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, shrub], [glabrous or] hairy. Leaf: petioled to subsessile; blade generally unlobed (to palmate-lobed), generally dentate. Inflorescence: flowers 1–several in leaf axils; flowering stalks often jointed; bractlets 0. Flower: petals pale- to orange-yellow [white]; stigmas head-like. Fruit: segments generally 5–15, indehiscent, side walls firm, persistent, beaks generally 2, prominent. Seed: 1 per segment, not enclosed by net-veined envelope.Key to Sida
150 species: tropics, subtropics, especially America. (Greek: used by Theophrastus for other plant, applied to these by Linnaeus) [Fryxell 1988 Syst Bot Monogr 25:373–412] Sida abutifolia Mill. reported as possibly naturalized in California.
Stellate-puberulent. Stem: 3–10 dm, stiff, straight, branches ascending. Leaf: blade 2.5–9 cm, toothed especially in upper 1/2, puberulent, much paler abaxially, generally glabrous adaxially. Inflorescence: flowers 1 in leaf axils. Flower: calyx 5–7 mm, 10-ribbed at base, puberulent; petals (4)7–9 mm; filament tube 2 mm, hairy; styles 10–14, stigmas head-like. Fruit: 4–5 mm diam, glabrous.
2n=14,28. Uncommon. Disturbed places, fields; generally < 300 m. Great Central Valley; native to tropics. In California, evidently collected only in 1953, 1964, so may be extirpated. Aug–Oct [Online Interchange]
