Abstract

The polyphyly ofSarcostemma sensu latu, suspected on morphological and karyological reasons is confirmed by analysis of thetrnL-F spacer region. With the exception ofCynanchum montevidense (subgen.Mellichampia, Sundell 1981), Old World and New World taxa belong to different clades.Sarcostemma sensu stricto andPlatykeleba show a strong affinity to Old WorldCynanchum; the affinities ofOxystelma cannot be determined at present.Philibertia andBlepharodon are sister groups, both are sister toFunastrum, andPentacyphus is basal to the New World clade.
