Justification

A vine or liana endemic to Ecuador, where it is known from two old collections made 300 km and thirty years apart. One was made in Balao, Guayas province, by H. Eggers in 1892; the other along a forest edge in Tandapi, Pichincha province, by Heilborn in 1920. The Tandapi subpopulation may persist inside the nearby Reserva Ecolgica Los Ilinizas. Habitat destruction is the only known threat to the species. Like many vines, it may persist or thrive in disturbed habitats.
