Moderate, mostly solitary, rarely clustered, armed or unarmed, pleonanthic, hermaphroditic palms. Stem clothed with persistent leaf sheaths, in age becoming bare. Leaves induplicate, shortly costapalmate, marcescent; sheath becoming fibrous, persistent, eventually splitting basally; petiole short or long, concave, flattened, or channelled adaxially, rounded abaxially, margins unarmed or armed with sparse to dense, small or large teeth, sometimes floccose; adaxial hastula triangular to irregular, thin, membranous, at length fibrous, sometimes large, abaxial hastula a very low ridge or scarcely developed; blade nearly orbicular, regularly divided nearly to the middle or beyond into single-fold, stiff or flexible segments, deeply bifid at the apex, interfold filaments often present, surfaces glabrous, waxy or covered in caducous, floccose indumentum, midribs prominent, other veins fine, ± equal and close together giving a striate appearance, transverse veinlets inconspicuous, sometimes evident abaxially. Inflorescences solitary, interfoliar, nearly equalling or exceeding the leaves, erect or curving, branched to 4 orders; peduncle slender, short to medium; prophyll 2-keeled, closely sheathing, tubular, glabrous (?always), splitting irregularly abaxially; peduncular bracts 0–several, like the prophyll but single-keeled, glabrous or floccose; rachis much longer than peduncle; first-order branches distant, apparently lacking prophylls; subsequent bracts triangular, membranous, very inconspicuous; rachillae crowded, numerous, all branches and rachillae covered in a pale dense felt or deep pile of hairs. Flowers spirally arranged, solitary or in cincinni of 2–3, each subtended by a small bract, buds sometimes obscured by hairs until anthesis; sepals 3, distinct, imbricate, margins minutely toothed (?always); petals 3, united basally in a tube as long as the sepals, briefly imbricate, valvate apically, shallowly to deeply furrowed adaxially; stamens 6, borne at the mouth of the corolla tube, filaments connate into a 6-lobed ring, lobes triangular, abruptly narrowed at tips, anthers broadly elliptic to nearly oblong, dorsifixed, ± versatile, latrorse; carpels 3, follicular, united by the styles, ovule basal, erect, anatropous. Pollen ellipsoidal, slightly to extremely asymmetric; aperture a distal sulcus; ectexine tectate, finely perforate, perforate and micro-channelled, or perforate-rugulate, aperture margin slightly finer; infratectum columellate; longest axis 29–51 µm [4/10]. Fruit usually developing from 1 carpel, globose or ovoid, dark blue to black at maturity, abortive carpels basal, stigmatic remains apical; epicarp smooth, mesocarp fleshy, endocarp crustaceous. Seed basally or subbasally attached, globose or ellipsoidal, endosperm homogeneous, very shallowly to deeply penetrated by a smooth intrusion of seed coat; embryo subbasal to lateral. Germination remote-ligular; eophyll entire. Cytology: 2n = 36.
