Didymocarpus sinoindicus (Gesneriaceae), a new species from India and China

Abstract

We describe a new species of Gesneriaceae, Didymocarpus sinoindicus N.S.Prasanna, Lei Cai & V.Gowda from India and China with detailed morphological description, diagnostic characters, illustrations, and colour photographs. The new species is morphologically similar to D. oblongus Wall. ex D.Don, D. hookeri C.B.Clarke, and D. adenocalyx W.T.Wang, but can be easily distinguished from them by its remarkable creamy-white to greenish-yellow sepals and petals and characteristic purple striations on corolla lobes.
