Small, epiphytic herbs with or without pseudobulbs. Leaves usually flat, rarely equitant, coriaceous or fleshy. Inflorescences arching or pendulous, few-to many-flowered racemes, or rarely panicles, produced from the bases of the pseudobulbs or axils of the leaves. Flowers usually small, rarely of moderate size, on slender pedicels, the subtending bracts usually narrow. Sepals subequal, usually narrow, erect or spreading, free or with the laterals more or less connate. Petals subequal to the sepals or smaller. Lip entire or obscurely lobed, usually clawed at the base, rarely sessile, continuous with the base of the column, the lamina triangular or hastate, acuminate, the disk smooth or with a carinate callus. Column erect, terete or sulcate, glabrous, papillose or velutinous, without wings or appendages, the apex usually slightly recurved, the rostellum more or less elongate, acuminate, erect, the base of the column without a foot. Anther erect, oblong, imperfectly 2-celled, above the cells more or less long-appendaged and applied to the rostellum; pollinia 2, waxy.
