Description

Palm 1.4 (0.3-2.5) m tall; stems 0.7 (0.1-3.0) m tall, 1.5 (0.4-3.4) cm in diameter, solitary or clustered, not cane-like or cane-like; internodes 0.9 (0.2-2.2) cm long, yellowish and smooth, or, if short and congested, not scaly. Leaves 10 (4-17) per stem, undivided or irregularly pinnate, not plicate, bases of blades running diagonally into the rachis; sheaths 20.0 (9.0-51.0) cm long; petioles 30.7 (0.2-113.5) cm long, drying orangebrown, reddish-brown, or green or yellowish; rachis 46.4 (12.0-250.0) cm long, 4.1 (1.3-9.0) mm in diameter; veins raised and rectangular in cross-section adaxially or not raised or slightly raised and triangular in crosssection adaxially; pinnae 3 (1-35) per side of rachis; basal pinna 32.7 (12.5-68.0) cm long, 5.8 (0.3-21.5) cm wide, forming an angle of 31(3?95)° with the rachis; apical pinna 22.9(8.5-44.0) cm long, 10.7(1.5?37.0) cm wide, forming an angle of 31 (10-50)° with the rachis. Inflorescences unbranched; prophylls and peduncular bracts ribbed with elongate, unbranched fibers, both bracts tubular, narrow, elongate, closely sheathing the peduncle, more or less persistent; prophylls 16.5 (4.0-38.0) cm long, not short and asymmetrically apiculate, the surfaces not ridged, without unequally wide ridges; peduncular bracts 32.6 (16.5-67.0) cm long, well-developed, inserted 1.4 (0.4-5.7) cm above the prophyll; peduncles 51.3 (13.7-117.0) cm long, 3.0 (1.1-8.2) mm in diameter; rachillae 1, 20.4(5.5-52.0) cm long, 5.4(1.9-10.5) mm in diameter, the surfaces without 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 pits with a central notch before anthesis, often the two sides of the notch overlapping, 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 almost directly onto the filament apices, the connectives bifid but scarcely developed; anthers short and curled over at anthesis; non-fertilized pistillate flowers persistent or deciduous after anthesis; staminodial tubes crenulate or shallowly lobed at the apex, those of non-fertilized flowers not projecting and persistent after anthesis; fruits 7.6 (5.0?11.6) mm long, 5.4 (4.4-6.5) 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 or sculpted and then usually also with a raised, meridional ridge, without pores.

Culture

It is rather rare in cultivation, and prefers a protected spot in the understory of the warm temperate or tropical garden.

Comments and Curiosities

Uses: The Awá of Ecuador, use it for roof thatching, Medicinal and Veterinary purposes, the Tsáchila of Ecuador, use it for rituals and dye, and the Cayapa of Ecuador use it for food. (Henderson, A.J. 2011)/Palmweb.
