Description

Palm 1.8 (0.4-4.0) m tall; stems 1.4 (0.2-5.0) m tall, 0.7 (0.3-1.6) cm in diameter, solitary or clustering, not cane-like; internodes 3.0 (0.4-8.4) cm long, yellowish and smooth. Leaves 8 (4-17) per stem, undivided or irregularly pinnate, not plicate, bases of blades running diagonally into the rachis; sheaths 8.9 (1.0-22.0) cm long; petioles 12.9 (1.0-58.0) cm long, drying green or yellowish; rachis 29.6 (10.1-75.8) cm long, 2.6 (0.9-6.0) mm in diameter; veins raised and rectangular in cross-section adaxially or not raised or slightly raised and triangular in cross-section adaxially; pinnae 2 (1-12) per side of rachis; basal pinna 20.4 (8.0-38.0) cm long, 3.4 (0.6-11.4) cm wide, forming an angle of 40 (9-112)° with the rachis; apical pinna 2.6 (3.2-38.5) cm long, 10.3 (1.5-23.5) cm wide, forming an angle of 34 (14-50)° with the rachis. Inflorescences unbranched or branched 1 order; prophylls and peduncular bracts not ribbed with elongate, unbranched fibers, flattened, deciduous or persistent; prophylls 6.8 (0.7-21.3) cm long, not short and asymmetrically apiculate, the surfaces not ridged, without unequally wide ridges; peduncular bracts 0.6 (0.1?9.6) cm long, vestigial, the prophyll three times or more long, sometimes the peduncular bract apparently well-developed but then soon disintegrating, inserted 1.8 (0.1 ? 9.5) cm above the prophyll; peduncles 5.0 (0.5-17.0) cm long, 3.2 (1.3-6.1) mm in diameter; rachillae 1 (1-7), 12.7 (1.5-37.0) cm long, 5.4 (1.2-15.1) mm in diameter, the surfaces with spiky, fibrous projections or ridges, drying brown or yellow-brown, without short, transverse ridges, not filiform and not narrowed between the flower pits; flower pits spirally arranged, glabrous internally; proximal lips without a central notch before anthesis, not recurved after anthesis, not hood-shaped; proximal and distal lips drying the same color as the rachillae, not joined to form a raised cupule, the proximal lip margins overlapping the distal lip margins; distal lips well-developed; staminate and pistillate petals not emergent, not valvate throughout; staminate flowers persistent or deciduous after anthesis; stamens 6; thecae diverging at anthesis, inserted onto bifid and well-developed, non-jointed connectives; anthers short and curled over at anthesis; non-fertilized pistillate flowers persistent after anthesis; staminodial tubes crenulate or shallowly lobed at the apex, those of non-fertilized pistillate flowers not projecting and persistent after anthesis; fruits 8.6 (5.9-14.5) mm long, 5.6 (4.0-7.3) mm in diameter, the bases without a prominent stipe, the apices not conical, the surfaces not splitting at maturity, without fibers emerging, ridged from the numerous, subepidermal, meridional, elongate fibers present, these coming to a point at fruit apices; locular epidermis without operculum, smooth, without pores.

Culture

Comments and Curiosities

Uses: Leaves are used for thatch, to tap baskets, and for wrapping. Stems are used for walking sticks. The palms heart is chewed to protect teeth from rotting. Seeds are used in blowguns to shoot small birds. (Henderson, A.J. 2011)/Palmweb.
