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
Biennial, perennial herb. Stem: erect. Leaf: petiole long; blade ± palmate-lobed. Inflorescence: spike, raceme, in panicle or not; bractlets 5–11, fused at base, <= sepals. Flower: showy, > 3 cm, pink, white, red, purple or yellow; petals notched distally; anthers near top of filament tube, below; stigmas thread-like. Fruit: segments 16–40, falling from axis, indehiscent, each with an upper, empty chamber and a lower, 1-seeded chamber, beak 0.
60 species: eastern Mediterranean to central Asia. (Greek: remedy, strength; ancient name) [Fryxell 1988 Syst Bot Monogr 25:68–70]
Unabridged etymology: (Greek: alke, remedy, or alce, strength; ancient name for this mallow)
Unabridged references: [Zohary 1963 Israel J Bot 12:1–26]
Stem: generally 1–2.5 m, generally unbranched, pithy; stellate-hairy, ± glabrous in age. Leaf: blade generally 7–15(20) cm, cordate or ovate to ± round, weakly palmate-5–7-lobed, stellate-hairy. Inflorescence: generally dense, generally branched in age; bracts generally not leaf-like; bractlets 6–9, <= sepals, widely triangular, fused at base. Flower: ± sessile, 8–10(12) cm diam; calyx tomentose; stigmas generally 20–40. Fruit: disk-like; segments 20–40, ± 6 mm, horseshoe-shaped, thin, flat, back channeled, winged, hairy.
2n=42. Uncommon. Disturbed places; especially < 1100 m. San Francisco Bay Area, Southwestern California; perhaps native to Asia Minor. Occasionally escaped from cultivation. Jun–Aug [Online Interchange]
