Description:Variety Description - Stems solitary. Leaves 10-20; sheath 0.7-1.6 m long; petiole (0-)18-57 cm long; rachis 2.1-3.6 m long; pinnae (43-)48-91 per side, with a prominent midvein; basal pinna 60-70 x 0.2-0.5 cm; middle pinnae 62-88 x 1-2 cm; apical pinna 36-44 x 0.5 cm. Inflorescences infrafoliar; peduncle 10-15 cm long; prophyll 70-85 cm long; peduncular bract 55-70 cm; rachis 30-94 cm long; rachillae 70-200, basal rachillae 55-80 cm long, apical ones to 35 cm long, 4-5 mm diam. at anthesis, 5-6 mm diam. in fruit, densely covered with 0.1-0.5 mm long, whitish, much branched, flexuous hairs; staminate sepals densely pilose abaxially, drying white; pistillate sepals densely pilose abaxially, drying white; fruits globose, 1-1.3 cm diam.

Discussion:The type of Euterpe confertiflora is sterile, but the leaves seem to belong to E. precatoria. Bailey, however, described the fruits (which we have not located) as having ruminate endosperm. The types of Euterpe langloisii and Euterpe petiolata (both formerly at B) have not been located, and are presumed destroyed. These names are interpreted from Burret’s descriptions, and from more-recent collections from the type localities. There is little doubt as to their status as synonyms.

Though it is a useful palm throughout its range, Euterpe precatoria var. precatoria is not used as much as either E. edulis or E. oleracea. The fruits are collected and used to make a drink. The stems are commonly used in house construction. The roots are used medicinally for muscle aches and snake bites, and a decoction from the roots is taken (Tukana, Colombia) for malaria (Glenboski C-131). A decoction from the leaves is used to alleviate chest pains (Chácobo, Bolivia). The leaves are used to make brooms and as a source of temporary thatching. In Amazonian Venezuela, the peduncular bract is used to roll cigar tobacco (Zent, label data).
