A new species of Primulina (Gesneriaceae) from Guangdong, China

A new species of Gesneriaceace, Primulina yangchunensis, is described and illustrated from China. The species is related to P. orthandra, but it can be easily distinguished by its leaf blade base cuneate, margin entire and rugose, both surfaces hispid, longer bracts broadly lanceolate, 1–2 cm long, and the length of the abaxial lip obviously longer than that of the adaxial one. The conservation status of this new species was assessed as “Critically Endangered” (CR) according to IUCN Red List Category and Criteria.
