摘要：
Oxypetalum habrogynum and O. helios, two new species of Asclepiadoideae, Apocynaceae, are described and illustrated. Oxypetalum habrogynum has the membrane of the caudicles of the pollinarium concave and not convex or plane as in other species. Oxypetalum helios has the segment of the Corona 3-lobed, lacking an adaxial appendage, and the gynostegium apex is filiform and bifid at its distal third. These species are endemic to the National Park of the Serra da Canastra in the state of Minas Gerais, Brazil.
