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, biennial, perennial herb, shrub, ± glabrous to stellate-hairy. Stem: erect, herbaceous to soft-woody. Leaf: petioled; blade ovate to lanceolate, shallowly to deeply 5–7(9)-lobed or lobes 0, generally crenate to dentate. Inflorescence: raceme-like or generally flowers 1[several] in leaf axils; bractlets 3, fused generally 1/2. Flower: generally showy; petals pink, purple, rose-purple or white, dark-veined or not; anthers near top of filament tube, below, generally not clustered; stigmas linear, on inner side of style branches. Fruit: ± disk-like; segments (6)10–19, indehiscent, smooth or variously ribbed and/or hairy, outer edges generally rounded, beak 0. Seed: 1 per segment, generally not firmly enclosed by, readily separating from fruit wall, reniform, glabrous.Key to Lavatera
± 12 species: Europe, especially Mediterranean, Asia, Africa. (Lavater brothers, 17th century Swiss physicians, naturalists) [Ray 1998 Novon 8:288–295] Most species transferred to Malva, primarily on molecular data (Ray 1995, 1998); other commonly cultivated species that may escape including Lavatera cashmiriana Camb., Lavatera thuringiaca L.
Unabridged references: [Ray 1995 Plant Syst Evol 198:29–53; Ray 1998 Novon 8(3): 288–295]
Generally bristly. Stem: erect, generally woody at base, generally 1–2 m, tomentose in youth, hairy to ± glabrous in age. Leaf: densely stellate-tomentose; petioles to 10 cm; blade generally to 15 cm, lower 3–5-lobed, acute to obtuse, upper oblong-ovate to lanceolate, often ± 3-lobed. Inflorescence: raceme-like or flowers 1 in leaf axils; flowering stalks 2–7 mm; bractlets widely ovate. Flower: petals 2–3 cm. Fruit: segments 17–19, puberulent or glabrous.
2n=42. Disturbed places; < 400 m. South Coast (Laguna Canyon, Orange Co.); native southwestern Europe, Mediterranean; widely cultivated. Rarely escapes cultivation. May–Jun [Online Interchange]
