Stems (8–)20–60(–80) cm long; stems and leaves pubescent with rough, unbranched, spreading hairs 1.0–2.5 mm long in addition to the shorter, forked and stellate hairs. Stem leaves (0.8–)1.5–5.5(–7.0) cm long, margins entire or minutely toothed, the base arrowhead-shaped or minutely auriculate. Sepals 2.0–2.5 mm long. Petals pale yellow, 3–4 mm long. Fruits (2.5–)3.5–6.0 mm long. Styles 1.0–3.5 mm long. Seeds 0.8–1.4(–1.5) mm long, oblong-elliptic in outline, slightly longer than wide, the surface with a fine, netlike or honeycomb-like pattern of ridges and pits, reddish brown. 2n=16, 32, 40.

This species is probably more common in Missouri than herbarium specimens indicate.
