Stems rather stout, simple or usually somewhat branched above with ascending branches, smooth, 1 to 3 feet high. Leaves sessile, opposite or some of them alternate, narrowly lanceolate, 2 to 5 inches long, the lower ones deeply lobed, the lobes oblong, blunt, short and crenately toothed, with a thickened margin. Flowers pale yellow, three-fourths to 1 inch long, in short clusters or spikes at the ends of the stems and branches, the flowers subtended by the upper reduced leaves. Calyx two-lobed, the lobes with toothed leaflike margins. Corolla with a slender tube and deeply two-lipped, the upper lip (galea) laterally compressed, arched and terminated by a short, blunt beak, the lower lip three-lobed, erect-ascending, the middle lobe smallest. Stamens four, attached to the inside of the corolla tube and ascending within the upper lip but not projecting out of the flower. Fruit a small, ovate capsule as long as or but slightly longer than the calyx.

In low, wet meadows, swamps and marshes, Ontario to Manitoba and South Dakota, south to Connecticut, North Carolina, Ohio and Nebraska. Flowering from August to September.
