(Crepidinae, Cichorieae, Asteraceae), a new species and genus from Mojiang County, SW Yunnan, China, and putative successor of the maternal ancestor.

A single small population of chasmophytic plants is described as 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 axils. Molecular phylogenetic analysis detected that in the nrITS phylogeny forms a clade of its own in the Crepidinae; in the plastid DNA phylogeny it is nested in the clade formed by the hybridogenous genus the maternal ancestor of which comes from the Crepidinae and the paternal ancestor from the Lactucinae, where is placed in nrITS phylogenies. shares several morphological features with and also shares the expected chromosome number of 2n = 16 with its hitherto unknown maternal ancestor. may therefore be a successor of the maternal ancestor of . Alternatively, cytonuclear discordance is to be assumed in , caused by chloroplast capture as a result of hybridisation and introgression with .
