Flora of North America species comparison

single, erect, usually branched distally, solid, both short-stellate-puberulent and long soft bristly-hairy, hairs erect.

single or clustered, erect, rarely rooting at base, unbranched or distally branched, proximally usually solid, sometimes hollow in age, base glabrous, coarsely stellate-hairy to long-bristly, or glabrate, hairs usually becoming appressed, simple or stellate.

basal, early-deciduous, and cauline;

mid to distal stem stipules divided into 2–5 filiform or linear segments, involucrelike, 10+ × 1 mm;

petiole (4–)6–20(–50) cm, usually 1/2 times to as long as blade;

basal leaf blades orbiculate, unlobed, 1–2.5 × 1–2.5 cm, base cordate, margins crenate, apex rounded;

cauline leaf blades orbiculate, palmately 5–7-lobed, (1–)2–6 × (1–)2–6 cm, lobes linear distally, sometimes 3-toothed or -lobed, then midtooth or lobe much longer than laterals, margins entire, surfaces bristly-puberulent.

basal and cauline, basal sometimes deciduous, cauline 3+;

stipules usually deciduous, linear to lanceolate, 4–6(–14) × 0.5–1(–2) mm;

petioles of basal and proximal leaves (5–)7–10(–35) cm, 3–5 times as long as blades, reduced distally, distalmost leaves sometimes subsessile;

blade cordate or reniform-orbiculate, 3–10(–15) × 3–10(–15) cm, base cordate, apex rounded, lobe apex often acute, surfaces glabrous or sparsely hairy, hairs minute, simple, forked, or stellate, proximal usually shallowly palmately 5–7(–9)-lobed, sometimes unlobed with margins crenate;

midstem more deeply (3–)5–9-lobed, lobes again palmately or pinnately lobed, distalmost unlobed or 3(–5)-lobed, segments unlobed or deeply lobed, narrow.

erect, dense, calyces overlapping, occasionally short-branched, clusters to 10-flowered, subumbellate to elongate in age, not 1-sided;

bracts linear or filiform, palmately 2–7-lobed, 8–12 mm, lobes linear, usually becoming involucrelike, 1–2.5 cm, subequal to or longer than calyx.

erect, usually spiciform, sometimes subcapitate, congested in bud, dense, calyces sometimes conspicuously overlapping in flower and sometimes in fruit, to open and elongate, few-branched or unbranched, 10–20+-flowered, flowers opening and closing sequentially from base to apex, sometimes 3–10 open on same day, not leafy-bracted, not 1-sided, (1.5–)10–30 cm, elongating in flower or fruit;

bracts linear to linear-lanceolate, undivided to 2-fid, proximal sometimes divided to base, 4–6(–7) mm, sometimes exceeding flower buds, usually equaling or longer than pedicels, shorter than calyx.

1–3 mm, (short branches may easily be mistaken for pedicels);

involucellar bractlets absent.

1–3(–10) mm;

involucellar bractlets absent.

bisexual;

calyx 8–12 mm, not much accrescent, lobes often with narrow purple line or spot at lobe base inside, outer surface bristly-hairy and stellate-puberulent, seldom densely glandular, multicellular hairs usually few or absent;

petals dark pink to deep purple, veins often paler, darker patch sometimes at base, 20–35 mm;

staminal column 4–6 mm, hairy;

anthers sessile on rim, white;

stigmas 5 or 6.

bisexual or unisexual and pistillate, plants gynodioecious;

calyx usually green, 3.5–10 mm, usually lightly reticulate-veined, glabrous or densely, uniformly stellate-puberulent or bristly, surface often obscured;

petals usually overlapping, pink or pink-lavender to dark rose-pink or magenta, not notably pale-veined, pistillate 5–10 mm, bisexual 8–15(–20) mm;

staminal column 4–6(–9) mm, hairy;

anthers white to pinkish;

stigmas 6–9.

2 mm.

1.5–2.5 mm.

6–7 mm diam.;

mericarps 5 or 6, sometimes pinkish when fresh, 2.5 mm, glabrous, back minutely hairy, back and sides reticulate-veined, back with prominent midvein, not pitted, mucro absent.

4–7 mm diam.;

mericarps 6–9, 2–3 mm, sparsely glandular-puberulent, sometimes glabrous, not stellate-hairy, back and margins rounded, smooth or slightly reticulate-veined or pitted, infrequently prominently roughened at least on margins and/or back, mucro 0.1–0.7 mm.
