Vincetoxicum gongshanense Wen B. Xu & J. Y. Shen (Apocynaceae), a new species from Gongshan County, Yunnan, China, is described and illustrated. It is similar to V. silvestre (Tsiang) Meve & Liede, V. kerrii (Craib) A. Kidyoo and V. biondioides (W. T. Wang) C. Y. Wu & D. Z. Li, but can be distinguished by the leathery leaves, five basal veins, ovate-triangular sepals, yellow corolla, lanceolate corolla lobes, wide triangular corona and reniform pollinia. Photographs, line drawing, distribution, comparison with related species, and a parallel conservation assessment are provided for this species.
