Flora of North America species comparison

1–3, clustered, erect, solid, proximally hairy, hairs a mix of soft, appressed, stellate and/or longer, bristlelike, 2 mm, distally sparsely puberulent.

basal and cauline;

stipules deciduous, lanceolate, 4–7(–15) × 1–2 mm;

petioles of proximal leaves 10–20 cm, 3–4 times as long as blades, reduced distally to 1/2 times blade length;

blades: proximal orbiculate, shallowly or deeply 5–9-lobed, 5–10 × 5–10 cm, base wide-cordate to ± truncate, lobe margins coarsely crenate and dentate, apex 2–5-toothed, mid stem largest, 5–7(–9)-lobed, usually incised ± to base, 10–25 × 10–25 cm, lobe margins coarsely dentate to laciniate or entire, surfaces scabrid-hairy, hairs simple or forked, stiff;

distalmost 5–7-lobed, lobes linear, subentire, margins ciliate, surfaces glabrescent or with few hairs on abaxial veins.

usually cauline, alternate, also distichous in Krapovickasia, Malvella, Meximalva, and some species of Sida, subsessile or sessile in some Herissantia, Horsfordia, Sida, Sidastrum, and Sphaeralcea;

blade usually symmetric, asymmetric in Malvella, sometimes asymmetric in Pavonia, usually unlobed, sometimes palmately lobed or dissected, margins serrate or entire, primary veins often palmate (except in Lagunaria), without nectaries (except in Gossypium, Hibiscus, Talipariti, Thespesia, and Urena).

erect, spiciform or subcapitate, dense, calyces usually conspicuously overlapping in flower and sometimes in fruit, branched, ca. 10-flowered, flowers/calyces overlapping, not 1-sided, 3–7(–10) cm, elongated in fruit;

bracts lanceolate-elliptic, undivided, 3–8 mm, longer than pedicels, often longer than young flower buds, ± equaling calyx.

terminal or axillary, umbels, spikes, racemes, or panicles or solitary flowers;

bracts usually present.

1–2 mm, to 4 mm in fruit;

involucellar bractlets absent.

bisexual or unisexual and pistillate, plants gynodioecious;

calyx 5–9 mm, to 10 mm in fruit, margins ciliate, minutely stellate-puberulent and bristly with longer, coarser, usually pustulate hairs usually on pads, bristle hairs 1–2 mm;

petals pink to pinkish lavender, not notably whitish- or pale-veined, (5–)8–30 mm, pistillate 5–15 mm, bisexual to 20–30 mm;

staminal column 5–7 mm, hairy;

anthers white to pale pink;

stigmas (6 or)7 or 8.

bisexual or unisexual, some species with staminate or pistillate flowers, plants usually hermaphroditic, some dioecious, some monoecious;

involucel (epicalyx) present or absent;

sepals usually persistent (deciduous in Abelmoschus), 5, ± connate;

petals 5, usually distinct, adnate to staminal column and connate to each other at base, falling together, without clawlike appendage;

androgynophore absent;

androecium monadelphous, in more than 1 concentric series in Sidalcea, staminal column sometimes toothed at apex, stamens 5–many, filaments connate;

anthers 1-thecate;

staminodes absent or 5 teeth at apex of staminal column;

gynoecium syncarpous, ovary superior, 3–40-carpellate;

styles 1, branched or unbranched;

stigmas truncate, capitate, linear, or filiform, 1–2 times number of carpels.

usually schizocarps with 5–many wedge-shaped mericarps or folliclelike segments, or capsules with 3–5 cells, rarely berries (in Malvaviscus), carpels sometimes with internal protrusion dividing carpel into 2 cells, dehiscence loculicidal, rarely indehiscent.

1.8 mm.

2–30, often reniform, glabrous or hairy.

6–7 mm diam.;

mericarps (6 or)7 or 8, 2.5 mm, sparsely glandular-puberulent, margins usually sharp-edged but not winged, sides coarsely reticulate-veined to nearly smooth, back lightly reticulate-veined, usually prominently roughened at least on margins and/or back, pitted, mucro 0.5 mm.
