Leaves 9(6-10) per stem, irregularly pinnate, not plicate, bases of blades running diagonally into the rachis; sheaths 14.9(6.0-26.0) cm long; petioles 28.4(5.5-58.0) cm long, drying green or yellowish; rachis 52.5(16.5-101.0) cm long, 4.1(1.4-8.0) mm in diameter; veins raised and rectangular in cross-section adaxially or not raised or slightly raised and triangular in crosssection adaxially; pinnae 6(2-13) per side of rachis; basal pinna 23.8(8.5-50.0) cm long, 4.1(0.7-34.5) cm wide, forming an angle of 64(31-92)° with the rachis; apical pinna 16.6(6.7-31.5) cm long, 12.7(5.5-30.0) cm wide, forming an angle of 38(27-50)° with the rachis. Inflorescences branched 1-2 orders; prophylls and peduncular bracts not ribbed with elongate, unbranched fibers, flattened, deciduous; prophylls 9.0(3.3-16.0) 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 7.5(4.0-11.6) cm long, well-developed, inserted 0.3(0.1-0.6) cm above the prophyll; peduncles 8.8(3.8?16.0) cm long, 4.9(2.3-9.2) mm in diameter; rachillae 6(2-18), 23.3(10.0-42.0) cm long, 3.2(1.9-5.3) mm in diameter, the surfaces without spiky, fibrous projections or ridges, drying brown, with 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 deciduous after anthesis; stamens 6; thecae diverging at anthesis, inserted onto bifid and well-developed, nonjointed connectives; 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 6.5(5.1-7.9) mm long, 5.3(4.3-6.3) mm in diameter, the bases without a prominent stipe, the apices not conical, the surfaces not splitting at maturity, without fibersemerging, bumpy from the numerous, subepidermal, tangential, short fibers present, these coming to a point at fruit apices; locular epidermis without operculum, smooth, without pores.
