Description
Palms 2.3 (1.5-3.5) m tall; stems 2.4 m tall, 1.4 (1.2-1.7) cm in diameter, clustered, cane-like; internodes 1.7 (1.0-2.8) cm long, yellowish and smooth. Leaves 9 per stem, regularly pinnate and the pinnae with 1 mainvein only, not plicate, bases of blades running diagonally into the rachis; sheaths 17.1 (11.5-22.0) cm long; petioles 35.5 (12.0-59.0) cm long, drying green or yellowish; rachis 67.0 (38.0-78.5) cm long, 4.2 (2.6-5.3) mm in diameter veins raised and rectangular in cross-section adaxially; pinnae 33(26-49) per side of rachis; basal pinna 25.4(14.0-38.0) cm long, 0.5 (0.3-0.5) cm wide, forming an angle of 68 (47-89)° cm with the rachis; apical pinna 13.7 (10.0-16.7) cm long, 1.2(0.5-2.8) cm wide, forming an angle of 26( 15-40)° with the rachis. Inflorescences branched 3-4 orders; prophylls and peduncular bracts not ribbed with elongate, unbranched fibers, flattened, deciduous or persistent; prophylls 12.8 (8.1-20.9) cm long, short, asymmetrically apiculate, the margins curved around the stem, the surfaces flat with dense, felty, brown tomentum, prophyll equal to and early deciduous with the peduncular bract, the surfaces not ridged, without unequally wide ridges; peduncular bracts 12.2 (8.0-19.0) cm long, well-developed, inserted 0.4 (0.3-0.7) cm above the prophyll; peduncles 11.5 (7.5-16.0) cm long, 6.0 (4.2-8.5) mm in diameter; rachillae 108 (78-136), 13.2 (11.0-15.0) cm long, 0.8 (0.3-1.0) mm in diameter, the surfaces without spiky, fibrous projections or ridges, drying brown, with faint to pronounced, short, transverse ridges, filiform with extended narrowed sections between the flower pits; flower pits alternately arranged (sometimes distorted by twisting and contracting of 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, joined to form a raised cupule,
