Primulina jiuyishanica K. Liu, D.C. Meng & Z.B. Xin, a new species of Gesneriaceae from Hunan, China, is described and illustrated. The new species is morphologically similar to Primulina fimbrisepala (Hand.-Mazz.) Yin Z. Wang, but differs in its elliptic to broadly elliptic leaf blade with broadly cuneate base, peduncle densely pubescent with spar...

... As of February 2022, there were 221 species (excluding infraspecific taxa) (GRC 2022) in this genus. China is the centre of diversity for Primulina with at least 204 species and 15 varieties occurring there at present (Wen et al. 2022), especially in limestone areas (Wei 2018;Wen et al. 2019;Ge et al. 2020;Liu et al. 2020;Xin et al. 2020aXin et al. , b, c, 2021Zhang et al. 2021). The tropical and subtropical karst limestone mountainous areas of Guangxi, China, are the centres of species diversity and differentiation of this genus . ...
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).

China is the centre of diversity for Primulina with at least 183 species and 27 varieties occurring there at present, especially in limestone areas (e.g. Wei 2018;Wen et al. 2019Wen et al. , 2021Ge et al. 2020;Liu et al. 2020;Xin et al. 2020a, b, c).

Primulina papillosa Z.B. Xin, W.C. Chou & F. Wen, a new species from limestone areas of Guangxi, China, is described and illustrated here. It morphologically resembles P. linearifolia (W.T. Wang) Yin Z. Wang and P. pseudolinearifolia W.B. Xu & K.F. Chung, but can be easily distinguished by some combined characters, especially its leaf blades densely papillose-hispid. We found only one population at the type locality with no more than 200 individuals, so that this new species is provisionally assessed as Critically Endangered (CR) using IUCN Criteria.
A new species, Primulina cataractarum (Gesneriaceae) from limestone areas in southern Hunan, China, is described and illustrated with photographs based on morphological and molecular data. This new species is slightly similar to P. porphyrea and P. rubribracteata in morphology, but it can be easily distinguished by its smaller rounder leaves, large repand green bracts and purple corolla tube. Phylogenetic analysis proved that these three species are different, and their relationships are relatively distant. It also reveals that P. cataractarum is genetically similar to P. jiangyongensis, which is geographically next to the type locality of the new species, but they differ greatly in morphology. Following the IUCN Red List Criteria, P. cataractarum is assessed as Critically Endangered (CR B2a; C2b) because of its limited populations and vulnerable habitat.
