Epiphytic herbs with a short many-leaved stems. Leaves distichous, linear, unequally bilobed at apex. Inflorescence spreading, elongate, laxly few–many-flowered. Flowers small, pedicellate. Sepals and petals free, subsimilar. Lip obscurely 3-lobed, concave at base, ovate, acute, spurred, ecallose; spur filiform, elongate, longer than or equalling lip in length. Column short, fleshy; anther hemisphaerical, erose on apical margin; pollinia 2, ovoid; stipites 2, very short, slender; viscidia 2, oblong-elliptic, twice as long as each stipes; rostellum complex, porrect, 3-pronged in front and behind, the central prong in front shorter than the outer ones.
