Phytolacca exiensis, a new species of Phytolacca which was discovered from west of Hubei province, China, is discribed and illustrated in this paper. The placement of this new species is accessed based on molecular phylogenetic analysis of the nuclear ribosomal ITS and one chloroplast regions (psbA-trnH) sequences together with mophorlogical compar...

The Species Catalogue of China: Volume 1: Plants (SCCP) is a new, comprehensive, hardcopy inventory of Chinese higher plants that combines several datasets and references to recent taxonomic treatments. The database, with all attached additional information, is freely accessible via the internet (http://www.sp2000.org.cn/) and on CD‐ROM, and will b...

China is one of the diversity centers of gymnosperms. Nearly one-fifth (195 species) of gymnosperms are located in China, but 69 species are threatened. To date, the conservation status of gymnosperms, especially threatened gymnosperms in China, remains largely unknown, which seriously restricts the comprehensive protection of gymnosperms. Understa...

Climate change inevitably affects the geographical distribution of species on earth. Conifers, which are important components of forest tree species, are highly threatened and particularly sensitive to climate change. Approximately 23.6% (145/615 species) of the world’s conifers are native to China, among which 53 species are threatened. Thus, unde...

Duplicate genes are pivotal in driving evolutionary innovation, often exhibiting expression divergence that offers a system to investigate the role of DNA methylation in transcriptional regulation. However, previous studies have predominantly focused on angiosperms, leaving the methylation patterns in major lineages of land plants still unclear. Th...

A species could not be known to the world of science if it not be discovered and described, considerable number of new species are neglected due to the plant itself and some other external restricted factors. On the basis of morphological and molecular evidences, a new species previously identified as Salvia scapiformis is now described and illustr...

Conservation of plant diversity is essential in the current status of rapid biodiversity loss. A critically endangered species of Oleaceae, Osmanthus pubipedicellatus was rediscovered in its type locality after nearly a century based on morphological and molecular evidence, further supplemented by a revised description. Meanwhile, the static life t...

Assessing sampling biases caused by nonrandom specimen collecting is crucial in systematics, biogeography, and conservation. Nevertheless, research on the collecting biases of vascular plants in China remains limited. Here, we investigated the collecting status of gymnosperms in China using 48 673 herbarium specimens representing 180 Chinese gymnos...

Concentrating limited resources to protect as many species as possible is the most effective way to improve conservation efficiency, of which identifying the clustering characteristics of species in urgent need of conservation is a prerequisite. In this study, selectivity was used to characterize the taxonomic and geographic clustering characterist...

Aster sanqingshanica J.W. Xiao & W.P. Li, a new species of Asteraceae from Jiangxi, China, is described, illustrated and compared with related taxa based on evidence from morphology and molecular phylogeny. Morphological observations have shown that A. sanqingshanica is most similar to A. tianmenshanensis, but readily differs by its ascending stem...

Adenophora xiaoxiensis (Campanulaceae), a new species from central China is described and illustrated. Molecular phylogenetic analysis (based on nuclear ribosomal ITS and the plastid regions trnL-F and matK) and morphology support recognition of A. xiaoxiensis as a distinct species sister to A. wilsonii. Adenophora xiaoxiensis has ovate-elliptic to...

The uncertain threat status of species inevitably influences their focus on conservation. Just as in extinction risk, the non-randomness phenomenon related to uncertainty (also referred to as selectivity), which is a certain character cluster in some groupings, also exists in data deficiency of species’ knowledge. In order to illustrate this kind o...

Prunus nutantiflora D.G. Zhang & Z.H. Xiang sp. nova (Rosaceae) from Hunan Province, China, is described, illustrated and compared with morphologically similar species. Prunus nutantiflora resembles especially P. xueluoensis in having three axillary winter buds and an ellipsoid drupe, but differs from it by having a densely pilose style base and a...

In this paper, we make a report on new records of medicinal plants in Hubei, which include one newly recorded genera and seven newly recorded species and a newly recorded variety. The newly recorded genera is Anoectochilus and its corresponding species is Anoectochilus roxburghii; These newly recorded species are Euphorbia micractina, Astragalus wu...

Seven species were reported as new records of Jiangxi province, which collected from Wugongshan region, including Huperzia kunmingensis(Lycopodiaceae), Hydrangea mangshanensis(Saxifragaceae), Itea glutinosa(Saxifragaceae), Stellaria monosperma var. japonica(Lycopodiaceae), Youngia pratti(Compositae), and Calanthe henryi(Orchidaceae), Collabium form...
