Abstract
Hoya tengchongensis, a new species of Apocynaceae, subfamily Asclepiadoideae from Yunnan, China, is described and illustrated. The new species is morphologically similar to Hoya serpens in its creeping habit, bearing small and suborbicular leaves, and adaxially tomentose corolla. However, H. tengchongensis differs from H. serpens in corolla size (ca 7 mm versus ca 12 mm in diam) and corona morphology (corona lobes slightly ascending versus erect).
Keywords: Hengduan Mountains, Hoya serpens
