Herbs annual, strigillose, villous, or glandular puberulent. Stems usually unbranched, sometimes branched from base, 3–45 cm. Leaves primarily in basal rosette, cauline poorly developed or absent, 1–18 × 0.5–3.5 cm; petiole 0.5–6.5 cm; blade pinnately lobed or lateral lobes greatly reduced or absent, sometimes mixed on same plant, terminal lobe narrowly ovate to ovate or elliptic, 1–6.5 × 0.5–3.3 cm, margins irregularly dentate to subentire, oil cells on abaxial surface inconspicuous or conspicuous, pale yellowish brown or dark brown. Racemes nodding, elongating in fruit. Flowers opening at sunrise; buds with or without subapical free tips less than 1 mm; floral tube 1–4 mm, sparsely villous or glabrous inside; sepals 1.2–5 mm; petals bright yellow, often with red dots near base, fading pale yellow or yellowish orange, 1.5–5.5(–8) mm; stamens unequal, filaments of antisepalous stamens 1.2–6 mm, those of antipetalous ones 0.5–4 mm, anthers 1–2.5 mm, ciliate or glabrous; style 3–11 mm, stigma surrounded by anthers at anthesis. Capsules ascending, clavate, 8–50 mm; pedicel 4–20 mm. Seeds 1–2 mm.
