Description Terrestrial, acaulescent herbs, rarely with a short caudex; petioles equitant, usually long and slender, mostly geniculate near the apex and terete above the node, commonly vaginate to or above the middle; blades mostly oblong to ovate or lanceolate and cuspidate-acuminate, drying rather thin, the costa stout, the primary and secondary lateral nerves subparallel, approximate, ascending chiefly at a narrow angle, not united into a collective nerve; peduncles equaling or longer than the leaves, the spathe cuspidate, decurrent upon the peduncle, membranaceous, convolute in bud, explanate in anthesis, white or whitish; spadix sessile or stipitate, cylindric, erect, shorter than the spathe, densely many-flowered, flowering from the base upward; flowers perfect, perigoniate, typically 3-parted, sometimes 2- to 4-parted; sepals fornicate at the apex and subtruncate, coherent or united to form a truncate cup; stamens as many as the sepals and opposite them, the short fila- ments dilated and thickened at the apex, gibbous posteriorly, abruptly narrowed at the apex into the connective; anthers ovoid, the cells oblong, exceeding the connective, the cells subopposite, dehiscent by a longitudinal slit that scarcely extends to the base; ovary oblong, commonly 3-celled, the cells 2- to 8-ovulate, the ovules anatropous, attached by short funicles; style continuous with the ovary, conically elongate, and projecting beyond the perianth, or almost none; stigma 3- or 4-lobate, sessile; fruit baccate, rounded or conic at the apex, 3-celled, the cells 1- to 8-seeded; seeds oblong, slightly curved, somewhat reniform, pale yellowish, the testa sparsely striate-verrucose; endosperm abundant.
Distribution Engler and Krause recognize 27 species, widely distributed in tropical America, with one species in the Philippines and the central Malayan region. Seven species are known from Central America.
