"description"><p>Moderate, solitary, unarmed, pleonanthic, monoecious palm. Stem erect, usually enlarged and with a mass of adventitious roots at the base, columnar above, green to brown, longitudinally striate, ringed with close leaf scars. Leaves pinnate, spreading; sheaths tubular, forming a prominent crownshaft and with a prominent chartaceous ligule; petiole short, adaxially channelled with a central ridge, abaxially rounded; rachis elongate, flattened adaxially, rounded abaxially, tomentose; leaflets regularly arranged, acute, single-fold, midrib evident abaxially, marginal nerves thickened, usually
2(–
3) secondary ribs, and numerous tertiary veins on each side, glabrous adaxially, ramenta present abaxially near the base of the midrib, transverse veinlets not evident. Inflorescences infrafoliar, densely and minutely stellate-tometose, branched to
2 orders basally, to
1 order distally; peduncle short, stout; prophyll tubular, terete,
2-keeled laterally, briefly beaked, much shorter than the peduncular bracts; first peduncular bract, complete, tubular, thick, woody, terete, beaked, enclosing a second almost complete and similar peduncular bract, both splitting abaxially and caducous at anthesis, a prominent but much shorter third and sometimes fourth, chartaceous incomplete peduncular bract also developed; rachis about as long as the peduncle, tapering, densely tomentose, angled, bearing spirally inserted, rather large, acute bracts subtending basal branches and smaller rounded bracts subtending distal branches; rachillae elongate, rather stout, stiff, bearing spirally arranged, low, rounded bracts subtending flowers borne in triads of

6, filaments distinct, awl-shaped, inflexed at the apex in bud, anthers oblong in outline, latrorse; pistillode as long as the stamens, cylindrical, with obliquely subcapitate apex. Pollen ellipsoidal asymmetric; aperture a distal sulcus; ectexine tectate, perforate, aperture margin similar; infratectum columellate; longest axis

3, tooth-like, on one side of the gynoecium; gynoecium ovoid, unilocular, uniovulate, stigmas
3, recurved at anthesis, ovule pendulous, anatropous. Fruit ovoid-ellipsoidal with eccentrically apical stigmatic remains; epicarp smooth but drying longitudinally lines, mesocarp with numerous flat longitudinal fibres in thin flesh and some red-brown stone cells near the apex, endocarp thin, fragile, operculate at the base of the elongate hilar seam, not adherent to the seed. Seed ellipsoidal, hilum elongate, raphe branches anastomosing, endosperm homogeneous; embryo basal. Germination adjacent-ligular; eophyll bifid. Cytology not studied.
