Ecology & Life History

Basic Description: Small aquatic plant with delicate, branching, submerged stems bearing a few tiny inflated bladders, and flowering stems borne above the water, with 1-3 yellow 2-lipped flowers.
Technical Description: Utricularia gibba (as distinct from U. biflora): Plant with delicate, creeping stems, seldom over 10 cm, forming mats near the bottom in shallow water or on mud. Leaves scattered, alternate, usually forked once, rarely over 5 mm, with a few bladders. Scapes 5-9 (-10) cm tall, 1-3-flowered; bracts 0.5-1 mm long; pedicels spreading-ascending, 5-10 mm long. Calyx lobes 1.8-2.5 mm long. Corolla yellow, 6-12 mm long, with prominent palate; spur thick, obtuse, 3.5-4.5 mm long, equal or shorter than (about half as long as) lower lip. Capsules ca. 3 mm in diameter; seeds flat, winged, angled, 0.6-0.8 mm long (Radford et al. 1968, Gleason and Cronquist 1991). "U. biflora" differs as follows: leaves usually twice-forked; scapes 2-15 cm tall, 1-4-flowered, bracts to 1.5 mm long; pedicels ascending, 5-20 mm long; calyx lobes 2-3 mm long; corolla 8-15 mm long, spur 5-9 mm long, equaling or exceeding lower lip; capsules 2.5-3 mm in diameter, seeds brown, flat, angled, 0.6-0.8 mm long (Radford et al. 1968).
Diagnostic Characteristics: Leaves alternate, all bearing bladders, without inflated petioles, branching mostly once (U. gibba sensu stricto, excluding U. biflora) or twice (sensu lato, including U. biflora), the ultimate segments terete and filiform. Corolla yellow, lower lip little if any longer than the upper. Flowers 1-3 (excluding U. biflora) or 1-4 (including U. biflora) per scape. Plant aquatic. See Radford et al. (1968), Gleason and Cronquist (1991), Great Plains Flora Association (1986).
Duration: ANNUAL
Reproduction Comments: Reproduction is sexual, from perfect flowers. The flowers display specialization for insect pollination (Proctor and Yeo 1973). The seeds are probably water-dispersed.
Lacustrine Habitat(s): Shallow water
Palustrine Habitat(s): Bog/fen, FORESTED WETLAND
Habitat Comments: Utricularia gibba and U. biflora: Shallow water: pools, ponds, ditches, canals, springheads (Fernald 1950, Gleason and Cronquist 1991, Godfrey and Wooten 1981, Great Plains Flora Association 1986, Hough 1983, Radford et al. 1968, Steyermark 1963). U. biflora also reported from swamps (Godfrey and Wooten 1981) and U. gibba from bogs (Fernald 1950, Hough 1983) and sloughs (Steyermark 1963). In Missouri, Steyermark (1963) writes of U. gibba, "often found floating in masses on mucky debris and organic detritus on the surface of upland sink-hole ponds in the Ozarks". In Puerto Rico, U. gibba is found "creeping on the bottom in shallow water at low elevations" (Liogier and Martorell 1982). In California (where it may be exotic) U. gibba is uncommon, occurring in shallow water and mud, below 1600 meters (Hickman 1993).
