A treelet endemic to western Ecuador, where it grows in the coastal lowlands and the Andean foothills, in both primary and secondary forest. Reported as common in 1985 in the wet coastal forest of El Rosario, where it was known as "hueso de mono". That locale has since been inundated by the Daule-Peripa dam (C. Bonifaz, pers. comm.). Protected in the Reserva Ecológica Manglares-Churute and expected in the Reserva Ecológica Mache-Chindul. Dodson and Gentry (1991) reported the local extinction of the species in the Río Palenque private reserve. Apart from habitat destruction, no specific threats are known. Considered Endangered due to the drastic alteration of its habitat over the last 50 years.
