Utricularia gibba L.
Common Name: HUMPED BLADDERWORT
Coefficient of Conservatism: 8
Coefficient of Wetness: -5
Wetness Index: OBL
Physiognomy: Nt P-Forb

Lakes, ponds, pools, marshes, fens, and other wet areas. While masses, sometimes quite large, of foliage of this species may drift in quiet waters, flowering occurs usually on moist, often recently exposed shores, so that the “terrestrial” habit mimics that of U. cornuta, U. resupinata, and U. subulata.

Utricularia gibba apparently does not produce turions, while the stems of U. minor often bear small compact ones up to 2 or even 4 mm broad.
