ABSTRACT

We describe a new species of Gesneriaceae,Didymocarpus sinoindicus N.S.Prasanna, Lei Cai & V.Gowda from India and China with detailedmorphological description, diagnostic characters,illustrations, and colour photographs. The new speciesis morphologically similar to D. oblongus Wall. exD.Don, D. hookeri C.B.Clarke, and D. adenocalyxW.T.Wang, but can be easily distinguished from themby its emarkable creamy-white to greenish-yellowsepals and petals and characteristic purple striations oncorolla lobes.
