According to J J Vermuelen this section is defined by creeping rhizomes with distinct to minute pseudobulbs carrying 2, apical, decidous leaves that blooms on a subumbellate to elongate, racemose, 2 to many flowered inflorescence carrying resupinate flowers with the pedicel basal node more or less level with the attachment of the floral bract. The free dorsal sepals are 1 to 5 veined, have entire, to erose, to irregularily fimbriate, to paleate margins, the laterals are free to adnate usually along the lower margin, are 3 to 5 veined and are 1 to 6.9 times as long as the dorsal. The petals are usually single veined with entire to fimbriate to paleate magins. The undivided mobile lip is on a thin ligament and the stigma of the column is not proximally protruding. The anterior surface of the anther is not concave and the anterior margin is drawn out to a beak or not. There are 4 pollina.

There are about 32 species in forests at elevations up to 400 meters in India, Nepal, Bhutan, China, Myanmar, Laos, Vietnam, Thailand, penninsular Malaysia, Sumatra, Java and Borneo.
