Epiphytes or terrestrial plants. Roots thin. Stem elliptic in cross section; internodes several, enlarged, each enclosed by a semi-transparent scaled leaf with distinct venation; leaves on upper half of stem or with few leaves near the apex. Leaves linear, lanceolate or narrowly elliptic, usually coriaceous and with out a distinct petiole. lnflorescence often from a pit in the stem, lateral, erect or nodding, usually with scale-­like, brown hairs; floral bracts conspicuous. Flower colour variable . Sepals outside densely to laxly pubescent. Median sepal narrowly triangular to narrowly elliptical. Lateral sepals triangular, ventrally broadened at the base; mentum distinct. Petals similar in size and colour to dorsal sepal. Lip 3-lobed, hinged at the base, usually with papillose keels.
