Abstract
Orchidaceae are one of the largest families of angiosperms in terms of species richness. In the last decade, numerous studies have delved into reconstructing the phylogenetic framework of Orchidaceae, leveraging data from plastid, mitochondrial and nuclear sources. These studies have provided new insights into the systematics, diversification and biogeography of Orchidaceae, establishing a robust foundation for future research. Nevertheless, pronounced controversies persist regarding the precise placement of certain lineages within these phylogenetic frameworks. To address these discrepancies and deepen our understanding of the phylogenetic structure of Orchidaceae, we provide a comprehensive overview and analysis of phylogenetic studies focusing on contentious groups within Orchidaceae since 2015, delving into discussions on the underlying reasons for observed topological conflicts. We also provide a novel phylogenetic framework at the subtribal level. Furthermore, we examine the tempo and mode underlying orchid species diversity from the perspective of historical biogeography, highlighting factors contributing to extensive speciation. Ultimately, we delineate avenues for future research aimed at enhancing our understanding of Orchidaceae phylogeny and diversity.

Abstract
A taxonomic synopsis of the orchid genus Habenaria in New Guinea and adjacent islands is presented. We confirmed the occurrence of 27 Habenaria species in study area. Sixteen of these are endemic and were not so far found outside New Guinea. Morphological characteristics and illustrations of floral segments of taxa are presented. One new species of Habenaria is described. Four neotypes are selected. An updated key to species groups and species occurring in the study area is provided. The importance of diagnostic floral characters in Habenaria is discussed.

PLANT DIVERSITY 2021; 43:390-400. [PMID: 34816064 PMCID: PMC8591144 DOI: 10.1016/j.pld.2021.05.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/04/2020] [Revised: 05/21/2021] [Accepted: 05/23/2021] [Indexed: 06/13/2023]
Abstract
Four new species of Orchidaceae from China, Heminium lijiangense, Peristylus fasciculatus, Platanthera milinensis, and Ponerorchis gongshanensis, together with a new country record, Peristylus tenuicallus, are described and illustrated based on morphological and/or phylogenetic analyses. Heminium lijiangense is closely related to H. elisabethae but differs from it by having the dorsal sepal ovate-orbicular and lip mid-lobe distinctly shorter than lateral lobes. P. fasciculatus is close to Peristylus tradescantifolius but is distinguished from it by having several fascicled and straight, root-like tubers (vs. one or two oblongoid tubers), old stems usually persistent, middle lobe of lip narrowly ligulate-lanceolate and half as long as the lateral lobes (vs. middle lobe deltoid, about a third as long as the lateral lobes or less), a raised callus at the base of each lateral lobe (vs. callus absent), spur gradually attenuate toward the apex (vs. spur clavate). Platanthera milinensis is similar to P. stenochila by sharing small green flowers and lip without a spur, but differs in having a creeping rhizome, a corymbose inflorescence, and a broadly ovate and slightly 3-lobed lip. Ponerochis gongshanensis is similar to P. faberi in its small flowers, but differs in having a linear leaf c. 3 mm wide (vs. leaf 5-13 mm wide), in the lip having collar-like raised margins on the sides of the spur entrance, and a mid-lobe which is notched at the apex but not divided into two divergent lobules that are nearly as large as the lateral lobes, as in P. faberi. All the proposed species obtained high support in phylogenetic analysis as new species. The recently described genus Apetalanthe is reduced to synonymy of Ponerorchis and a new combination is made.
