Perennial, freely suspended aquatic herbs; stolons filiform, terete, to 30 cm long or longer, 0.5-1.5 mm thick. Photosynthetic organs conspicuous, alternate on the stolons, 1.5-3.0 cm long, repeatedly dichotomously divided into capillary seg-ments, the ultimate segments sparsely setulose. Traps lateral on the segments, oblique, broadly ovoid, 1-2 mm long, short stalked, the mouth lateral, naked or with 2 short simple setiform appendages. Inflorescences erect, emergent, 3-10 cm long, the 3-6 flowers widely spaced on the axis, the lowermost flower cleistoga-mous, at or very near the base of the peduncle; bracts basifixed, broadly ovate-deltoid, auriculate, 2-3 mm long, the sterile scales absent; pedicels at first erect becoming sharply reflexed in fruit. Flowers with the calyx lobes subequal, broadly ovate, the apex of the upper lobe obtuse, that of the lower lobe deeply emarginate; corolla red or pink, ca. 8 mm long, the upper lip orbicular, the apex entire, 4-5 mm wide, the lower lip transversely oblong, the apex emarginate, 6-8 mm wide, the palate slightly gibbous, the spur conical-subulate, obtuse, shorter than the lower lip. Capsules globose, ca. 3 mm in diam. with a persistent style 1-1.5 mm long, circumscissile; seeds depressed globose, ca. 0.5 mm in diam., finely reticulate.
