    Abstract

    Primulina longanica F.Wen & W.C.Chou, a new species of Gesneriaceae endemic to Guangxi, China, is described and illustrated. The new species is morphologically similar to P. yangshuoensis F.Wen & Y.G.Wei, but differs in several key characteristics, including the presence of stolons, indumentum of petiole, peduncle, filament, ovary, and style, bract shape, and corolla length. The species is currently known only from its type locality, in Long’an County, Guangxi, where it grows on limestone cliffs in a subtropical monsoon climate area. Due to its limited distribution and over-collection for ornamental purposes, P. longanica is provisionally assessed as Critically Endangered (CR) according to the IUCN Red List Categories and Criteria.
