''Cleistesiopsis'' is a terrestrial orchid with an underground network of spreading fibrous roots. It is found in small clusters of single flowering stems, each with a single leaf blade about halfway up the 30 – 45 cm stem. A smaller floral bract clasps around the base of the flower and appears as a second smaller leaf blade. The flower has three brown-green sepals spreading upward from the stem. Two upper petals and a lip below form the flower tube.
''Cleistesiopsis'' flowers in the spring (April to May) along coastal plain area and around July in the mountains. It prefers savannas, meadows, openings woodlands, where the soil is acidic and moist and made up of rotting pine or other organic material, such as a boggy pine woodland. In the mountains that habitat may be xeric.[Gregg, K. B. 1989. Reproductive biology of the orchid ''Cleistes divaricata'' (L.) Ames var. ''bifaria'' Fernald growing in a West Virginia meadow. Castanea 54: 57–78.]
The plants are commonly up to 30 to 45 centimeters in height. The flowers are 2–3 cm across, depending on species.
