We reconstructed a phylogenetic tree of Chinese vascular plants (Tracheophyta) using sequences of the chloroplast genes atpB, matK, ndhF, and rbcL and mitochondrial matR. We produced a matrix comprising 6098 species and including 13 695 DNA sequences, of which 1803 were newly generated. Our taxonomic sampling spanned 3114 genera representing 323 families of Chinese vascular plants, covering more than 93% of all genera known from China. The comprehensive large phylogeny supports most relationships among and within families recognized by recent molecular phylogenetic studies for lycophytes, ferns (monilophytes), gymnosperms, and angiosperms. For angiosperms, most families in Angiosperm Phylogeny Group IV are supported as monophyletic, except for a paraphyletic Dipterocarpaceae and Santalaceae. The infrafamilial relationships of several large families and monophyly of some large genera are well supported by our dense taxonomic sampling. Our results showed that two species of Eberhardtia are sister to a clade formed by all other taxa of Sapotaceae, except Sarcosperma. We have made our phylogeny of Chinese vascular plants publically available for the creation of subtrees via SoTree (, an automated phylogeny assembly tool for ecologists. © 2016 Institute of Botany, Chinese Academy of Sciences

The sunflower family (Asteraceae) is the largest and the most diverse flowering plant family, comprising 24 000–30 000 species and 1600–1700 genera. In China, Asteraceae are also the largest family, with approximately 2336 indigenous species in 248 genera. In the past two decades, molecular phylogenetic analyses has contributed greatly to our understanding of the systematics of Asteraceae. Nevertheless, the large-scale analyses and knowledge about the relationships of Chinese Asteraceae at the generic level as a whole are far from complete due to difficulties in sampling. In this study, we presented a three-marker (rbcL, ndhF, and matK) phylogeny of Asteraceae, including 506 genera (i.e., approximately one-third of Asteraceae genera). The study sampled 200 Chinese genera (i.e., approximately 80% of Chinese Asteraceae genera). The backbones of the new phylogeny were largely congruent with earlier studies, with 13 subfamilies and 45 tribes recognized. Chinese Asteraceae were distributed in 7 subfamilies (Mutisioideae, Wunderlichioideae, Carduoideae, Pertyoideae, Gymnarrhenoideae, Cichorioideae, and Asteroideae) and 22 tribes (Mutiseae, Hyalideae, Cardueae, Pertyeae, Gymnarrheneae, Vernonieae, Cichorieae, Doroniceae, Senecioneae, Astereae, Anthemideae, Gnaphalieae, Calenduleae, Inuleae, Athroismeae, Helenieae, Coreopsideae, Neurolaeneae, Tageteae, Millieae, Eupatorieae, and Heliantheae). Chinese Asteraceae lacked 6 basal subfamilies and 23 tribes. Several previously ambiguous relationships were clarified. Our analyses also resolved some unplaced genera within Chinese Asteraceae. Finally, our phylogenetic tree was used to revise the classification for all genera of Chinese Asteraceae. In total, 255 genera, 22 tribes, and 7 subfamilies in China are recognized. © 2016 Institute of Botany, Chinese Academy of Sciences

Hattorioceros (J. Haseg.) J. Haseg. is a monospecific genus of hornworts with a single species, H. striatisporus (J. Haseg.) J. Haseg., previously known only from the Western Himalayas and Fiji. Here we report this genus as a new addition for China from Xizang (Tibet). Some previously unknown morphological characters, such as the presence of a single chloroplast with a pyrenoid per cell and the number of antheridia per chamber are added to the generic description. © 2011 by the American Bryological and Lichenological Society, Inc.

The spores of the monospecific genus Hattorioceros are ovoid to spheroid with canaliculate-striate surface ornamentation, and are unique among hornworts. We determine here for the first time the phylogenetic position of the genus using sequence data from the chloroplast rbcL and mitochondrial nad5 genes. Hattorioceros is nested within Phaeoceros, challenging its taxonomic status. Although spore morphology is a key feature in hornwort taxonomy, our results suggest that caution must be taken when describing taxa above the species level based solely on a single character.

In this paper, two new species of genus Bazzania, B. dulongensis L.-P.Zhou & L.Zhang and B. hainanensis L.-P.Zhou & L.Zhang, are described from China. B. dulongensis is characterized by its oblong leaves and irregularly denticulate apex of its underleaves; it differs from B. okaritana Meagher & Glenny in the shape of leaf cells and the apex of the underleaves. B. hainanensis is distinguished from its congeners by its almost entire leaf apex and the denticulate apex of its underleaves. In addition, B. adnexa (Lehm. & Lindenb.) Trevis., B. angustistipula N.Kitag., B. asymmetrica (Steph.) N.Kitag. and B. fleischeri (Steph.) Abeyw. are included as new additions to China. Detailed descriptions of the new species and illustrations of the six species are presented. © British Bryological Society 2012.
