Flora of North America species comparison

usually erect, rarely prostrate, base not woody.

trailing to ascending, hairs usually both simple and stellate.

stipules deciduous, broadly lanceolate to ovate, 4–4.5 × 2 mm, papery, sparsely puberulent, ciliate, hairs simple;

petioles of proximal leaves to 3.5 times as long as blade, usually equaling blade on distal portion of stems, stellate-hairy to glabrate;

blade suborbiculate, 4–10 × 4–10 cm, base cordate, surfaces sparsely stellate-hairy, 3–4 mm, equaling to shorter than calyx, margins entire, apex obtuse, surfaces stellate-hairy.

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.

axillary, flowers solitary or in 2–10-flowered fascicles (compact cymes), obviously stalked.

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.

calyx (4–)7–8 mm, to 11 mm in fruit, densely soft stellate-hairy;

petals pale pink to white, sometimes drying bluish, usually with 3 darker veins, 10–16 mm, length 2 1/2–4 times calyx;

staminal column 5 mm, densely stellate-hairy;

style 7–10-branched;

stigmas 7–10 (same number as locules).

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;

brown, 2.5–2.7 mm.

1–1.5 mm.

9–12 mm diam., style base often expanded and disclike;

mericarps 7–10, 4 × 4 mm, margins rounded, smooth, usually cross-ridged, surfaces usually glabrous.

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.
