 Distribution

Nova Scotia and northern NY to northern MI, northern MN, and southwest Ontario, south to Long Island, DE and IN; also in GA and FL.

Morphology

Herbaceous perennial; stems delicate, horizontal just below the surface of the soil or on the surface in shallow water, producing linear leaves to 3 cm and from the base of each 1-2 delicate roots with or without bladders; flowering branches erect, 2-10 cm, each with 1(2) flowers; bract tubular, surrounding the stem, its margin notched; flowers violet, 1 cm, tipped backward on the pedicel and facing upward, the spur almost horizontal; lower lip 3-lobed, the palate scarcely developed.

Notes

Flowers July to August

Wetland indicator: OBL

Unique among our bladderworts in that it produced linear leaves evenly spaced along a trailing stem. The flowers are unique and quite beautiful as well, albeit small. Apparently scapes with two flowers are rare, however the last image shows that it can occur.
