Artemisiaqingheensis (Asteraceae, Anthemideae), a new species from Xinjiang, China.

ABSTRACT: Artemisiaqingheensis (Asteraceae, Anthemideae), a new species from Qinghe County, Xinjiang, China, is described and illustrated. We investigated its phylogenetic position and relationships with 35 other species of Artemisia using whole chloroplast DNA sequence data. The molecular phylogenetic results and morphological evidence (multi-layered involucral bracts and homogamous capitula with bisexual flowers) showed that the new species belongs to ArtemisiasubgenusSeriphidium. A diagnostic table and discussion of morphological characters are provided to distinguish the new species from A.amoena, A.gracilescens, A.lessingiana and A.terrae-albae.

Ajaniaflavida (Asteraceae, Anthemideae), a distinct new species from southwestern China.

Project description:Ajaniaflavida, a new species from western Sichuan and eastern Xizang, China, is described and illustrated. It is readily assigned to A.sect.Ajania owing to its straw-colored, glossy involucres and marginally whitish scarious phyllaries. Within the section, it is distinct in being a shrub of 1-2 m in height, and in having creamy yellow florets. It is superficially similar to A.ramosa in A.sect.Phaeoscyphus, but can easily be distinguished by, among other characters, the plant height, color of the florets and margins of the phyllaries. In addition, we provide a distribution map of the new species.

Artemisiacalcicola (Asteraceae, Anthemideae), a new species from karst region in Guizhou, southwestern China.

Project description:Artemisiacalcicola (Asteraceae, Anthemideae), a new species from karst region in Shibing county, Guizhou province, southwestern China, is described and illustrated. The species can be readily assigned to A.subg.Artemisia in having fertile disk florets and glabrous receptacles. Within this subgenus, A.calcicola is distinguished by having (2- or) 3-pinnatipartite leaves and narrowly ellipsoid involucres 0.9-1.3 mm in diameter. It resembles A.annua to some extent, but differs immediately by the plant duration, stem and leaf indumentum, and involucre shape and size. A detailed description and distribution map of this species are also provided herein.

Ainsliaea daheishanensis (Asteraceae): a new species from China.

Project description:In this work, we describe a new species, Ainsliaea daheishanensis Y.L.Peng, C.X.Yang & Y.Luo, based on morphological traits. The new species was discovered in the mountains of Yunnan, near the border between Myanmar and China. The new species differs from the phenotypically closely-related Ainsliaea foliosa Handel-Mazzetti in the morphology of the leaf veins and phyllaries, those having a protruding abaxial reticulate pattern in the lower and median part of stem with white hairs and narrow inner phyllaries. A key to the three closed Ainsliaea species occurring in China is provided.

Hieracium sinoaestivum (Asteraceae), a new species from North China.

Project description:Hieracium sinoaestivum Sennikov sp. nov. is described as new to science and illustrated. This presumably apomictic species is solely known from two old collections made in a single locality in the Shanxi Province of China. It belongs to the hybridogenous group Hieracium sect. Aestiva (Hieracium sect. Prenanthoidea × Hieracium sect. Umbellata) and is most similar to Hieracium veresczaginii from southern Siberia. The new species occurs at low altitudes in the forest belt of Lülian Mts. and belongs to taiga forest elements.

Sinosenecioyangii (Asteraceae), a new species from Guizhou, China.

Project description:A new species Sinosenecioyangii D.G. Zhang & Q. Zhou (Asteraceae, Senecioneae) from Guizhou Province, China, is described and illustrated based on its morphological characteristics and molecular evidence. It closely resembles S.confervifer and S.guangxiensis, the former in the scapigerous habit and smooth and glabrous achene surface, the latter in the calyculate involucre and purple abaxial leaf surface, and both in the shape and indumentum of leaf lamina, but differs markedly from the latter two in having fewer capitula and epappose achenes. Phylogenetic analysis based on nrITS and ndhC-trnV sequences shows that this new species belongs to the S.latouchei clade and is sister to S.guangxiensis with moderate support.

Senecio changii (Asteraceae: Senecioneae), a New Species from Sichuan, China.

Project description:Senecio changii (Asteraceae: Senecioneae), a new species from Muli, Sichuan, southwestern China, is described. It is distinguished in Chinese Senecio s.s. by having lyrate-pinnatisect to pinnatisect leaves and a single terminal large discoid capitulum which is somewhat nodding. Evidence from floral micromorphology, karyology and molecular phylogenetic analyses based on the nuclear ITS/ETS sequence data all support its membership within Senecio s.s.

Project description:Onosma fuyunensis, a new species of Boraginaceae from northern Xinjiang, China, is described and illustrated here. Onosma fuyunensis is similar to O. simplicissima and O. gmelinii; it differs in having a particularly bristly indumentum, unbranched stems, white and yellow corollas, anthers united only at base, and nutlets with a stipitate cicatrix. An updated key to the species of Onosma from Xinjiang and Altai Mountains is also provided.

Asterquanzhouensis (Asteraceae), a new riparian species from eastern China.

Project description:Asterquanzhouensis sp. nov. (Asteraceae) from Fujian, eastern China, is described and illustrated. It grows on rocks in the riparian zone. Morphological, cytological and molecular investigations of A.quanzhouensis were carried out. The morphological data and phylogenetic analysis based on combined ITS, ETS and trnL-F dataset suggest that A.quanzhouensis is a separate species closely related to A.tonglingensis. The new species differs from the latter by the shorter stem length, leaf morphology, colour of phyllaries, number of ray florets, and achene shape. The cytological observation shows that the new species is diploid with a karyotype of 2n = 18.

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.
