Herbs (2–) 3–6 (–7) dm. Stems branched distally, hairs in­curved. Leaves: petiole 1–2.5 mm; blade mostly lanceolate or narrowly ovate to elliptic, sometimes obovate proximally, 15–60 × 2–10 mm, base cuneate, apex usually acute to attenuate-acuminate, sometimes obtuse proximally. Racemes 2–20 (–30) × 0.3–0.6 cm; peduncle to 6 cm; bracts narrowly lanceolate or ovate-subulate. Pedicels 0.4–0.5 mm, pubescent. Cleistogamous flowers usually present on much-reduced axillary branches, chasmogamous flowers sometimes absent, 1.5–2.1 mm. Flowers: non-wing sepals ovate to lanceolate, 1.2–1.8 mm; wings obovate, 1–2 mm wide; keel 1.5–3 mm. Fruits ovoid, subglobose, or subobovoid, 3–5 × 2.8–4 mm. Seeds 2–3 mm.


Phenology: Flowering (mid–)late summer–fall.
Habitat: Igneous, lime­stone, gravelly, sandy, or silty loam soils, in dry to moist, open to shaded grasslands, shrublands, woodlands, disturbed areas.
Elevation: 1200–2600 m.
