Kartesz, J.T. 1999. A synonymized checklist and atlas with biological attributes for the vascular flora of the United States, Canada, and Greenland. First edition. In: Kartesz, J.T., and C.A. Meacham. Synthesis of the North American Flora, Version 1.0. North Carolina Botanical Garden, Chapel Hill, N.C.
Taxonomic Comments
This record represents the broad concept of Utricularia gibba, including U. biflora, and U. fibrosa Walt. following Kartesz (1999). Kartesz's 1999 Synthesis includes U. fibrosa Walt. in U. gibba, while U. fibrosa Britt. is placed in U. striata. In contrast, Kartesz's 1994 checklist accepted U. fibrosa Walt. and U. gibba (including U. biflora) as distinct. Also differing, the treatment in Weakley (2010 draft) includes U. fibrosa Walt. in U. striata and accepts U. biflora and U. gibba as distinct.

Range Extent>2,500,000 square km (greater than 1,000,000 square miles)
Number of Occurrences81 to >300
Rank Reasons
Widespread from tropical America, including the Caribbean, to southeastern Canada; also in the Old World. Common in parts of its range.
Range Extent Comments
Nova Scotia to Ontario and Minnesota, south to Florida, west to Iowa, Missouri, Kansas, Oklahoma and Texas; in the west, from British Columbia south to California (where it was probably introduced - Hickman 1993). Also in Mexico, Central and South America and the West Indies, including Jamaica, Puerto Rico, and the Bahamas. Also in the Old World (Africa, Asia).
Ecology & Habitat

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).

Habitat

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).

Reproduction

Reproduction is sexual, from perfect flowers. The flowers display specialization for insect pollination (Proctor and Yeo 1973). The seeds are probably water-dispersed.
