Western Amazon region in Colombia (Amazonas, Caquetá, Guainía, Guaviare, Vaupés), Venezuela (Amazonas, Bolívar), Peru (Loreto), and Brazil (Amazonas); open or dwarf forest in wet, poorly drained areas on whitesand soil and black-water drainage areas below 350m m; also in similar habitats in the southwestern Guayana Highland region of Venezuela (Amazonas, Bolívar) in open cloud forest 1100-1500 m.
Fruits are eaten by oilbirds (Steatornis caripensis), which seem to be an important disperser of this species (Galeano, pers. obs.). (Gloria Galeano & A. Henderson: Flora Neotropica, Monograph 72)A


  • Spruce (1871) wrote: " It varies so much in the quality of the fruit that, were not all esential characters the same, it might be supposed to include two or more species; for in certain districts the mesocarp of the fruit , though thin, is soft and sweet, amd makes a better drink than even the common Assai or Manaca (E. oleracea); but where the palms grow on almost bare flats of granite rock that are inundated with every shower, the pulp is so grumous or gritty as to be unserviceable." (Gloria Galeano & A. Henderson: Flora Neotropica, Monograph 72)A
