摘      要：A single small population of chasmophytic plants is described as Mojiangia oreophila,a monotypic genus in the subtribe Crepidinae,characterised by a unique combination of morphological features,in particular densely long-papillose homomorphic achenes with five main ribs each accompanied by two secondary ribs,coarse brownish pappus bristles,moderately many-flowered capitula,a small involucre with numerous outer phyllaries,perennial rosette herb growth and brown-woolly caudex and leaf *** phylogenetic analysis detected that in the nrlTS phylogeny *** forms a clade of its own in the Crepidinae;in the plastid DNA phylogeny it is nested in the clade formed by the hybrid-ogenous genus Faberia,the maternal ancestor of which comes from the Crepidinae and the paternal ancestor from the Lactucinae,where Faberia is placed in nrlTS *** shares several morphological features with Faberia and also shares the expected chromosome number of 2n=16 with its hitherto unknown maternal *** may therefore be a successor of the maternal ancestor of ***,cytonuclear discordance is to be assumed in Mojiangia,caused by chloroplast capture as a result of hybridisation and introgression with Faberia.
