Symbiezidium barbiflorum (Lindenb. & Gottsche) A.Evans, a species widespread in the Neotropics, is discovered at the east coast of Madagascar. The identification is based on its winged and randomly laciniate perianth and its U shaped underleaf insertion, which well distinguishes it from the already known endemic S. madagascariense Steph. Otherwise S. barbiflorum is a new example of Afro-American disjuncts, which do not occur in continental Africa.
