Description:
A short monopodial epiphyte with roots that are 0.1-0.2 in. (0.3-0.4 cm) in diameter. Pseudobulb/stem: The stem is very short and hidden by overlapping leaf bases. Leaves: 2.4-8.0 in. (6-20 cm) long by 0.6-2.8 in. (1.5-7.0 cm) wide. Three to eight broadly egg-shaped to elliptic or oblanceolate leaves are closely spaced and distichously arranged along the stem. They are leathery, dark green, unequally bilobed at the apex, and have undulate margins. Inflorescence: 1.2-3.5 in. (3-9 cm) long. The flower spike is pendent. Flowers: 2-6 blossoms are usually produced, but occasionally a plant may have as many as 12. The fragrant blossoms have white sepals and petals, and the lip is white with a green and a purple-brown blotch The narrowly oblong-elliptic sepals are sharply pointed and measure 0.8-1.0 in. (2.0-2.5 cm) long by 0.2-0.3 in. (0.6-0.7 cm) wide, with the lateral sepals being slightly longer than the dorsal sepal. Petals are slightly shorter and broader than the sepals. The lip is 0.8-1.1 in. (2.0-2.7 cm) long by 0.8-1.0 in. (2.0-2.5 cm) wide. It is very concave, the margin is undulate irregularly notched or scalloped, and it tapers to a conical spur at the base that is 0.8-1.0 in. (2.0-2.5 cm) long, is constricted in the middle, and then swells again at the tip which bends downward.
