They have ribbed ovoid psuedobulbs with 2 to 3 apical thin, heavily veined leaves. The inflorescence arises from the base of the psuedobulb and hangs with many non resupinate, upside down flowers on a pendant spike. This orchid has brightly coloured flowers that produce a powerful fragrance attractive to bees. These plants are epiphytes and many are found in association with ant nests.
