Flora of North America species comparison

erect, base usually woody.

trailing to ascending, hairs usually both simple and stellate.

stipules deciduous, ovate, 4–5 × 2–3 mm, papery, apex acute to obtuse, sparsely stellate-hairy and ciliate;

petiole longer than blade;

blade rounded, shallowly and unequally 5–7(–9)-lobed (lobes obtuse), 5–20 × 5–20 cm, base cordate, margins crenate, apex obtuse to rounded, surfaces densely soft stellate-hairy especially abaxially.

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 in fascicles.

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

jointed distally, 0.5–1 cm, not much longer in fruit;

involucellar bractlets connate in proximal 1/3, adnate to calyx, lobes broadly ovate to round, 8 × 5–6 mm, longer than calyx, margins entire, apex acute or obtuse, surfaces stellate-hairy.

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 3–4 mm, not much enlarged in fruit, densely stellate-canescent;

petals rose to lavender with 5 darker veins, dark purple basally, 15–20 mm, length 4–5 times calyx, apex emarginate;
