“…China has over 123 accepted names of Aster (Chen et al 2011) and its southwest region is the distribution centre of this genus (Li et al 2012). In China, eight new Aster species have been described the last five years (Zhang et al 2015, 2019, Li et al 2017, 2020, Xiao et al 2019a, b2019b, 2020, Xiong et al 2019).…”

China, is described, illustrated and compared with related taxa based on evidence from morphology and molecular phylogeny. Morphological observations have shown that A. sanqingshanica is most similar to A. tianmenshanensis, but readily differs by its ascending stem (versus erect), marcescent basal leaves (versus deciduous), ciliate basal leaf margins (versus glabrous), 4-5-seriate phyllaries (versus 2-3-seriate), purple phyllaries (apex) (versus green), flat receptacle (versus convex) and broader lamina of the ray florets (3-4 mm versus 2-3 mm). Phylogenetic analysis based on nrDNA ITS and ETS sequence data show that A. sanqingshanica is closely related to A. tonglingensis.

Aster quanzhouensissp. 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.
