Oxytropis shennongjiaensis (Fabaceae), a new species from Hubei, Central China.

ABSTRACT: Here we describe Oxytropis shennongjiaensis, a new species of Fabaceae from Central China (Hubei Province). Morphologically, O. shennongjiaensis is closely similar to O. sitaipaiensis, O. melanocalyx and O. kansuensis, but differs in stem characters, with less conspicuous internodes; persistent herbaceous stipules; pale yellow to white corolla; and stipitate legumes, 3-5 mm with a long beak. Phylogenetic analysis, based on the internal transcribed spacers (ITS) and two chloroplast markers (trnL-F and psbA-trnH), also identified O. shennongjiaensis as a new species, which is consistent with our morphological analyses. Considering the morphological data and phylogenetic data presented here, we believe that this evidence satisfies the required diagnostic criteria to identify O. shennongjiaensis as a new species.

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.

Diversity and distribution of Oxytropis DC. (Fabaceae) species in Asian Russia.

Project description:BackgroundThe dataset providing information on the geographic distribution of Oxytropis species on the territory of Asian Russia is discussed. The data were extracted from different sources including prominent floras and check-lists, Red Data books, published research on congeneric species and authors' field observations and mainly cover less-studied, remote regions of Russia. The dataset should be of value to applied, basic and theoretical plant biologists and ecologists interested in the Oxytropis species.New informationThe dataset includes 5172 distribution records for 143 species and 15 subspecies of genus Oxytropis DC. (Fabaceae Lindl.) in Asian Russia. The dataset fills gaps in the distribution of locoweeds in the study area and contains precise coordinates for many of rare and endemic species.

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.

Youngiahangii (Asteraceae, Crepidinae), a new species from Hubei, China.

Project description:Youngiahangii T.Deng, D.G.Zhang, Qun Liu & Z.M.Li, sp. nov., a new species of Asteraceae, is described and illustrated. It was collected in Wufeng County, Hubei Province, Eastern Central China. Youngiahangii is morphologically most similar to Y.rubida, but can be easily distinguished from the latter by capitula with 8-10 florets and the hairy leaf surface. Phylogenetic analyses, based on the internal transcribed spacers (ITS) and one chloroplast marker (rps16), showed that Y.hangii and Y.rubida were sister species with good support. The results of both phylogenetic analysis and the morphological data support the specific rank of Y.hangii.

Anthyllis apennina (Fabaceae), a new species from central Apennine (Italy).

Project description:A new species of Anthyllis endemic to central Apennine growing in dry pastures on limestone in the montane belt, within Abruzzo and Lazio administrative regions (central Italy), is here described and illustrated and the IUCN assessment is proposed. This new species belongs to the morphologically very variable Anthyllis vulneraria species complex and it is close to A. pulchella (south-eastern Europe and Caucasus), but it can be clearly distinguished by its smaller flowers, mainly light yellow-coloured, bracts longer than flowers, calyx pink-coloured (usually only at apex) and size of cauline leaves and leaflets. Furthermore, the name A. pulchella is here lectotypified, by a second-step typification, on a specimen preserved at PAD.

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

Project description: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.

Phylogenetic study of the endemic species Oxytropis almaatensis (Fabaceae) based on nuclear ribosomal DNA ITS sequences.

Project description:BACKGROUND:Oxytropis almaatensis Bajt. is a rare, narrow endemic species of the Trans-Ili Alatau mountains in Kazakhstan. Up to now, no studies regarding the taxonomy and variation of key morphological traits of O. almaatensis were undertaken. The purpose of this analysis was to evaluate phenotypic variation of O. almaatensis and assess the position of the species within the genus based on nucleotide sequences of the nuclear ribosomal DNA internal transcribed spacer (ITS) region. RESULTS:Two populations of O. almaatensis were collected in neighboring gorges of the Trans-Ili Alatau Mountains. The ITS sequences from the samples of two populations of O. almaatensis were identical. The phylogenetic analysis indicated that O. almaatensis is within Oxytropis genetically close to O. glabra as these species formed a separate subclade. The phenotypic variation of populations was assessed using nine morphological traits and compared to descriptions of O. glabra. The range of variation for the traits between two populations was established. A clear morphological difference of O. almaatensis and O. glabra was found in peduncle length to leaf length ratio. This was in O. almaatensis 1.56, while in O. glabra, it was 1.0. CONCLUSIONS:The study provides the first phenotypic description and phylogenetic placement of the rare endemic species O. almaatensis. The morphological traits in two O. almaatensis populations showed a high level of phenotypic variability. Although clearly different from O. glabra, the ITS phylogeny grouped these species in a subclade within the genus.
