Small sympodial epiphytes or lithophytes. rarely terrestrials. Rhizomes very short, Stems either branching and forming dense mats, or not branched, tufted, elongated, wiry, not fleshy, many-leaved .Leaves duplicate, distichous, dorso-ventrally flattened or laterally compressed, deciduous or not, usually less than 1 cm long, stiffly thin-textured to carnose, glabrous; sheathing at the base. Inflorescence terminal, sometimes lateral as well, usually less than 2 cm long, a few- to several-flowered raceme or carrying a single flower. Flowers usually opening in succession, very small, resupinate, often hardly opening, usually whitish with purple spots at the apex. Lateral sepals connate at the base or free, forming a mentum, sometimes also the dorsal sepal connate with the lateral sepals. Petals free, usually narrower than the dorsal sepal. Lip entire or obscurely 3-lobed, without spur, not mobile, inside with a simple or 2-lobed appendage. Column foot present; anther erect; pollinia 4, solid, enveloped in tubular sheaths; caudicles absent; stipe absent; viscidium present.

2a Pollinia with a single viscidium == section Podochilus (synonym: sect. Apista)
2b Pollinia with two viscidia == section Diadena
