Kidyoo, Manit; PALIYAVUTH, CHANITAA new pendulous herb, Ceropegia thaithongiae Kidyoo (Apocynaceae, Asclepiadoideae), is described from northern Thailand. This plant is strictly endemic to Chiang Dao Wildlife Sanctuary and critically endangered owing to its living in an ecosystem affected by frequent natural disturbances. It is here described, illustrated and compared to the similar species, C. mairei. Both species have fusiform rootstocks, 1-2-flowered cymes, deeply bifid outer corona lobes and linear, hairy inner corona lobes. However, the new species can be clearly distinguished by its glabrous stem, leaf covered with hairs on both surfaces and glabrous corolla tube and lobes.
