Common Name: MALLOW FAMILY
Habit: 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).
Genera In Family: 266 genera, 4025 species: worldwide, especially warm regions; some cultivated (e.g., Abelmoschus okra; Alcea hollyhock; Gossypium cotton; Hibiscus hibiscus). Note: 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).

Common Name: BUSH-MALLOW
Habit: Generally shrub, generally erect; hairs sparse to dense, stellate (stalked or sessile), simple, and glandular. Leaf: petioled; blade unlobed to 3--7-lobed, coarsely or shaggy-hairy to tomentose. Inflorescence: head- to panicle-like, flowers generally > 1 in leaf axils; bracts leaf-like or not, in involucre or not; bractlets 3, free, linear to lanceolate, persistent. Flower: calyx 5-lobed; petals 5, pale pink-purple or white (often +- purple when dry); petals generally > calyx, fused at base; stamens open prior to stigma maturation; style branches 5--14. Fruit: segments 5--14, 2--5 mm, separating, dehiscent, smooth, top hairy, beak 0. Seed: 1 per segment, brown to black.
Species In Genus: 12 species: California, northwestern Mexico. Etymology: (Greek: malakos, soft, thamnos, shrub) Note: Malacothamnus foliosus (S. Watson) Kearney reported but evidently not documented for California.

Common Name: CHAPARRAL MALLOW
Habit: Plant 1--5 m, branches slender; hairs sessile (stalked), white, sparse to velvety, woolly. Leaf: blade 2--8 cm, lobes 0 or 3--5, shallow to deep, stellate hairs +- equally dense abaxially, adaxially. Inflorescence: panicle-like; flowers generally 3--7 per node; leaf-like bracts few; flowering stalks < 1.5 cm, bractlets to 1 cm, 1/2 as wide, 1/2 calyx. Flower: buds acuminate; calyx 4--7(11) mm, 1/2 as wide, lobes acute, < 2 × tube; petals 1--3 cm; filament column < petals. Fruit: segments < 5 mm, deeply notched, brown. Chromosomes: 2n=34.
