- Oenocarpus bataua var. oligocarpus (Griseb. & H.Wendl.) A.J.Hend. - Trinidad, Venezuela, Guianas
It is usually found in sandy soils with a high organic matter content that are subsequent to flooding, possibly because there are few other species which compete with it. It can grow extremely well on unflooded soils as witnessed by high-density stands in the pastures of the Colombian Chocó, though it is rarely found on terra firma in the wild since competition from other species is such that it rarely gets the high light levels it needs to set fruit.
Its stem is solitary, erect, 10–25 m (33–82 ft) in height and 2–3 dm (8–12 in) diameter, smooth, and ring-shaped. It has 10–16 leaf terminals, petiole 10–50 cm, rachis 3–7 m long; with leaflets up till 2 m long and 15 cm breadth, approximately 100 to each side, placed in the same plane.
Patawa fruits are a resource for cosmetics, food and pharmaceuticals purposes.
