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, subshrub, canescent to stellate-hairy, with longer hairs or not. Leaf: petioled; blade lance-linear to triangular, entire to deeply dissected. Inflorescence: raceme-like (flowers clustered in bract axils) or panicle; bractlets (0)1–3, inconspicuous, generally deciduous, thread-like. Flower: petals obovate, white, lavender, pink, rose-pink, salmon- or red-orange, or apricot; filament tube hairs 0 or stellate, anthers generally ± yellow or ± purple; stigmas head-like. Fruit: segments 9–17, 1–2-seeded, below indehiscent, strongly net-veined, above dehiscent, smooth. Seed: gray, black, or brown.Key to Sphaeralcea
± 50 species: arid America. (Greek: globe mallow, from fruit shape) Polyploidy, intermediates common.

Subshrub, coarsely canescent. Stem: erect, < 21 dm. Leaf: blade 25–55 mm, ovate-triangular, 3- or 5-veined, gray-green, crenate, base cordate, tip ± truncate to acute; lobes 3. Inflorescence: raceme-like below, dense panicle above. Flower: calyx 6–8 mm; petals 10–12 mm, red-orange to lavender; filament tube ± 6 mm, anthers yellow. Fruit: segments 10–16, 4.5–5 mm, 2.5 mm wide, truncate-conic, dehiscent part < 3 mm, ± 60% of segment. Seed: 1–2 per segment, brown or black.
