Herbs, annual, 0.2–0.8 m. Stems usually erect or ascending, rarely decumbent, wide-branched, glabrous or sparsely stellate-hairy distally. Leaves: stipules persistent, broadly lanceolate, 4–5 × 2–3 mm; petiole 2–3(–4) times as long as blade; blade suborbiculate-cordate or reniform, mostly shallowly 5–7-lobed or angled, 2–8(–10) × 2–8(–10) cm, base cordate (to nearly truncate), lobes deltate or rounded, margins evenly crenate, apex rounded to broadly acute, surfaces glabrous or hairy, especially at base, hairs simple and stellate. Inflorescences axillary, flowers solitary or in 2–4-flowered fascicles. Pedicels 0.2–0.4 cm, usually to 1 cm in fruit, shorter than calyx; involucellar bractlets distinct, not adnate to calyx, linear to filiform, (1–)2–3 × 0.3 mm, shorter than calyx, margins entire, surfaces glabrous or slightly ciliate. Flowers: calyx 3–4.5 mm, to 7–8 mm in fruit, glabrous or stellate-hairy, lobes wide-spreading outward in fruit, orbiculate-deltate, reticulate-veined, apex often abruptly acuminate, short-ciliate or not, scarious in fruit; petals white to pale lilac, drying pinkish or whitish, or faded, veins not darker, 3–4.5(–5) mm, subequal to or only slightly longer than calyx, glabrous; staminal column 1.5 mm, glabrous; style 10- or 11-branched; stigmas 10 or 11. Schizocarps 6–7 mm diam.; mericarps 10 or 11, 2–2.5 mm, apical face strongly reticulate-wrinkled, sides appearing strongly, radially ribbed, margins sharp-edged, toothed, narrowly winged, surface glabrous or hairy. Seeds 1.5–2 mm. 2n = 42.
Hierba, decumbente a ascendente, ligeramente pu- bescente o glabrescente. Hojas 2.5 –10.5 X 2.5 –12 cm, orbiculares o reniformes, onduladas a ligera- mente 5 –7-lobuladas, de otra forma crenadas, escasa y generalmente estrellado-pubescentes en el haz, sin nectarios foliares. Infls. axilares, de 1– 4 fls.; pedice- los más cortos que el cáliz. Fls. con calículo de 3 brácteas separadas, 2.5 – 3 mm, filiformes; cáliz 3 – 4 mm (a 7– 8 mm en fr.), lobulado hasta ca. 1/2; pétalos lavanda (a menudo blancos en CR), 4 – 5 mm; estilos múltiples, los estigmas decurrentes. Frs. esquizocár- picos, 6 –7 mm de diám., obloides, los mericarpos ca. 10 (en CR), romos en el ápice, rugosos dorsalmente, levemente alados en los ángulos (en forma de herradura), densamente pubescentes, indehiscentes; semilla 1 por mericarpo, ca. 1.5 – 2 mm, glabra.
"Much like nos. 5 [Malva neglecta Wallr.] and 6 [Hypericum boreale (Britton) E. P. Bicknell]; pedicels mostly less than 10 mm, even in fr; cal strongly accrescent and reticulate-veiny in fr; fr as in no. 6, but the margins of the carpels narrowly winged; 2n=42. Native of the Mediterranean region, widespread as a weed in c. and w. U.S., and local with us."
Annual, prostrate-procumbent herb. Stem up to 60 cm long, sparsely stellate pubescent to glabrescent. Leaves orbicular, cordate at base, 2-4 cm long, 2-6 cm broad, upper surface with generally sparsely simple or 2-rayed hairs or glabrous, lower surface more hairy, simple, 2 rayed and stellate, often 3-7-lobed, crenate-serrate; stipules lanceolate to ovate, 2-5 mm long, 1-2 mm broad, ciliate margined; petiole 3-17 cm long, simple and stellate hairy, more so to wards the apex. Flowers axillary usually fascicled, compact, rarely solitary; pedicel 3-5 mm long, usually not visible, stellate pubescent, in fruit a few up to 10 mm long, glabrescent. Epicalyx segments linear, c. 7 mm long, 1 mm broad, stellate pubescent. Calyx 3-5 mm long, densely stellate pubescent, free nearly to the middle, accrescent in fruit, c. 1 cm long. Petals white, pinkish at the tips, usually shorter than or equal to sepals, occasionally longer, slightly notched above, glabrous, oblong, slightly narrow at base. Staminal column glabrous c.2 mm long. Fruit discoid, (3-) 5-6 mm across, mericarps (8-) 10, dorsally with raised reticulate venation, radially transversely ribbed, 1.5-2 mm across in all direction margin winged. Seed 1 mm long and broad, brown, black glabrous.
Prostrate or decumbent herb; stems usually under 40 cm long, hairy, longitudinally sulcate. Leaf-lamina 1-5 x 1-5 cm, reniform or nearly suborbicular in outline, obtusely 3-5-angled, crenate or crenate-serrate, glabrous or sparsely hairy; petiole often longer than the lamina, usually with a few hairs near the apex. Flowers mauve or pale pink to white, subsessile, in few-flowered clusters in the leaf-axils; pedicels 2-4 mm long. Bracts of epicalyx linear, deciduous. Calyx 2-5 mm long, accrescent and enclosing the fruit; lobes ovate or roundish, mucronate, spreading. Petals scarcely exceeding the calyx; claw glabrous. Fruit glabrous or occasionally hairy; mericarps with acutely-angled reticular dorsal ridges and slightly raised and sharp lateral angles.
Prostrate or decumbent herb. Petals scarcely exceeding calyx, with glabrous claws. Mericarps with acutely angled reticular dorsal ridges, meeting laterally in somewhat raised sharp edge. Flowers mauve or pale pink to white.
Found in waste places and in parks and gardens, but never a serious pest.
Madagascar; S. Africa. Native of Europe and Asia, naturalised in many countries as a weed of cultivation and now almost cosmopolitan.
