Herbs, annual or perennial, terrestrial or occasionally epiphytic, growing in moist, often shaded places. Leaves simple, spirally arranged, alternate or opposite or in verticils, or all radical, exstipulate or with stipular glands at base of petiole.

Lip large, petaloid, often spurred. Petals 3 or 5. Anterior standard erect. Lateral ones (wings) entire or 2 - 3-lobed, sometimes with a short or long and slender dorsal auricle. Stamens 5; filaments short and broad; anthers cohering. Ovary oblong, 5-celled; ovules many, 1-seriate in each cell; stigma sessile, 5-toothed. Capsules short or long, loculicidally dehiscent; valves 5, elastically springing away from a placentiferous axis; seeds smooth or tubercled, glabrous or hairy; albumen absent.
Scattered throughout wet tropical and subtropical regions (especially montane forests) of Asia and Africa, a few species in temperate regions of Asia, Europe and N. America; about 900 species, ca 240 in India.
