Collected only once on the island and not seen in recent years. Elsewhere in Panama, flowers principally from April to July, with the fruits developing quickly and appearing most abundantly in July.

Mexico to Peru and Brazil; West Indies. In Panama, ecologically variable; known from tropical moist forest in the Canal Zone, Veraguas (Coiba Island and Santiago), and Panama, from premontane dry forest in Panama (Taboga Island), and from premontane wet and lower montane wet forests in Darien (Cerro Pirre). It appears likely that the species will be found to occur in tropical wet forest as well.
