Philibertia includes 38 species of herbs and climbing perennials with opposite leaves, usually with long petioles and heart-shaped to lanceolate. Shoots range from smooth to pubescent or hairy with white latex sap smelling of garlic. Umbels of yellow or purplish flowers arise from leaf nodes.
Philibertiae are distributed from Florida and Texas to California in N. America and Argentina, Bolivia, Brazil, Chile, Ecuador, Paraguay, Peru, Uruguay in S. America. Philibertia has sometimes been included under Sarcostemma, particularly the N. American species, although Sarcostemma species have leafless stems.
