The name is derived from the Greek words σαρκὸς (sarkos), meaning "flesh," and στέμμα (stemma), meaning "garland".[2] Members of the genus are known generally as climbing milkweeds or caustic bushes. They are found across Africa and tropical Asia, in Australia, and in parts of North America. These plants are perennial flowering shrubs with trailing vines or lianas. They are often adapted to heat and/or desert conditions. Some have few or no leaves and photosynthesize in the tissues of the green stems. The soft stems are filled with a milky white latex that is poisonous and caustic in some species. The flowers have a ring of thick tissue at the base which extends into hollow spherical appendages within the flower corolla. TaxonomyThe taxonomic status of this genus is contested. The genus Sarcostemma has been shown to be nested within the genus Cynanchum, and in 2012 Sarcostemma was put into synonymy with Cynanchum.[3][4] Thus Sarcostemma viminale has been renamed Cynanchum viminale. However this change has not been accepted by all taxonomists and the name Sarcostemma remains in use by a minority.[5]
