Abstract

A new species of Gesneriaceae, Primulina jianghuaensis K. M. Liu & X. Z. Cai, from a limestone cave in Hunan Province, China, is identified and described. Its seed and pollen grain morphology are described. The new species is morphologically closely related to P. lingchuanensis ( =Chiritopsis lingchuanensis) and P. danxiaensis ( =Chiritopsis danxiaensis), but it can be distinguished by its 12–25 (–30) leaves, ovate or broad ovate leaf blade, subcordate, truncate or slightly decurrent leaf base, undulate leaf margin, 5–20 cymes, and 2–3 staminodes.
