Three small South American genera of Apocynaceae-Asclepiadoideae are included in a phylogeny of South American Apocynaceae-Asclepiadoideae using the trnT – L and trnL – F intergenic spacers and the trnL and rps16 introns. Two genera, Widgrenia and Rhyssostelma , are nested in the large genus Oxypetalum . One, Stenomeria , is congeneric with Tassadia . The correspondent and necessary new combinations, Oxypetalum nigricans and O. corymbosum , and Tassadia decalepis, T. fosteri and T. pentalepis are made. The new combination Tassadia guanchezii is proposed for a hitherto insufficiently known species of white sand savannas of Colombia and Venezuela. Lorostelma struthianthus , a synonym of Tassadia decalepis , is lectotypified. This manuscript proposes taxonomic changes that reflect advances in Oxypetalinae and Tassadiinae, and it emends the description of Tassadia guanchezii .
