Abstract

Abstract: Primulina albicalyx, a new species of Gesneriaceae from Guangxi Zhuang Autonomous Region, SW China, is described and illustrated. This new species is similar to P. leprosa by its yellow flowers, white calyx lobes and large bracts, but can be easily distinguished from the latter by some qualitative and quantitative characters in the leaf blade, peduncle and corolla. The conservation status of P. albicalyx can be considered as Critically Endangered (CR) according to the IUCN Red List categories and criteria.

Highlights

The previously monotypic genus Primulina Hance (1883) has recently been redefined based on molecular data (Wang & al. 2011; Weber & al. 2011)

It displays a high degree of edaphic habitat specialization, i.e. the majority of species occur in karst limestone areas (Wang & al. 1990, 1998; Li & Wang 2004; Wei & al. 2010)
