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.

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.

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.

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.

Reinstatement of the corticioid genus Leifia (Hymenochaetales, Basidiomycota) with a new species L.brevispora from Hubei, Central China.

Project description:The monotypic genus Leifia was previously considered to be a later synonym of Odonticium. With the morphological and phylogenetic evidence provided by an additional four East Asian specimens, we propose to reinstate Leifia as an independent genus in Hymenochaetales. Leifia morphologically differs from Odonticium by its grandinioid hymenophore with hyphal strands, numerous thick-walled cystidia with an invaginated apical end and narrowly and thick-walled basidia. The phylogeny generated from the current data set of ITS and 28S regions indicates that Leifia forms a sister clade to Odonticium. Besides the generic type Leifiaflabelliradiata in the Leifia clade, two specimens, collected from Hubei, Central China, are newly introduced as Leifiabrevispora. This new species is the second species of Leifia and differs from the generic type by its shorter basidiospores and distribution in warm-temperate to subtropical areas in East Asia. The additional two specimens, collected from Da Lat, Viet Nam, differ morphologically, both from each other and from known species of Leifia, but more samples need to be examined before further taxonomic decisions can be made.

Isolation and characterization of microsatellite loci from Oxytropis diversifolia (Fabaceae).

Project description:Premise of the Study:Microsatellite primers were developed for a perennial legume from northern China, Oxytropis diversifolia (Fabaceae), to investigate population genetic structure of this taxon, as well as potential hybridization events with closely related taxa in this genus. Methods and Results:One hundred and five primer pairs were designed from Illumina sequence data and screened for suitability. Fifteen of these primer pairs were polymorphic, and these primers amplified tri-, tetra-, and pentanucleotide repeats with 10-56 alleles per locus. Cross-amplification tests in three other Oxytropis species from northern China (O. leptophylla, O. neimonggolica, and O. squammulosa) revealed that all of these loci can be amplified successfully and show polymorphism. Conclusions:These primer pairs can be used to assess the genetic diversity and population structure in future studies of O. diversifolia, as well as studies of potential hybridization events with closely related taxa in this genus.
