Inflorescences infrafoliar; peduncle 6-9 cm long; prophyll ca. 54 cm long; peduncular bract ca. 60 cm long, prophyll and peduncular bract same color as sheath; rachis 20-30 cm long; rachillae 48-97, 48-60 cm long, 2.5-3.5 mm diam. at anthesis, densely covered with short, stiff, branched, whitish brown, 0.1 mm long hairs; fruits 0.8-1 cm diam.

Discussion:Local names and uses. Brazil: açaizinho, assaí de caatinga, assaí de catinga, assaí chumbinho, assaí cubinha; Colombia: asaí de sabana, asaí paso, guasaí pequeno; Peru: huasaí de varillal; Venezuela: manaca. The stems are used in house construction, the leaves are used for thatching temporary shelters, and mature fruits are occasionally used to make a drink. Spruce (1871) wrote: “It varies so much in the quality of the fruit that, were not all essential 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, and 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."

Distribution and Ecology: Western Amazon region in Colombia (Amazonas, Caquetá, Guainía, Guaviare, Vaupés), Venezuela (Amazonas, Bolívar), Peru (Loreto), and Brazil (Amazonas) (Fig. 13); open or dwarf forest in wet, poorly drained areas on white-sand soil and black-water drainage areas below 350 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.).
