Herbs perennial, usually procumbent, many branched, 20-50 cm tall, scabrous. Stipule small, ovate-lanceolate, 4-6 × 2-3 mm; petiole 3-12 cm, stellate velutinous; leaf blade reniform, rarely 5-7-lobed, 1-3 × 1-4 cm, papery, abaxially sparsely stellate puberulent, adaxially sparsely velutinous, base cordate, margin minutely denticulate, apex rounded. Flowers usually 3-4-fascicled, axillary, rarely solitary on stem. Pedicel 2-5 cm, sparsely stellate puberulent. Epicalyx lobes lanceolate, 2-5 × 1-1.5 mm, stellate puberulent. Calyx campanulate, 5-6 mm, stellate puberulent, 5-lobed, lobes triangularly acuminate. Corolla white to pinkish, 10-12 mm in diam.; petals obcordate, 9-15 × 3-5 mm, apex notched; claw bearded. Filament tube stellate puberulent. Style branches 13-15. Fruit flat globose, 5-6 mm in diam.; mericarps 12-15, abaxially smooth, angles rounded, puberulent. Seeds reniform, ca. 1 mm in diam., reticulate or not. Fl. summer.
Herbs, usually annual, rarely biennial or perennial, 0.2–0.6 m, trailing stems sometimes to 1 m, sparsely hairy, hairs usually simple and stellate. Stems trailing to ascending, hairs usually both simple and stellate. Leaves: stipules persistent, narrowly to ovate-triangular, 3–5(–6) × 2–3 mm; petiole on proximal and midstem leaves to 3 times as long as blade, usually 2 times longer on distal leaves, sparsely hairy, hairs simple and stellate; blade cordate to broadly reniform, unlobed or broadly and very shallowly 5-lobed, 1–5 × 1–5 cm, base cordate, margins finely crenate or dentate, apex rounded, surfaces glabrous or sparsely stellate-hairy. Inflorescences axillary, flowers solitary or in 2–10-flowered fascicles (compact cymes), obviously stalked. Pedicels 0.4–0.5 cm, to 1–2.4 cm in fruit, slender and flexible, sparsely hairy, hairs simple and stellate; involucellar bractlets distinct, not adnate to calyx, linear to lanceolate, 3–4 × 0.5 mm, shorter than calyx, margins entire, surfaces sparsely ciliate and stellate-puberulent. Flowers: calyx 3–5 mm, 5–6 mm in fruit, lobes incompletely enclosing mericarps, mostly hispid, hairs both simple and stellate, conspicuously long-ciliate, lobes not obviously veined; petals pale pink or nearly white, drying pinkish or whitish, or faded, veins not darker, 3–6 mm, subequal to slightly longer than calyx; staminal column 1–1.5 mm, glabrous; style 10- or 11-branched; stigmas 10 or 11. Schizocarps 5–7 mm diam.; mericarps 10 or 11, 1.5–2 mm, margins sharply angled, toothed, not winged, lateral faces radially veined, apical surface strongly rugose-reticulate ridged, surface glabrate or sparsely stellate-puberulent. Seeds 1–1.5 mm. 2n = 42.
Herb, up to 200 mm tall. Leaves undivided to very shallowly lobed. Epicalyx bracts much narrower than sepals. Petals shorter than 15 mm, usually not more than twice as long as calyx. Mericarps 9-16, distinctly reticulately ridged on back, glabrous, edges often slightly raised but neither toothed nor overlapping adjoining mericarps. Flowers white or pale mauve.
