Annual from somewhat succulent roots; stems 10-30 cm, at first erect but often becoming prostrate, the stem sympodial; racemes barely if at all exceeding the leaves; bracts ovate, foliaceous, 3-8 mm; corollas pale yellow, 7-9 mm including the 1-2 mm spur; crest of the upper petal usually toothed; fruits spreading or drooping, 1.5-2 cm, on pedicels often 1-1.5 cm; flowers sometimes cleistogamous; seeds about 2 mm wide, with a narrow, acute ring-margin.

Notes

Flowers April to May

Wetland indicator: FACU

I took these pictures in early June as the plants were beginning to senesce and the flowers that were still being produced appear to be cleistogamous.
