General: Perennial aquatic herb without roots; stems very slender, floating, submerged or creeping along the bottom, leafy, up to 75 cm long.
Leaves: Alternate, numerous, 0.3-1 cm long, divided into 3 parts at the base and then again 1-3 times into 5 flattened, ultimate segments, narrowed towards the tips, margins glabrous; bladders few, borne on the leaves and 1-2 mm wide; winter buds 2-9 mm long, glabrous.
Flowers: Inflorescence of 3-9 flowers in lax racemes at the end of stalks 4-15 cm long; corollas pale yellow, the tubes short, lower lips narrow, 4-8 mm long, spurs sac-like, poorly developed as a hump below the lower lip; bracts ear-like at the bases.

Notes: The illustration U. minor in Hitchcock et al. (1959) is actually of U. ochroleuca (Ceska and Bell 1973). See the latter paper for flower and leaf illustrations of our Utricularia species.
