Primulina magnifica (Gesneriaceae), a new species from northern Guangxi, China

Primulina magnifica F.Wen & W.C.Chou, a new species of Gesneriaceae from the limestone areas of Yizhou District, Hechi City, Guangxi, China, is described and illustrated here. It morphologically resembles P. mollifolia (D.Fang & W.T.Wang), J.M.Li & Yin Z.Wang in leaf blades. Still, it can be easily distinguished from the latter by noting a combination of characteristics, especially in its tube infundibuliform, and obviously broader bracts. We found only one population, about 300 mature individuals, at the type locality. According to the IUCN Red List Categories and Criteria (ver. 3.1), the new species is tentatively designated as Critically Endangered (CR).
