Characteristics

Subshrubs, 0.4–1 m, sparsely branched in proximal 1/2. Stems usually procumbent and ascending, hairs appressed, (6–)8–10-rayed, sublepidote. Leaves: stipules persistent, lanceolate, subfalcate, 4–6 × 1–1.5 mm, apex acute; petiole 10–25 mm; blade wide-ovate to ovate, unlobed or rarely with 2 obscure lateral lobes halfway from base, (1.8–)3–4(–5.5) × (1–)1.5–3(–4.5) cm, usually slightly (ca. 1.2 times) longer than wide, 2 times longer than petiole, base cordate to rounded or truncate, margins crenate-dentate, apex rounded, surfaces hairy, hairs scattered, appressed, (6–)8–10-rayed, sublepidote. Inflorescences axillary solitary flowers; floral bracts absent. Pedicels 3–5(–10) mm in flower, to 2 mm in fruit; involucellar bractlets basally adnate to calyx for 2–3 mm, deltate-cordiform in distal 4–6 mm, abruptly narrowed, 8–10 × 3–5 mm, shorter than calyx lobes, apex acute. Flowers: calyx connate 1/3–1/2 its length, broadly campanulate, lobes slightly auriculate at base, 11–12 mm, to 13–17 mm in fruit, surface hairy, hairs scattered, appressed, stellate-lepidote; corolla wide-spreading, golden yellow to pale orange-yellow, 30 mm diam., petals obovate, conspicuously asymmetrically lobed, 12–16 × 10–15 mm, exceeding calyx by 7–8 mm; staminal column 4 mm, glabrous; style 12–16-branched. Schizocarps 9–10 mm diam.; mericarps readily shed from calyx, 12–16, 4–6 × 4–6 × 1–1.5 mm, widely-notched, with 1 conspicuous, distally-directed, medial-apical cusp 1.5–2.3 mm and 2 distal-apical, contiguous, flattened, obtuse cusps 1 mm, surface sparsely hairy, hairs both erect and appressed, rigid, simple on apex and minute, stellate on dorsal 1/3, sides smooth. Seeds 2–3 mm. 2n = 36.
