Abstract

Didymocarpus nautiyalii M.Khanal, D.Borah & Dev.Kumar (Gesneriaceae) is described as a new species from Shi-Yomi District, Arunachal Pradesh, Northeast India. It resembles D. albiflorus Souvann. & Phonep. in its habit, leaves, few-flowered inflorescences and slightly pouched infundibuliform corolla with an expanded mouth, but differs in its much shorter stem, sessile to very short petioles, coriaceous lamina, 1–3-flowered cymes, smaller campanulate calyx, shorter bluish-purple corolla, and a glabrous ovary. The species is assessed as Data Deficient according to the IUCN Red List criteria.
