Abstract

A new species from Phu Chong-Na Yoi National Park, Ubon Ratchathani Province, eastern Thailand, Ceropegia phuchongensis Kidyoo & K. Suwann. (Apocynaceae, Asclepiadoideae), is described, illustrated and compared with the related C. tenuicaulis Kidyoo. The new species differs in corolla tube shape, color and trichomes inside the corolla tube, as well as pollinium and corpusculum shape. In addition, the gynostegium surfaces of the two species also support the distinctiveness of the new species.
