Oreocharis × qianshanensis (Gesneriaceae), a new natural hybrid from Qianshan City, Anhui, China

PhytoKeys 225: 41–51 (2023)

ABSTRACT

Oreocharis × qianshanensis, a new natural hybrid that belongs to Gesneriaceae, is described and illustrated. Morphological evidences hint it is an interspecific hybrid of O. auricula and O. chienii. Further, molecular studies also showed that O. × qianshanensis arose from a hybridization between the maternal O. auricula and the paternal O. chienii. In this report, the morphology, chloroplast genome, and geographic distribution of O. × qianshanensis are documented.
