Abstract

A newly discovered species from central Laos, Ceropegia longicaudata, is here described and illustrated. It is compared with the morphologically similar species Ceropegia cochleata Kidyoo. Ceropegia longicaudata displays clear differences in the leaf pubescence and venation, length of the corolla lobe tips, colour of corolla lobe, and shape of staminal corona lobes. Ceropegia cochleata is newly recorded for the Flora of Laos. A key to the now three species of Ceropegia in Laos is also provided.
