Leaflets velvety on the lower surface, margins frequently almost parallel, often abruptly rounded at both ends and with a notch at the tip. Flowers small, purple to dark blue with yellow stamens extending beyond the single petal, crowded in narrow, 3-6 in., spikelike clusters at or near the ends of the branchlets, appearing from April to June. Fruit small, up to 3/8 inch long and with blisterlike glands visible under a 10x hand lens. This is a deciduous plant.
