Epiphytic herbs, with more or less flexuose, monopodial, foliaceous stems, up to about 35 cm. long, enveloped in the conduplicate bases of the distichous leaves. Roots alternating with the leaves and equidistantly distributed along the stem. Leaves broadly ligular to elliptic-oblong, obtuse to unequally bilobed at the apex, the blades about 4-9 cm. long and 1.2-2 cm. wide, articulated to the persistent, sheathing bases and ultimately deciduous below. Inflorescences short, lateral, densely flowered racemes 3-4 cm. long, produced from the sides of the stems just below the point of emergence of the roots. Flowers very small, white or yellowish white, distichously arranged on the scape. Sepals of about equal length, linear-ligular, shortly acuminate, slightly concave, the margins of the lower portions connivent, with the apices spreading, 4-4.5 mm. long and about 0.75 mm. wide; lateral sepals usually rather oblique. Petals narrowly ligular, rather concave, acute, subequal to the dorsal sepal in length, about 4 mm. long and 0.75-1 mm. wide. Lip 3-lobed, about equaling the lateral sepals in length, the sessile base affixed to the base of the column and produced into an elongate, obtuse, incurving spur, about 4 mm. long, the short, lateral lobes of the blade acute or semiovate, erect in natural position, about 1.5 mm. wide when spread out, the mid-lobe narrowly triangular or linear-ligular, rather acute, about 2.5 mm. long and 0.75 mm. wide.
