Inflorescence below emerging leaves, stalk 9-12 cm in length, bract 50-80 cm long, 8-11 cm long rachis with rachillae 79-120 50-64 cm long; flowers in triads, or pairs lonely, the male 4-5 mm in length, the female 4 mm in length, yellowish white. Fruits globose to ellipsoid, 2-3 cm long and 1.5-2.5 cm in diameter, purplish black when ripe. Editing by edric.
Understorey or subcanopy palm. Stems clustered, often numerous, to 15 m tall and 10-20 cm in diameter. Leaves spreading, about 5 m long, forming a globose crown; pinnae 50-100 on each side, more or less horizontal, regularly inserted, or in the central part of the blade arranged in groups of 2-4, usually paler below than above, the central ones to 1 m long. Inflorescence once branched, with a short rachis, and numerous pendulous, to 70 cm long branches. Fruits elongate or ovoid, purple when ripe, pointed at apex, 2-3 cm long.

Sunny, moist, well drained position. Very good in cultivation, and deserves to be much more widely grown. Appears to be reasonably drought tolerant, but probably not very cold tolerant however.
Comments and Curiosities
Uses: The main use of this species is food. The fruits are eaten after cooking mild and used for the production of juices or beer; oil is also extracted from them. The fresh buds can be eaten raw or cooked. The stem is occasionally used as a column or beam in construction. The principal source of wood used in the manufacture of small bows and arrows sold to tourists. Trunks used as house posts.. The rachis and pinnae are used in making baskets: in some indigenous communities in the area of Nariño, the leaves jaibaná used to call the spirits during rituals or dances. This palm is also used by the indigenous in feedlots for hunting.
The fruits of this palm are similar in many respects to those produced by Oenocarpus bacaba and O. distichus, but O. mapora can be easily distinguished from its cousins because it tends to form clumps along river and stream banks and the trunks are much more slender. It is hard to distinguish “natural” stands of the palm from those that have arisen from discarded seeds or plantings around rural houses. Oenocarpus mapora is found in central and western Amazonia and reaches north into Venezuela and parts of Central America. The fruits are gathered to make a much appreciated juice. Since the trunk has no spines, people either shimmy up the trunk to gather the fruits or use a ladder. Children use catapults to knock down the fruits. The sturdy trunks are used for posts and flooring in some areas and the trunks of young specimens were once used to fashion blowguns. (Dr. Nigel J.H. Smith)
