Morphological characters and geographic distribution are the same as those for the family.
Herbs, rhizomatous, 1--2[--5] m, forming small to large monotypic stands. Leaves green [bronze or magenta in hybrids and cultivars], often glaucous [lanuginose]; blade narrowly ovate to narrowly elliptic, 20--70 cm ´ 15--30 cm, base gradually or abruptly tapered, apex acute to acuminate. Inflorescences: peduncles green [magenta], often glaucous; bracts green [magenta], often glaucous; primary bracts to 30 cm, secondary bracts to 20 cm; floral bracts 0.5--3 ´ 0.3--1.5 cm, papery. Flowers nearly sessile, subtended by pedicel bract; sepals usually green [magenta], often less than half size of petals; petals sharply reflexed or not, green or brightly colored, 4--15 cm, generally shorter than staminodes; staminodes pale yellow to deep crimson red; labellum 3--9 ´ 4--10 cm; ovary green [magenta]. Capsules brown, 1.5--6 ´ 2--4.5 cm, warty, becoming papery. Seeds 5--25[--75] per capsule, medium to dark brown or black, 4--10 ´ 4--8 mm.

Mediocre to fairly massive, leafy, rhizomatous herbs; leaves spiral, relatively large, with an eligulate sheath; inflorescence racemiform or paniculate, bracteate, the bracts usually subtending a cicinnus of 2 more or less showy, usually brightly colored perfect flowers; sepals 3, free, more or less foliaceous or petalaceous, es- sentially equal; petals 3, nearly equal, more or less connate at the base; fertile stamen 1, petaloid, bearing a solitary marginal anther, more or less connate at the base with the somewhat petaloid style, a petaloid anterior (labellum) and 2-3 showy posterior staminodia; ovary inferior, 3-celled, conspicuously warty or spiny-fimbriate, containing numerous ovules; fruit a rather large warty or spiny- fimbriate capsule finally opening by the collapse of the pericarp; seeds round and very hard.
