Abstract


A species of the essentially Sino-Himalayan genus Didymocarpus (Gesneriaceae), D. medogensis, described in 1982 from China/SE Xizang (SE Tibet), is newly recorded for India. Since its establishment, the species remained very little known. A full documentation, including an updated description based on living plants and colour photographs of plants in their natural habitat, as well as photographs showing flower and fruit details, is therefore presented here. In India, the plants of D. medogensis were spotted in two localities, one in the Shi Yomi district and the other in the Lower Dibang Valley districts of Arunachal Pradesh. Slight morphological differences in the populations demonstrate that the plants are in the process of active evolutionary diversification.
