摘要：

Changes in succulent Cynanchum I., species are needed for the Flora of somalia account of Apocynaceae subfamily Aselepiadoideae. The following changes are proposed within the tribe Asclepiadeae, subtribe Cynanchinae, Cynanchum riminale subsp. crassicaule, another subspecific taxon in the C. riminale complex, is described as new, based on morphological, ecological, and molecular evidence. Its chromosome number is specified with 2n = 22. The new combination Cynanchum riminale subsp. stipitaceum is proposed, and Sarcostemma andongense Hiern is recognized as a new synonym of C. riminale subsp. stipitaceum.
