Trailing terrestrials rooting at the nodes, rarely saprophytes. Leaves spiralled, petiolate, clustered toward the stem apex. Inflorescences terminal pedunculate racemes, the floral bracts conspicuous. Flowers barely opening, pubescent, somewhat secund. Sepals and petals free, the petals appressed to the dorsal sepal. Lip unlobed, sessile, with strongly involute margins forming a narrow tube, bisaccate at the base with callus appendages (vesicles) insides the sacs. Column short with an elongate rostellum; pollinia 2, naked.

From the Greek kystis, meaning bladder, and orchis, meaning orchid, referring to the inflated base of the lip.
