Primulina jiuyishanica (Gesneriaceae), a new species from Hunan, China

Abstract

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 sparse glandular hairs, corolla throat with no purple spots inside, the yellow patch in the throat densely glandular-pubescent and pistil densely glandular-pubescent. Photographs and descriptions of the new species are provided below.

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

“…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 (Li et al 2019).…”

Primulina papillosa (Gesneriaceae), a new species from limestone areas of Guangxi, China

“…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 2019 , 2021 ; Ge et al 2020 ; Liu et al 2020 ; Xin et al 2020a , b , c ). The tropical and subtropical karst limestone mountainous areas of Guangxi are the centres of species diversity and differentiation of this genus ( Li et al 2019 ).…”
