Pseudobulbless, epiphytic herbs with either distichous, monopodial, leafy stems, or stemless and leafless clusters of thickened roots. Leaves oblong or ligular, coriaceous, sometimes absent. Inflorescences short, usually densely flowered racemes, produced from the axils of the leaves or from the centers of the root clusters. Flowers minute, often more or less distichously arranged on the scape. Sepals subequal, free, connivent, or with the apices spreading. Petals subequal to the sepals or sometimes smaller. Lip sessile at the base of the column and produced into an elongate, often recurved spur, the blade entire or 3-lobed, subequal to the sepals in length, often with the lateral margins more or less convolute at the base. Column very short, wingless, the base without a foot. Anther terminal, operculate, incumbent, 2-celled; pollinia 2, waxy.
