Abstract

A new species of Primulina, P.pingnanensis, from the Guangxi Zhuangzu Autonomous Region, China, is described and illustrated here. It is morphologically similar to P.orthandra but has significant differences in the bracts, corolla tube and lobes shape, as well as in the indumentum of the outer surface of the corolla, the filaments, the staminodes and the anthers. Colorful photographs and essential information of this new taxon are also provided, including detailed taxonomic description, distribution, habitat, the comparison table, and the IUCN conservation status. We also discuss a validation of new combination P.crassifolia and Chiritacrassifolia.

Keywords: Flora of Guangxi; Gesneriaceae; Primulinaorthandra; limestone flora; new taxon; taxonomy.
