Weakly erect herb, to c. 50 cm high. Largest ultimate segments of leaves to 5 mm long and 2 mm wide, rarely more. Raceme usually much longer than peduncle; peduncle stout. Bracts 1/3–3/4 as long as pedicel. Pedicel rather thick, straight, remaining suberect. Sepals peltately attached, ovate, 2–3.5 mm long, 1–2.5 mm wide, dentate, narrower than corolla. Corolla (7–) 9–13 mm long, pink; inner petals dark purplish at apex with a yellowish central stripe; upper petal concolorous or rarely purplish at apex; lower petal linear or narrowly spathulate, commonly recurved, more than 0.5 mm wide medially. Fruit 2–2.5 mm long and wide, rather straight-sided, keeled toward base, truncate at base, slightly pointed or rounded at apex, rugulose-tuberculate when dry, with prominent apical pits.

Prefers well-drained, acidic soils, rare in alkaline soils. Occurs across a wide range of habitats.
