Herbs annual, caulescent, strig­illose or glabrous, also often glandular puberulent, especially distally; from a sparsely branched taproot. Stems un­branched or with many ascending branches arising near base, erect, 10–50 cm. Leaves in a basal rosette and cauline, basal 1–2 (–4) × 0.2–0.6 cm, petiole 0.2–1 (–1.5) cm, blade ovate to obovate or narrowly elliptic; cauline 1–4 × less than 0.1 cm, sessile, blade linear or filiform. Flowers usually 1–3 opening per day near sunrise; buds without free tips; sepals 1.5–2 mm; petals bright-yellow, fading pink, obcordate to obovate, 3–5 (–7) mm; filaments 1–2 mm, anthers 0.5–1 mm; style 1–2 mm, stigma surrounded by anthers at anthesis. Capsules ellipsoid-rhombic to subglobose, 4-angled, 4–6 (–10) × 1.5–3 mm, stipe 0–4 mm, valve midrib raised at distal end, indehiscent or tardily dehiscent distally; sessile. Seeds clustered in each locule, ovoid, surface minutely papillose, 1 × 0.5 mm. 2n = 14.


Phenology: Flowering Apr–Jun(–Aug).
Habitat: Prairies, open woodlands, open rocky and sandy sites, roadsides.
Elevation: 0–400 m.
