Distribution:— The most widespread species in the western Andes and Central America ( Fig. 12). It is distributed from Nicaragua through Costa Rica and Panamá, along both the Caribbean and Pacific coasts and then in the western part of Venezuela and all of the Colombian and Ecuadorian Chocó, reaching southwestern Ecuador in El Oro, 0–2000 m elevation.

Conservation status:— Not evaluated.

Notes:— This species has a great morphological variation. Specimens from Colombia and particularly from Ecuador have more pubescent leaves than those from other parts of its distribution. Collections from Central America generally have fewer secondary veins and smaller fruits with thinner pericarp than those from South American.

Its latex is watery and red. In living plants, leaves are ferruginous or whitish below, flowers green-yellow and fruits green with a white or red aril. Its wood is used for indoor construction in Colombia and boxes in Ecuador. Oil extracted from its seed is eaten, sold on the market or used medicinally to treat skin parasites and skin infections of domestic animals ( Schultes & Holmstedt 1971).

Vernacular names:— Fruta dorada, sebo, níspero ( Costa Rica); saba, bogamani verde, roble, white cedar, miguelario, wine wood ( Panama); soto ( Colombia); aral ami teiug, awepit, cuangaré, cuangaré indio, mujchi, sangre de gallina ( Ecuador); otuba medicinado ( Venezuela).
