Latin and Greek skills remain indispensable for proper quality control of names that must meet the standards set by the codes of nomenclature.

(Compositae, Anthemideae) Representatives

Based on the results of a preceding species-delimitation analysis for the diploid representatives of the genus Leucanthemum (Compositae, Anthemideae), the present study aims at the elaboration of a specific and subspecific taxonomic treatment of the tetraploid members of the genus. Following an integrative taxonomic approach, species-level decisions on eight predefined morphotaxon hypotheses were based on genetic/genealogical, morphological, ecological, and geographical differentiation patterns. ddRADseq fingerprinting and SNP-based clustering revealed genetic integrity for six of the eight morphotaxa, with no clear differentiation patterns observed between the widespread L. ircutianum subsp. ircutianum and the N Spanish (Cordillera Cantábrica) L. cantabricum and the S French L. delarbrei subsp. delabrei (northern Massif Central) and L. meridionale (western Massif Central). The inclusion of differentiation patterns in morphological (leaf dissection and shape), ecological (climatological and edaphic niches), and geographical respects (pair-wise tests of sympatry vs. allopatry) together with the application of a procedural protocol for species-rank decisions (the 'Wettstein tesseract') led to the proposal of an acknowledgement of the eight predefined morphotaxon hypotheses as six species (two of them with two subspecies). Nomenclatural consequences following from these results are drawn and lead to the following new combinations: Leucanthemum delarbrei subsp. meridionale (Legrand) Oberpr., T.Ott & Vogt, comb. nov. and Leucanthemum ruscinonense (Jeanb. & Timb.-Lagr.) Oberpr., T.Ott & Vogt, comb. et stat. nov.

Dearth of ICD Codes for Complications of Immune Checkpoint Inhibitors Impedes Clinical Care and Research

Immune checkpoint inhibitors (ICIs) are a rapidly expanding class of targeted therapies effective in the treatment of various cancers. However, while efficacious, ICIs have been associated with treatment complications, namely immune-related adverse events (irAEs). IrAEs of the endocrine system are among the most commonly reported irAEs, but despite their high incidence, standardized disease definitions and endocrine IrAE-specific International Classification of Diseases (ICD) codes remain lacking. This dearth of standardized nomenclature and ICD codes has in many ways impeded both the clinical care of patients and the progress of endocrine irAE-related research. ICD codes are used internationally and are essential for medical claims reporting in the health care setting, and they provide a universal language system for recording, reporting, and monitoring diseases. These codes are also a well-accepted form of electronic health record data capture that facilitates the collection, storage, and sharing of data. Therefore, the lack of standardized disease definitions and ICD codes has been associated with misclassification and suboptimal management of individuals with endocrine irAEs and has also been associated with reduced data availability, comparability, and quality. Harmonized and clinically relevant disease definitions along with the subsequent development of endocrine-irAE-specific ICD codes will provide a systematic approach to understanding the spectrum and burden of endocrine irAE diseases, and will have a positive effect across clinical, public health, and research settings.

Vascular anomalies: nomenclature, classification, and imaging algorithms

There is a lot of ambiguity in the usage of correct terminology in the description of vascular malformations and tumors. Hemangioma and arteriovenous malformation (AVM) are the most commonly used terms and are the mostly incorrectly used as well! The aim of this review article was to lay out the correct nomenclature and describe the correct usage for the physicians and radiologists involved in diagnosing and managing these lesions. We describe the various classification systems which have been devised to define the multiple entities included under vascular anomalies. The latest classification system that should be adhered to is per the International Society for the Study of Vascular Anomalies, approved at the 20th ISSVA Workshop held in Melbourne in April 2014, last revised in May 2018. The main features of the latest revision have been highlighted. This classification, however, does not list the diagnostic clinico-radiological features for each entity. In addition, guidelines regarding the appropriate use of available imaging modalities are lacking in the literature. We, hereby, aim to address these pertinent issues in this review article.

The 2022 WHO classification of thyroid tumors: novel concepts in nomenclature and grading

The fifth edition of the Classification of Endocrine and Neuroendocrine Tumors has been released by the World Health Organization. This timely publication integrates several changes to the nomenclature of non-neoplastic and neoplastic thyroid diseases, as well as novel concepts that are essential for patient management. The heterogeneous group of non-neoplastic and benign neoplastic lesions are now collectively termed as 'thyroid follicular nodular disease' to better reflect the clonal and non-clonal proliferations that clinically present as multinodular goiter. Thyroid neoplasms originating from follicular cells are distinctly divided into benign, low-risk and malignant neoplasms. The new classification scheme stresses that papillary thyroid carcinoma (PTC) should be subtyped based on histomorphologic features irrespective of tumor size to avoid treating all sub-centimeter/small lesions as low-risk disease. Formerly known as the cribriform-morular variant of PTC is redefined as cribriform-morular thyroid carcinoma since this tumor is now considered a distinct malignant thyroid neoplasm of uncertain histogenesis. The 'differentiated high-grade thyroid carcinoma' is a new diagnostic category including PTCs, follicular thyroid carcinomas and oncocytic carcinomas with high-grade features associated with poorer prognosis similar to the traditionally defined poorly differentiated thyroid carcinoma as per Turin criteria. In addition, squamous cell carcinoma of the thyroid is now considered a morphologic pattern/subtype of anaplastic thyroid carcinoma. In this review, we will highlight the key changes in the newly devised fifth edition of the WHO classification scheme of thyroid tumors with reflections on its applicability in patient management and future directions in this field.

The utility of the 'Arable Weeds and Management in Europe' database: Challenges and opportunities of combining weed survey data at a European scale

Over the last 30 years, many studies have surveyed weed vegetation on arable land. The 'Arable Weeds and Management in Europe' (AWME) database is a collection of 36 of these surveys and the associated management data. Here, we review the challenges associated with combining disparate datasets and explore some of the opportunities for future research that present themselves thanks to the AWME database. We present three case studies repeating previously published national scale analyses with data from a larger spatial extent. The case studies, originally done in France, Germany and the UK, explore various aspects of weed ecology (community composition, management and environmental effects and within-field distributions) and use a range of statistical techniques (canonical correspondence analysis, redundancy analysis and generalised linear mixed models) to demonstrate the utility and versatility of the AWME database. We demonstrate that (i) the standardisation of abundance data to a common measure, before the analysis of the combined dataset, has little impact on the outcome of the analyses, (ii) the increased extent of environmental or management gradients allows for greater confidence in conclusions and (iii) the main conclusions of analyses done at different spatial scales remain consistent. These case studies demonstrate the utility of a Europe-wide weed survey database, for clarifying or extending results obtained from studies at smaller scales. This Europe-wide data collection offers many more opportunities for analysis that could not be addressed in smaller datasets; including questions about the effects of climate change, macro-ecological and biogeographical issues related to weed diversity as well as the dominance or rarity of specific weeds in Europe.

Point-Counterpoint: What's in a Name? Clinical Microbiology Laboratories Should Use Nomenclature Based on Current Taxonomy

INTRODUCTION The mnemonic SPICE (Serratia, Pseudomonas, indole-positive Proteus, Citrobacter, and Enterobacter) has served as a reminder to consider when a Gram-negative organism may carry a chromosomal copy of bla_ampC, with the associated risk of developing resistance to first-, second-, and third-generation cephalosporins. However, in 2017, there was a well-founded proposal to rename Enterobacter aerogenes to Klebsiella aerogenes, based on whole-genome sequencing (WGS), and the SPICE mnemonic lost its relevance. With the increased use of WGS for taxonomy, it seems like bacteria and fungi are undergoing constant name changes. These changes create unique challenges for clinical microbiology laboratories, who would like to issue reports that are readily understood and that help clinicians determine empirical antibiotic therapy, interpret antimicrobial resistance, and understand clinical significance. In this Point-Counterpoint, Drs. Karen Carroll and Erik Munson discuss the pros of updating bacterial taxonomy and why clinical labs must continue to update reporting, while Drs. Susan Butler-Wu and Sheila Patrick argue for caution in adopting new names for microorganisms.

Taxonomy and Distribution of Spiraea hypericifolia in Italy and Typification of the Name S. flabellata (Rosaceae)

Spiraea hypericifolia is a Eurasiatic species, distributed from SW Europe to C and SW Asia. In Italy, only the alien S. hypericifolia subsp. obovata was recorded, as naturalized in the Central Apennines. Spiraea flabellata was described from Abruzzo (Central Apennines, Italy) by Gussone in 1826 and is currently regarded as a synonym of S. hypericifolia subsp. obovata. Based on the study of living plants from locus classicus and the analysis of the original material traced in BOLO and NAP, S. flabellata should be referred instead to S. hypericifolia subsp. hypericifolia, a taxon reported here for the first time in Italy. The name S. flabellata is lectotypified with a specimen kept in NAP. Based on our study, S. hypericifolia subsp. obovata should be excluded from Italian flora. Spiraea hypericifolia subsp. hypericifolia should be considered native to Italy and added to the contingent of steppe plants of phytogeographic and conservation interest recorded in the Central Apennines. Finally, the conservation status assessment of S. hypericifolia subsp. hypericifolia according to IUCN categories and criteria, is proposed and discussed.

Adonis fucensis (A. sect. Adonanthe, Ranunculaceae), a New Species from the Central Apennines (Italy)

Adonis fucensis is herein described as a new species based on morphological and molecular analyses. It is endemic to one locality of the Central Apennines between Amplero and Fucino plains within the NATURA 2000 network in the SAC IT7110205 (Central Italy). The only discovered population is composed of 65 individuals and is at risk of extinction. The conservation status assessment according to IUCN categories and criteria is proposed and discussed. The new species belongs to A. sect. Adonanthe and is morphologically similar to A. volgensis (incl. A. transsilvanica), a species distributed in Hungary, Romania, Bulgaria, and Turkey as well as eastward to SW Siberia and Central Asia. Adonis fucensis can be distinguished from A. volgensis by larger cauline leaves, pentagonal with lobes lanceolate, larger stipules with more lobes and teeth, and larger flowers. Finally, an analytical key to Adonis species belonging to sect. Adonanthe distributed in Europe is presented.

Fungal Nomenclature: Managing Change is the Name of the Game

Fungal species have undergone and continue to undergo significant nomenclatural change, primarily due to the abandonment of dual species nomenclature in 2013 and the widespread application of molecular technologies in taxonomy allowing correction of past classification errors. These have effected numerous name changes concerning medically important species, but by far the group causing most concern are the Candida yeasts. Among common species, Candida krusei, Candida glabrata, Candida guilliermondii, Candida lusitaniae, and Candida rugosa have been changed to Pichia kudriavzevii, Nakaseomyces glabrata, Meyerozyma guilliermondii, Clavispora lusitaniae, and Diutina rugosa, respectively. There are currently no guidelines for microbiology laboratories on implementing changes, and there is ongoing concern that clinicians will dismiss or misinterpret laboratory reports using unfamiliar species names. Here, we have outlined the rationale for name changes across the major groups of clinically important fungi and have provided practical recommendations for managing change.

Thirteen new species of butterflies (Lepidoptera: Hesperiidae) from Texas

Analyses of whole genomic shotgun datasets, COI barcodes, morphology, and historical literature suggest that the following 13 butterfly species from the family Hesperiidae (Lepidoptera: Papilionoidea) in Texas, USA are distinct from their closest named relatives and therefore are described as new (type localities are given in parenthesis): Spicauda atelis Grishin, new species (Hidalgo Co., Mission), Urbanus (Urbanus) rickardi Grishin, new species (Hidalgo Co., nr. Madero), Urbanus (Urbanus) oplerorum Grishin, new species (Hidalgo Co., Mission/Madero), Telegonus tsongae Grishin, new species (Starr Co., Roma), Autochton caballo Grishin, new species (Hidalgo Co., 6 mi W of Hidalgo), Epargyreus fractigutta Grishin, new species (Hidalgo Co., McAllen), Aguna mcguirei Grishin, new species (Cameron Co., Brownsville), Polygonus pardus Grishin, new species (Hidalgo Co., McAllen), Arteurotia artistella Grishin, new species (Hidalgo Co., Mission), Heliopetes elonmuski Grishin, new species (Cameron Co., Boca Chica), Hesperia balcones Grishin, new species (Travis Co., Volente), Troyus fabulosus Grishin, new species (Hidalgo Co., Peñitas), and Lerema ochrius Grishin, new species (Hidalgo Co., nr. Relampago). Most of these species are known in the US almost exclusively from the Lower Rio Grande Valley in Texas. Nine of the holotypes were collected in 1971-1975, a banner period for butterfly species newly recorded from the Rio Grande Valley of Texas; five of them collected by William W. McGuire, and one by Nadine M. McGuire. At the time, these new species have been recorded under the names of their close relatives. A Neotype is designated for Papilio fulminator Sepp, [1841] (Suriname). Lectotypes are designated for Goniurus teleus Hübner, 1821 (unknown, likely in South America), Goniloba azul Reakirt, [1867] (Mexico: Veracruz) and Eudamus misitra Plötz, 1881 (Mexico). Several taxonomic changes are proposed. The following taxa are species (not subspecies): Spicauda zalanthus (Plötz, 1880), reinstated status (not Spicauda teleus (Hübner, 1821)), Telegonus fulminator (Sepp, [1841]), reinstated status (not Telegonus fulgerator (Walch, 1775), Telegonus misitra (Plötz, 1881), reinstated status (not Telegonus azul (Reakirt, [1867])), Autochton reducta (Mabille and Boullet, 1919), new status (not Autochton potrillo (Lucas, 1857)), Epargyreus gaumeri Godman and Salvin, 1893, reinstated status (not Epargyreus clavicornis (Herrich-Schäffer, 1869)), and Polygonus punctus E. Bell and W. Comstock, 1948, new status (not Polygonus savigny (Latreille, [1824])). Urbanus ehakernae Burns, 2014 and Epargyreus socus chota Evans, 1952 are junior subjective synonyms of Urbanus alva Evans, 1952 and Epargyreus clavicornis (Herrich-Schäffer, 1869), respectively, and Epargyreus gaumeri tenda Evans, 1955, new combination is not a subspecies of E. clavicornis.

Da Vinci's yeast: Blastobotrys davincii f.a., sp. nov

A new species of the yeast genus Blastobotrys was discovered during a worldwide survey of culturable xerophilic fungi in house dust. Several culture-dependent and independent studies from around the world detected the same species from a wide range of substrates including indoor air, cave wall paintings, bats, mummies, and the iconic self-portrait of Leonardo da Vinci from ca 1512. However, none of these studies identified their strains, clones, or OTUs as Blastobotrys. We introduce the new species as Blastobotrys davincii f.a., sp. nov. (holotype CBS H-24879) and delineate it from other species using morphological, phylogenetic, and physiological characters. The new species of asexually (anamorphic) budding yeast is classified in Trichomonascaceae and forms a clade along with its associated sexual state genus Trichomonascus. Despite the decade-old requirement to use a single generic name for fungi, both names are still used. Selection of the preferred name awaits a formal nomenclatural proposal. We present arguments for adopting Blastobotrys over Trichomonascus and introduce four new combinations as Blastobotrys allociferrii (≡ Candida allociferrii), B. fungorum (≡ Sporothrix fungorum), B. mucifer (≡ Candida mucifera), and Blastobotrys vanleenenianus (≡ Trichomonascus vanleenenianus). We provide a nomenclatural review and an accepted species list for the 37 accepted species in the Blastobotrys/Trichomonascus clade. Finally, we discuss the identity of the DNA clones detected on the da Vinci portrait, and the importance of using appropriate media to isolate xerophilic or halophilic fungi.
