Flora of North America species comparison

erect or ascending, glabrous or sparsely hairy, hairs both simple and stellate.

erect, sparsely hirsute proximally, stellate-hairy distally, hairs often pustulose.

stipules persistent, lanceolate to ovate-triangular, 3–5(–8) × 3 mm;

petiole 1/2 to 1 1/2 times as long as blade, pubescent in adaxial groove, otherwise glabrous;

blade reniform to suborbiculate-cordate, unlobed or shallowly 3–7-lobed, sinuses to 1/2 to base, (2–)5–10(–14) × (2–)5–10(–14) cm, base cordate to ± truncate, lobes semicircular to oblong, margins crenate, apex rounded to wide-acute, surfaces glabrous or sparsely hairy, hairs simple or stellate.

stipules deciduous, lanceolate, slightly falcate, 5(–10) × 1–2.5 mm, ciliate;

petioles of lower leaves 1.5–2.5 times as long as blade, reduced distally to 1/2 blade length, stellate-hairy;

blade 2–8 × 2–8 cm, base cordate to somewhat truncate, those most distal sometimes wide-cuneate, surfaces stellate-hairy, proximal leaf blades cordate-orbiculate, margins crenate to dentate, shallowly lobed, apex rounded, distal leaf blades deeply (3–)5-lobed, lobe margins obtusely dentate or pinnatifid, apex narrowly acute.

axillary, flowers solitary or in 2–4-flowered fascicles, long-stalked.

axillary, flowers solitary or distal flowers in racemes.

1–2.5 cm, 1–4.5 cm in fruit, much longer than calyx, glabrous or sparsely stellate-hairy;

involucellar bractlets distinct, sometimes adnate to calyx in basal 1 mm, oblong-lanceolate to elliptic or narrowly obovate, reticulate-veined, (3–)4–5(–7) × 2.5–4 mm, shorter than calyx, margins entire, surfaces glabrous, sparsely ciliate.

conspicuously jointed distally, 1.4–2 cm, not much longer in fruit;

involucellar bractlets distinct, not adnate to calyx, ovate or ovate-deltate to obovate, narrowed to base, 5–8(–12) × 2.5(–5) mm, shorter than calyx, margins entire, surfaces stellate-hairy or glabrate.

calyx reticulate-veined, 5–6 mm, to 10 mm in fruit, lobes incompletely enclosing mericarps, stellate-puberulent;

petals pink to purple or reddish purple with darker veins, usually drying blue, (12–)16–30(–45) mm, length 2 1/2–3(–4) times calyx;

staminal column 5 mm, minutely, retrorsely stellate-puberulent;

style 10–12-branched;

stigmas 10–12.

calyx 9–12(–15) mm, lobes enclosing mericarps, stellate-hairy;

petals usually bright pink, rarely white, 20–35 mm, length 2.5–3 times calyx;

staminal column 9–10 mm, sparsely stellate-hairy;

style 18–20-branched;

stigmas 18–20.

1.5–2.2 mm.

brown, 2.5 mm.

7 mm diam.;

mericarps 10–12, 2–2.5 mm, margins sharp, not winged, sides thin and papery, with radiating veins, surface strongly to obscurely reticulate-wrinkled, usually glabrous, sometimes sparsely hairy.

4–8 mm diam.;

mericarps 18–20, black, 2.4–2.8 mm, apical surface and margins rounded, smooth or faintly ridged, glabrous or sparsely hairy.
