Abstract
A new species of the genus Trichosanthes (Cucurbitaceae), T. napoensis, is described and illustrated from Guangxi Province, western China. It is closely related to T. pedata Merr. & Chun, but it can be distinguished from the latter by having 3-fid tendrils, a fruit apex with a prominent protrusion, and oblong-elliptical seeds with a ridge at the margin.
