Chrysosplenium sangzhiense Hong Liu, a new species from Hunan, China, is described and illustrated. The phylogenetic analysis revealed that the belongs to subgen. closely related C. grayanum , nepalense sinicum . chromosome number of 2n = 46, indicating novel basic x 23 in different other species. This also suggests probably an allopolyploid derivative with 11 one 12. Morphologically, can be easily distinguished cavaleriei not included our by suite characters relating sterile shoots, basal...

Chrysosplenium L. (Saxifragaceae) is a genus of plants widely distributed in Northern Hemisphere and usually found moist, shaded valleys mountain slopes. This ideal for studying plant adaptation to low light conditions. Although some progress has been made the systematics biogeography Chrysosplenium, its chloroplast genome evolution remains be investigated.

A new species of Chrysosplenium (Saxifragaceae), C. zhangjiajieense, is described and illustrated from Zhangjiajie, Hunan province in China. This similar to macrophyllum having broad basal leaves compact cymes, but it differs the latter that whole plant zhangjiajieense densely covered by coarse long white villus, leaf adaxial surface bears thickly wart points. The also davidianum, flowers, only one cauline leaf, oblong sepals stamen longer than while davidianum possess yellow flower, 2–5...

Chrysosplenium zhouzhiense Hong Liu, a new species from Shaanxi, north-western China, is described and photographed. The belongs to Subgen. Gamosplenium Sect. Nephrophylloides Ser. Macrophylla most similar C. macrophyllum zhangjiajieense which it differs by having shorter stem, rhizome absent, basal leaf sterile branch arising the flowering stem light yellow flower with longer stamen. A global conservation assessment performed classifies as Endangered (EN).

As a traditional Chinese medicinal material, Chrysosplenium is urgently needed for genetic resource investigation and protection research due to the decrease of its wild resources in recent years. After investigating resources, we conducted polymorphism clustering studies 24 species(a total 36 samples) using SRAP technique. The results showed that 374 polymorphic bands were obtained 18 pairs primers amplify these samples, on average 20.7 each primer pair. We used biological software analyze...

Chrysosplenium guangxiense H.G.Ye & Gui C.Zhang was first described as a new species in 1994 but later synonymized the Flora of China treatment with C. glossophyllum H.Hara. Plastid genomes and nrDNA sequences were used to infer phylogenetic relationships selected taxa . Our analyses revealed that belongs sect. Alternifolia, is closely related hydrocotylifolium H.Lév. Vaniot distant from Morphologically, could be easily distinguished by having robust rhizomes, basal leaves long cuneate...

(Orchidaceae), is a new species discovered in the Shibali Long Canyon National Nature Reserve, Zhuxi County, Hubei Province, China. It morphologically similar to

Abstract Background : Chrysosplenium L. (Saxifragaceae) is a genus of plants widely distributed in Northern Hemisphere and usually found moist, shaded valleys mountain slopes. This ideal for studying plant adaptation to low-light conditions. Although some progress has been made the systematics biogeography , its chloroplast genome evolution remains be investigated. Results To fill this gap, we sequenced genomes six species analyzed their structure, GC content, nucleotide diversity. Moreover,...

A new orchid species, is described and illustrated. Hemipilia zhuxiensis from the Shibali Long Canyon National Nature Reserve, Hubei Province, China, which morphologically similar to henryi calophylla . This species assigned H section but differs other in having gibbous lip, shorter spur unobvious lobes. Phylogenetic analyses were also conducted based on three plastid DNA regions ( matK , trnL intron trnL-F spacer). The revealed phylogenetic relations between this its close allies.
