Flora of North America species comparison

several to many (ca. 3–20+), clustered, erect to ascending, branched or unbranched, solid, usually densely stellate-canescent.

usually few to many, clustered, sprawling or decumbent to ascending, rarely erect, not rooting, solid, glaucous, proximally usually stellate-puberulent, sometimes glabrous, distally glabrous.

cauline, evenly arrayed on stem, usually similar in size, shape;

stipules linear-lanceolate to ovate, 2–9 × 1–3 mm, widest above base, width sometimes exceeding stem diam.;

petiole 0.6–3(–9) cm, 1/2–3 times as long as blade, apex often with pulvinus;

blade orbiculate or reniform to flabelliform, unlobed and margins coarsely crenate to shallowly or deeply lobed, 1–7 × 1–7 cm, usually wider than long, base truncate or cordate, apex rounded, surfaces stellate-hairy.

basal and cauline, basal leaves 9 or fewer or deciduous;

stipules lanceolate, (2–)3–5(–6) × 0.5–1.5 mm;

petioles of basal and proximal cauline leaves 6–14 cm, 3–4 times as long as blades, reduced distally to 1/2 times to as long as blades;

blade reniform-orbiculate, palmately 5(–7)-lobed, deeply incised, 2–6(–8) × 2–6(–8) cm, glaucous, surfaces glabrous or minutely stellate-puberulent, lobes shallowly dentate, more deeply divided on distal leaves, margins entire, distalmost sometimes linear, unlobed.

erect, infrequently ascending, usually spiciform, dense or open, calyces overlapping or not, branched or unbranched, 2–20+-flowered, proximal flowers scattered, usually more congested distally, not notably elongate in flower, not 1-sided, (1.5–)3–25 cm, usually longer in fruit;

bracts linear to ovate-lanceolate or oblong, undivided, 2-fid, or divided, 2–8(–12) mm, not involucrelike, distal entire to 2-fid, stipulelike, proximalmost not involucrelike, divided to base, much shorter than to nearly equaling calyx.

ascending, open, calyces not conspicuously overlapping except sometimes in bud, usually unbranched, 3–10(–20)-flowered, elongate, 1-sided, 8–20 cm, axis curved between flowers, sometimes zigzag in appearance;

bracts linear to lanceolate, distinct or connate and 2-fid, 5 mm, proximal divided to base, distal often undivided, shorter than to equaling pedicels.

1–4(–5) mm;

involucellar bractlets (2 or)3, 2–10 mm, shorter to slightly longer than calyx.

2–3(–10) mm;

involucellar bractlets absent.

usually bisexual, infrequently unisexual and pistillate;

calyx 4–12 mm, densely to sparsely stellate-puberulent to long-bristly;

petals usually pale pink to pink-lavender, rarely white, veins not conspicuously whitened, 5–17 mm;

staminal column 4–7 mm, hairy;

anthers white to pale pinkish or pale yellow;

stigmas (4–)6 or 7(–10).

bisexual or unisexual and pistillate, plants gynodioecious;

calyx 5–10 mm, enlarging in fruit, hairy, hairs scattered, minute, stellate and sometimes capitate, glandular;

petals pink to pink-purple, pale-veined at least when dry, pistillate (7–)9–12 mm, bisexual 15–20(–25) mm;

staminal column 4–7 mm, stellate-hairy;

anthers pale yellow or pinkish to white;

stigmas 6–8.

1–2 mm.

2 mm.

4–7 mm diam.;

mericarps usually (4–)6 or 7(–10), (1.5–)2–2.5 mm, glabrous, sides usually smooth, thin, margins and back usually lightly reticulate-veined, transversely corrugated, back usually with medial, raised line, not pitted, mucro absent.

5–7 mm diam.;

mericarps 6–8, 3–3.5 mm, roughened, sides reticulate-veined and deeply pitted, back reticulate-veined and glandular-puberulent, mucro 0.3–1 mm.
