Abstract

Two new species of Matelea (Apocynaceae: Asclepiadoideae, Gonolobinae) are described from northern South America: M. fontana and M. pacifica. The species belong to the Ibatia-Matelea complex, but exhibit distinct differences in floral characters from previously known taxa, including the structure of gynostegial coronas. A key and descriptions to members of the northern South American and West Indian Ibatia-Matelea complex is provided, including M. cumanensis, M. maritima, and M. rubra. Asclepias maritima, Cynanchum fimbriatum, and Ibatia muricata are lectotypified.
