Primulina nana (Gesneriaceae), a new species from eastern Guangxi, China

Abstract

Primulina nana C.Xiong, W.C.Chou & F.Wen, a new species of Gesneriaceae from limestone areas of Guangxi, China, is described and illustrated here. It morphologically resembles P. yangshuoensis Y.G.Wei & F.Wen in papillose leaf surface, but can be easily distinguished from the latter by noting a combination of characteristics, especially in its leaf blades, leaf blade indumentum characteristic, calyx lobes, corolla and the disc. We found only one population at the type locality, about 200 mature individuals. According to the IUCN Red List Categories and Criteria (Version 3.1), the new species is provisionally assessed as Critically Endangered (CR).

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

“…Primulina plants prefer moist and sheltered environments such as caves, sinkholes, and cliffs (Xu et al 2021, Qin et al 2022, making the discovery of more species challenging. As field surveys increased in the hilly regions of south and southwest China, as well as northern parts of Vietnam, a number of new taxa withinPrimulina have been discovered and described (e. g. Ning et al 2014, Pan et al 2022, Su et al 2022, Xiong et al 2022, Xu et al 2023, Zhou et al 2023.…”
