Abstract
Utilising both morphological and molecular analyses, this study unveils Mazusjiangshiensesp. nov., a novel addition to the Mazaceae family, discovered in Shaowu County, Fujian Province, China. The comprehensive description and illustrations provided here are a result of a meticulous exploration of its morphological features. While bearing a resemblance to M.gracilis, this new-found species is distinguished by three distinct characteristics: its stems are delicately soft, its leaves possess a membranous quality and the ovary is notably villous at the apex. Integration of molecular evidence, derived from the nuclear ribosomal DNA (nrITS) and three plastid DNA sequences (rps16, rbcL and trnL-trnF), unequivocally supports the classification of M.jiangshiense as a distinct species. Notably, the molecular analysis positions it as a sister species to M.spicatus, underscoring the phylogenetic relationships within the genus Mazus. Our research not only introduces M.jiangshiense as a novel taxonomic entity, but also provides a nuanced understanding of its morphological differences and molecular affinities, enriching our comprehension of the diversity and evolutionary relationships of Mazaceae.

Abstract
Mazusmotuoensis W.B.Ju, Bo Xu bis & X.F.Gao is a newly described species found in Xizang Autonomous Region, China. Morphologically, this species differs from all the other known Mazus species by having erect perennial herb form with a rhizome, presence of multicellular hairs, without basal leaves, opposite arrangement of stem leaves, and corolla lobes with erose-toothed margins. Molecular phylogenetic analysis using nuclear and cpDNA genes suggests that this new species occupies a basal position within Mazus. In conclusion, both morphological evidence and molecular phylogenetic analyses support that this species belongs to Mazus and represents an as-yet-unreported new species with distinct differences from other species within the genus.

Abstract
Six Mazaceae plastomes were assembled in this study, including the newly recognized genus, Puchiumazus. Comparative plastid genomic analysis provided new insights into Mazaceae. The phylogenetic categorization of Mazus lanceifolius (Mazaceae) has long been uncertain. In 2021, the scholars Bo Li, D. G. Zhang, and C. L. Xiang republished M. lanceifolius as a new species Puchiumazus lanceifolius, within a new genus Puchiumazus. However, there is little plastome information on Mazaceae. Following the publishing of the new genus Puchiumazus, it is now necessary to study the Mazaceae plastome features to comprehensively understand this young family. The Mazaceae plastomes all have a typical quartile structure. The plastomes have a size ranging from 152,388 to 154,252 bp, and each plastome contains 112 unique genes, including 78 protein-coding genes, 4 rRNA genes, and 30 tRNA genes. A comparative analysis showed that these plastome sequences are highly conserved. Furthermore, we identified four relatively hypervariable regions (trnQ-UUC-psbK, trnS-GCU- trnS-CGA, trnT-UGU-trnL-UAA and ycf1) that can be used as potential DNA barcodes for the identification of this clade. Phylogenetic relationships based on the whole plastome sequences of 25 samples of 14 genera of Lamiales placed M. lanceifolius in the basal clade of the family Mazaceae, with 100% bootstrap support. In summary, the M. lanceifolius results indicate that a new monotype genus (Puchiumazus) should be established at the whole-plastome level. This study provides plastid genomic resources for exploring the phylogeny of Mazaceae.
