Abstract
A new species of Gesneriaceae from eastern Nepal, Didymocarpus nepalensis Bh.Adhikari & Mich.Möller is described and illustrated. It is morphologically most closely allied to D. cinereus D.Don but differs by its well-developed stem, the absence of basal leaves and less deeply divided calyx. A detailed description, colour photographs, line drawings are provided and the morphological differences of relevant species are discussed.

Didymocarpus nepalensis Bh.Adhikari & Mich.Möller, sp. nov. 

 Didymocarpus nepalensis is most similar to D. cinereus but can be distinguished by the absence of basal leaves (vs. present), inflorescences shorter than the stems (vs. equal to longer) and calyx lobes 1/4–1/3 of the calyx tube (vs. half or more than half).
