Herbs, perennial, or subshrubs, (0.4–)1–1.5 m, sparsely horizontally branched, usually with 1 main stem and usually unbranched secondary branches in distal 1/2. Stems erect, canescent, hairs radially symmetric, appressed, not lepidote, with both larger (4-or)5-rayed hairs and minute 4–8-rayed stellate hairs, sometimes shed in age. Leaves: stipules persistent, narrowly lanceolate, subfalcate, 5–6 × 1 mm, apex acuminate; petiole 10–25(–70) mm; blade wide-ovate to ovate-lanceolate to nearly lanceolate on distal stem, unlobed, usually 3–5 × 1.5–3 cm, 1.3–1.7 times longer than wide, 2.5–3.5 times longer than petiole, base usually rounded to wide-cuneate, margins dentate to sharply dentate, apex acute to acuminate, surfaces stellate-hairy, hairs 4–8-rayed, adaxial surface also with simple hairs. Inflorescences axillary solitary flowers at first, later elongated terminal racemes, flowers sometimes appearing clustered on reduced racemes, these terminating each branch; floral bracts 2-fid, 4 × 2 mm. Pedicels 0.5–2 mm, increasing by 0.5–1 mm in fruit; involucellar bractlets adnate basally to calyx for 1–2 mm, narrowly lanceolate to lanceolate, subfalcate, 4–6 × 0.5–1 mm, 1/2 length of calyx lobes, apex acute. Flowers: calyx connate 1/4–1/2 its length, rotate, 6–8 mm, to 7–9 mm in fruit, surface hairy, hairs sparse, tufted, stellate, 2–6-rayed, and few, simple, marginal hairs mixed with minute, dense, stellate, 5–8-rayed hairs; corolla wide-spreading, yellow to orange-yellow, 15–18 mm diam., petals obovate, slightly asymmetrically lobed, 6–8 × 7 mm, exceeding calyx by 3–4 mm; staminal column 2–3 mm, stellate-puberulent; style 9–12-branched. Schizocarps 5.5–8 mm diam.; mericarps tardily shed from calyx, 9–12, 3–4 × 1.8–2 × 1 mm, conspicuously notched, without proximal cusp or with small mucro to 0.1 mm and with 2 conspicuous divergent distal-apical cusps (0.5–)1–1.5 mm, dorsal surface hirsute, hairs simple, rigid, 0.1–1 mm, mixed with simple and stellate, smaller hairs, lateral faces ± glabrous, conspicuously ribbed and thickened. Seeds 1.5–2 mm. 2n = 24.
