Abstract

Hoya jianfenglingensis Shao Y. He & P. T. Li (Apocynaceae) is described as a new species from Hainan, China. The morphological characters of H. jianfenglingensis are illustrated and compared with the related species, H. fungii Merr. and H. carnosa (L. f.) R. Br. Hoya jianfenglingensis differs in its leaf indumentum, the prominent lateral veins in six to 10 pairs, the evident glands at the corona base, and the smaller corolla (only to 1.5 cm diam.). Hoya jianfenglingensis is assigned to section Hoya within the genus on the basis of the acute outer angle of the corona lobes.
