Arboreous unarmed palms with solitary, naked, ringed stems. Leaves 

 terminal, large, the old ones deciduous; the blade flabellate, expanded in outline 

 for a more or less extensive portion of a circle, usually broadly cuneate at the 

 base, undivided in the central part, and more or less deeply multifid on the 

 peripherv; the segments more or less deeply bifid, usually, with interposed fila- 

 ments ; the upper face of the blade is devoid of stomata. Petioles always 

 unarmed, ligulate at apex anticously, and passing behind without interruption 

 into a short rachis. The majority of the mid-costas of the segments start from 

 the apex of the petioles, but some also from the sides of the rachis. Spadices 

 interfoliaceous, composed of one panicle only, more or less, branched, or, at times, 

 of 2-4 distinct similar panicles, each of which is borne on the end of a distinct 

 pedimcular part; spathes several, coriaceous, the lower sheaths the peduncular 

 part, and the upper ones (2 or more in number) are concave, lanceolate, boat- 

 shaped, or ass's-ear-like, and embrace the flowering panicle. Flowers her- 

 maphrodite, scattered, or else spirally arranged on the branchlets and solitary 

 (never glomerulate) and sessile on bracteate pulvinuli; special floral bracteolae 

 none. Calyx tubular or cyathiform-companulate, more or less solid in its lower 

 portion; the limb slightly 3-toothed. Corolla considerably longer than the calyx; 

 it has a permanent tube, and three valvate divisions, the latter deciduous at the 

 time of anthesis. Stamens 6; the filaments with their united bases form at the 

 faux of the corolla, a ring, crowned by six filamentose subulate apices; anthers 

 linear, or linear-oblong, or linea-sagittate, dorsifix, at first erect, versatile during 

 anthesis, dehiscing internally. Ovary conical, ovate, obovate, or else turbinate; 

 composed of three half free, uniovulate carpels; the latter deeply sculptured above,
