Adenoncos parviflora is an epiphytic orchid with distinctive features. Its leaves are unusually fleshy, and curved, and have grooves on the upper side. These leaves are cylindrical and look similar to round rods.

During the winter season, this orchid produces flowers on very short stems that emerge from the base of its leaves. The flowering stems are often found in groups of up to three from a single node. Each stem can bear one to two fleshy flowers.
