Abstract

Hoya nyingchiensis Y.W.Zuo & H.P.Deng, sp. nov. from Nyingchi, Tibet Autonomous Region (China), is described, illustrated and compared with related species. H. nyingchiensis appears to be related to H. chinghungensis, H. bella and H. kingdonwardii due to the similar growth habit, but it can be easily distinguished by the shape of leaves, leaf surfaces, inflorescence, calyx, corolla structure and corona shape.
