Justification:
Assessed as Data Deficient in 1997, this species is here reassessed based on improved information.

A shrub or tree endemic to the wet coastal forests of Ecuador. Its name suggests that the species also occurs in Peru (previous entries of this species in the Red List have recorded it as a Peruvian species) and it appears in Brako and Zarucchi’s 1993 catalog of Peruvian plants. However, it seems that this is due to a mistake in the original Ruiz y Pavón collection label.

Currently known from four subpopulations on the central Ecuadorean coast. The first is in the Jauneche private reserve, where it is very common within primary and secondary forest (Gentry (1986) reports 36 individuals > 2.5 cm dbh in 0.1 ha). The second is 39 km northeast of Balzar and the third in El Barro, 6 km from Quevedo and currently flooded by the Daule-Peripa dam (C. Bonifaz, pers. comm.). Valverde (1991) reports a fourth subpopulation in secondary forests of the Cordillera de Chongón Colonche, in Cerro Vacas Muertas. None of these populations are inside Ecuador’s protected areas network. The principal threats are deforestation and conversion of coastal forest to croplands over the last 50 years. Habitat destruction is the only known threat to the species.
