Geum sunhangii (Rosaceae), a new species from Hubei Province, China.

ABSTRACT: Geum sunhangii - first discovered in Shennongjia National Nature Reserve, Hubei Province, China - is described as a new species of Rosaceae. Compared to all known Chinese Geum species, the new species differs by possessing jointed styles, imbricate petals and a reniform radical leaf terminal leaflet. Most significantly, the jointed style is curved at an obtuse or a right angle. In addition, the inclusion of this species within the genus Geum was supported by phylogenetic analysis using the sequence data of a nuclear ribosomal internal transcribed spacer (nrITS) and a chloroplast trnL-trnF intergenic spacer. The new species was found to be closely related to G. rivale and G. aleppicum.

Primula sunhangii (Primulaceae): a new species from Hubei, Central China.

Project description:This report provides a description of Primula sunhangii from the Shennongjia Forestry District, Hubei Province in Central China, which is categorized as a new species of the primrose family. Primula sunhangii is morphologically similar to P. involucrata Wall. ex Duby in terms of its simple umbel, efarinose, and prolonged bracts. However, P. sunhangii is distinguished by its glabrous sepal, short petiole (compare with blade) and cylindrical calyx and capsule. Molecular phylogenetic analysis based on nuclear and cpDNA genes demonstrates that P. sunhangii and P. involucrata are closely related. Combining genetic and morphological data, the recognition of P. sunhangii as a unique new species is supported.

A new species of Eriobotrya (Rosaceae) from Yunnan Province, China.

Project description:Eriobotrya laoshanica, a new species of Rosaceae from Yunnan, China, is described and illustrated. The new species is easily distinguished from the most similar species E. malipoensis K. C. Kuan by its longer petioles (2-5 vs. 0.5-1 cm); indumentum on the lower leaf surfaces (densely tomentose vs. glabrous); much fewer flowers (15- to 30-flowered vs. 50- to 100-flowered) on the panicle; larger flowers (2.5-3 vs. 1.5-2 cm in diameter); and non-angulated (vs. angulated) young fruits.

Vitisshizishanensis, a new species of the grape genus from Hubei province, China.

Project description:Vitisshizishanensis (Vitaceae), a new species from Hubei, China, is described and illustrated. It is morphologically similar to V.flexuosa and V.bryoniifolia, but differs in leaf lobing and pubescence. It can be easily distinguished from the two species based on its glabrous or with very sparse arachnoid tomentum on the abaxial mature leaf surface, and its unlobed to 3-7 lobed leaves. A detailed description, along with photographs for the new species, and a table for morphological comparisons with similar Vitis species, are also provided.

Silene sunhangii (Caryophyllaceae), a new species from China.

Project description:Silene sunhangii, a new species of Caryophyllaceae known from only three populations in Hubei and Hunan provinces of central China, is described. Both morphological and molecular data were used to assess the taxonomic status and relationships of this species. Morphologically, S. sunhangii is most similar to S. platyphylla Franch. from which it differs most readily in having 3-veined elliptical leaves without pubescence, tasseled catacorolla, pale purple to red petals without a linear lobe or narrow tooth and lanceolate, bifid to one third. A phylogenetic analysis based on nuclear ITS region identified the new species as a well-supported, independent lineage. Our new species is nested within a grade that encompasses species representing a polyphyletic Silene sect. Physolychnis (Benth.) Bocquet. Both the genetic and morphological data support the recognition of Silene sunhangii as a distinct species, although there is inconsistency between these two datasets as to the relationships of the new species.

Prunus sunhangii: A new species of Prunus from central China.

Project description:A new species of Rosaceae from Central China, Prunus sunhangii D. G. Zhang & T. Deng, sp. nov. , is described and illustrated. The new species is placed in Prunus subgenus Cerasus by flower and fruit characteristics. It is most similar to Prunus cerasoides, but differs by having longitudinally 2-lobed apical petals, an acuminate leaf apex, 17-25 stamens, white petals, dark black drupes, brown hypanthium, and different phenology. The phylogenetic placement of this species was assessed based on morphological and molecular data. Molecular analysis (cpDNA + ITS) corroborated its placement in subgenus Cerasus, specifically Prunus section Serrula.

Ehrlichia species in pond-farmed leeches (Hirudinaria sp.) in Hubei Province, China.

Project description:Leeches are frequently used in traditional Chinese medicine. However, they are potentially hazardous to human and animal health by transmitting several pathogens. Studies of diseases transmitted by leeches are scarce. The purpose of this study was to analyze the pathogens carried in pond-farmed medicinal leech in China. Leeches were collected from 6 farms in Hubei Province in central China. DNA was extracted from the internal organ of leeches to analyze the origin of blood meal. Leech genera were confirmed through amplification of 18S rRNA and mitochondrial gene cytochrome oxidase I (COI) gene by PCR and host animal species were identified through amplification of mitochondrial cytochrome b gene. Species of Ehrlichia in the leech specimens were screened with PCR using specific primers. PCR amplification and DNA sequencing showed that 620 leeches were Hirudinaria sp. Ehrlichia DNA was detected in 39 specimens from 2 farms. We obtained a total of 65 sequences of the cytB gene from 620 leech internal organ samples including sequences of human (n = 5), rat (n = 1), domestic pig (n = 10), duck (n = 23), goose (n = 12) and buffalo (n = 14). Phylogenetic analysis of the rrs and groEL gene sequences showed that Ehrlichia detected in the study were closely related to Ehrlichia sp. in ticks from Korea and Japan. To the best of our knowledge, this is the first report on Ehrlichia DNA being detected from leeches. Our findings provided new data on Ehrlichia spp. and farmed leech species in China.

Veronicastrum wulingense (Plantaginaceae), a new species from Southwestern Hubei, China.

Project description:BackgroundThe genus Veronicastrum Heist. ex Fabr. are mainly distributed in East Asia, and only Veronicastrum virginicum (L.) Farw. is disjunctively distributed in eastern North America. The south area of China (extending to Taiwan Island) is the richest in Veronicastrum species. It is of medicinal importance in China as traditional herbs used to treat ascites diseases that caused by schistosomiasis. During field investigation of plant resources in Pingbaying National Forest Park, Southwestern Hubei, China, an unknown flowering population of Veronicastrum was discovered from thick humus layers adjacent to rocks under broad-leaved forests by walkways. They were collected and morphological characters assesed for further taxonomic treatment. Molecular analysis was also conducted to ascertain its phylogenetic position in the genus Veronicastrum.ResultsThis species is similar to Veronicastrum liukiuense (Ohwi) T.Yamaz. from the Ryukyu Islands, but can be distinctly differed by its axillary inflorescences (versus terminal on short leafy branches), pedicels up to 2.5 mm (versus sessile), corollas purple to purple-red (versus white tinged with pale purple) and florescence June to July (versus September to October). Also, phylogenetic studies showed the species was an independent clade in the genus Veronicastrum based on the maximum likelihood (ML) analyses using two different matrix sequences of concatenated molecular markers. The plastid genome of this new species is also reported in this study for the first time.ConclusionThe morphological and molecular evidences support the recognition of Veronicastrum wulingense as a new species.
