Herbs, terrestrial, cespitose, erect. Roots branched. Rhizomes short, rigid. Stems erect, branched or simple, reedlike, slender, hard. Leaves few, cauline; sheaths not articulate; blade convolute, plicate, thin. Inflorescences terminal or occasionally from axils of distal leaves, few-to many-flowered panicles [racemes, rarely glomerate], pedunculate [sessile]. Flowers resupinate, small; sepals subequal; lateral sepals distinct [connate at base], forming small mentum; petals similar to sepals, slightly falcate, shorter than sepals; lip sessile, base saccate; column short, fleshy, with short foot; anther abaxial, erect, subequal to rostellum, more than 1/2 length of column; pollinia 2, sectile; stigma entire; viscidium terminal. Fruits capsules, oblong, cylindric.
Evergreen terrestrial orchids forming small clumps of thin, wiry, sparsely branched, leafy stems.

Flowers non-resupinate, crowded, widely opening. Tepals short broad. Lateral sepals fused at base. Petals fused to base of sepals. Labellum attached to anterior base of column. Labellum lamina unlobed, with prominent basal pouch or spur. Column short, without basal foot.
