Associates

 Distribution

Circumboreal, south in North America to DE, IN, and CA.

Morphology

Herbaceous perennial from turions produced late in the season; stems free-floating or creeping on the soil under shallow water; leaves numberous, mostly 0.5-2 cm, often 3-parted at the base and then 1-3 times dichotomously branched, the segments slender, flat, not much narrower in successive branches, the ultimate segments rather blunt; bladders on specialized branches distinct from the leaves; flowers mostly 2-4 in a lax raceme on an emergent peduncle 6-20 cm; pedicels to 15 mm, remaining erect; corolla yellow, the lower lip 8-12 mm, with well developed palate nearly twice as long as the upper lip; spur nearly as long as the lower lip.

Notes

Flowers Summer

Wetland indicator: OBL

I sometimes find this species occurring in pools as large vegetative mats on wet peat in northern white cedar swamps, otherwise it is usually found in shallow water. I have never found it in flower but it is easy to identify vegetatively because it produces leaves and bladders on separate branches.
