From 8°24-17°04'S and 35°04-41°23'W in the Atlantic Coastal Forest of Brazil from Pernambuco to Bahia, with an inland outlier in Bahia, at 291(20-770) m elevation in lowland rainforest.

Description

The leaf in shade was purple black and had a salmon pink emerging new leaf, in the sun it is was a dark purple green and the leaf had the texture of leather.

Small palm 1.9 (1.0-3.0) m tall; stems 2.3 (1.5-3.0) m tall, 0.7 (0.5-1.2) cm in diameter, solitary or clustered, canelike; internodes 2.0 (0.9-2.9) cm long, yellowish and smooth. Leaves 12 (7-19) per stem, undivided or irregularly pinnate, not plicate, bases of blades running diagonally into the rachis; sheaths 8.4 (3.7-15.5) cm long; petioles 12.8 (4.5-27.0) cm long, drying green or yellowish; rachis 24.2 (13.0-44.0) cm long, 2.5 (1.2-4.5) mm in diameter; veins not raised or slightly raised and triangular in cross-section adaxially; pinnae 2 (1-6) per side of rachis; basal pinna 17.5 (10.5-26.0) cm long, 3.0 (1.4?6.0) cm wide, forming an angle of 36 (14-66)° with the rachis; apical pinna 11.8 (7.0-18.5) cm long, 8.3 (5.0-18.0) cm wide, forming an angle of 30 (17-45)° with the rachis. Inflorescences unbranched or branched 1 order; prophylls and peduncular bracts not ribbed with elongate, unbranched fibers, flattened (if tubular, narrow, and elongate then not ribbed), deciduous or persistent; prophylls 13.5 (7.0-19.0) cm long, not short and asymmetrically apiculate, the surfaces not ridged, without unequally wide ridges; peduncular bracts 12.4 (5.4-18.5) cm long, well-developed, inserted 3.1 (1.6-5.1) cm above the prophyll; peduncles 20.8 (10.5-33.5) cm long, 2.7 (1.2-5.0) mm in diameter; rachillae 3 (1-6), 10.7 (4.7-18.2) cm long, 2.9 (1.6-4.3) 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 usually spirally arranged, sometimes decussately or tricussately, then the groups not closely spaced nor consistently arranged throughout the rachillae, 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 lipmargins overlapping the distal lip margins; distal lips well-developed; staminate and pistillate petals not emergent, not valvate throughout; staminate flowers 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 deciduous after anthesis; staminodial tubes crenulate or shallowly lobed at the apex, those of non-fertilized pistillate flowers not projecting and persistent after anthesis; fruits 9.6 (7.3-12.1) mm long, 7.4 (5.6-8.5) mm in diameter, the bases with a prominent, asymmetric stipe, the apices conical with rounded apices, the surfaces not splitting at maturity, without fibers emerging, not bumpy, not apiculate; locular epidermis without operculum, sculpted, usually also with a raised, meridional ridge; locular epidermis without pores.
