Annual to tree; generally with stellate hairs, often with bristles or peltate scales; juice generally mucilage-like; bark fibrous. Leaf: generally cauline, alternate, petioled, simple [palmate-compound], generally palmate-lobed and/or veined, generally toothed, evergreen or not; stipules persistent or not. Inflorescence: head, spike, raceme, or panicle, in panicle or not (a compound panicle), or flowers >= 1 in leaf axils, or flowers generally 1 opposite a leaf or on a spur; bracts leaf-like or not; bractlets 0 or on flowering stalks, often closely subtending calyx, generally in involucel. Flower: generally bisexual, radial; sepals 5, generally fused at base, abutting in bud, larger in fruit or not, nectaries as tufts of glandular hairs at base; petals (0)5, free from each other but generally fused at base to, falling with filament tube, clawed or not; stamens 5–many, filaments fused for most of length into tube around style, staminodes 5, alternate stamens, or generally 0; pistil 1, ovary superior, stalked or generally not, chambers generally >= 5, styles or style branches, stigmas generally 1 or 1–2 × chamber number. Fruit: loculicidal capsule, [berry], or 5–many, disk- or wedge-shaped segments (= mericarps).
266 genera, 4025 species: worldwide, especially warm regions; some cultivated (e.g., Abelmoschus okra; Alcea hollyhock; Gossypium cotton; Hibiscus hibiscus). [Angiosperm Phylogeny Group 1998 Ann Missouri Bot Gard 85:531–553] Recently treated to include Bombacaceae, Sterculiaceae, Tiliaceae. Mature fruit needed for identification; "outer edges" are surfaces between sides and back (abaxial surface) of segment. "Flower stalk" used instead of "pedicel," "peduncle," especially where both needed (i.e., when flowers both 1 in leaf axils and otherwise). —Scientific Editors: Steven R. Hill, Thomas J. Rosatti.

Key to Malvaceae
Annual, perennial herb; with taproot, clustered fleshy roots, caudex, adventitious roots, or occasionally shallow rhizome. Stem: ± decumbent or generally erect, some occasionally stolon-like; erect stem, branches terminating in inflorescence. Leaf: generally fewer above, occasionally ± rosetted; petioles below generally >> petioles above; blades below generally crenate to shallowly lobed, blades above often deeply palmate-lobed or -divided; stipules generally persistent. Inflorescence: head, spike, or raceme, in panicle or not, generally more open in fruit; bracts 2, generally stipule-like, occasionally involucre-like, united at base to ± entirely; bractlets 0(3), generally not in involucel. Flower: flowers generally bisexual, protandrous, occasionally functionally unisexual (occasionally, plants with either bisexual or pistillate flowers in a given sp.); calyx lobes >= tube; petals spreading or erect, purple or rose-pink to white, generally with some pale veins, base generally also paler than tips (occasionally darker), tip ± notched or fringed, petals on pistillate flowers shorter, darker, often <= 10 mm; filament tube generally stellate-puberulent, anthers near top, in generally 2 concentric series, generally pink, ± purple, or white; stigmas linear, on inner side of style branches, conspicuous in pistillate flowers. Fruit: segments generally 5–10, indehiscent, puberulent, glandular, or glabrous, beaked or not, side walls generally ± thin. Seed: 1, generally filling chamber, reniform, glabrous.Key to Sidalcea
± 27 species: western North America: Alaska, Canada, to Mexico. (Greek: combination of Sida, Alcea, 2 other names for mallows) [Andreasen & Baldwin 2003 Amer J Bot 90:436–444; Hill 2008 J Bot Res Inst Texas 2:783–791] Some species highly variable, especially in leaves, growth stage; mature plants with fruit minimize considerable problems in identification, as does knowledge of plant base, underground parts; needs study.

Unabridged note: This treatment differs from that in TJM (1993) in addition of new taxa and in segregation as species of former, primarily inland subspecies of Sidalcea malviflora, now primarily a coastal entity.
Perennial herb 2–8 dm, from thick fibrous crown, caudex short, rhizomes generally 0. Stem: hairs stellate or bristles. Leaf: crowded near stem base; blades 2–6(8) cm wide, stellate-hairy, lower crenate to shallowly 7-lobed, upper few, lobed ± to base. Inflorescence: exceeding leaves, generally branched, (15)30–45 cm, flowers > 10. Flower: calyx 6–10 mm, densely stellate-puberulent, many hairs on margins, veins longer; petals 1–2.5 cm, pink-rose. Fruit: segment 2.5–3 mm, weakly to moderate-net-veined-pitted, glandular-puberulent, beak short.
2n=20,40. Periodically moist to dry grassy slopes or ± flat places, chaparral often with Artemisia, oaks; < 2200 m. s Sierra Nevada Foothills, Outer South Coast Ranges, Southwestern California; northern Baja California. [Sidalcea malviflora subsp. sparsifolia C.L. Hitchc.] Intergrades with Sidalcea malviflora subsp. californica, Sidalcea neomexicana; evaluation of possible infraspecific taxa, including those of C.L. Hitchc., needed. With Sidalcea neomexicana, among southernmost in genus. Mar–Jun [Online Interchange]
