Herbs, with horizontal usually submerged leafy stems. Leaves alternate, 3-parted from the very base, the middle lobe erect and linear, the lateral lobes capillary and root-like, bladder-bearing; bladders slightly beaked, but without bristles. Inflorescence strictly 1-flowered, the pedicel continuous with the scape, its point of origin marked by the solitary bract, appearing like a scale above the middle of the scape; true scales none; bract basally inserted, amplexi-caul and tubular, the free margin truncate, more or less deeply 2-notched, without bractlets. Calyx 2-parted, the lobes concave, herbaceous, appressed to the mature capsule. Corolla very strongly 2-lipped, the palate a mere convexity at the base of the lower lip. Anthers not lobed. Capsule many-seeded. [Latin, a couch, from the transverse position of the corolla.]

Two species, the following, and another, in tropical South America. Type species: Utricularia resupinata B. D. Greene.
