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, glabrous or generally sparsely stellate-hairy; plant with bisexual or only pistillate flowers. Stem: prostrate to erect, ± hollow. Leaf: blade toothed to lobed or dissected, bases symmetric. Inflorescence: flowers 1 in leaf axils or in axillary or terminal clusters; flowering stalks longer in fruit; bractlets subtending calyx 3, persistent, linear to thread-like. Flower: calyx lobes > tube, acuminate; petals generally > calyx, white to ± purple (drying darker); filament tube included, anthers at tip; styles > filament tube, stigmas head-like. Fruit: segments generally 9–22 or 25–35, unarmed, glabrous, generally ± black, sides fragile, outer edges, back ridged or net-veined.Key to Eremalche
3 species: southwestern United States, northwestern Mexico. (Greek: lonely mallow, from desert habitats) [Andreasen 2005 Conservation Genet 6:399–412]
Unabridged etymology: (Greek: eremi, lonely, and malache, mallow, lonely mallow, from desert habitats)
Unabridged references: [Fryxell 1988 Syst Bot Monogr 25:151–155]
Stem: prostrate to decumbent, < 50 cm, finely stellate-hairy. Leaf: generally 1–2.5 cm wide, 3–5-lobed; lobe tips entire or 3-toothed. Inflorescence: flowers 1 in leaf axils, scattered on stem, occasionally near stem base, ± = subtending leaves; bractlets 3–7 mm. Flower: bisexual; calyx 4–7 mm, lobes 3–5 mm, 1.5–2.5 mm wide; petals 4–5.5 mm, white or pale pink-purple. Fruit: segments 9–13, 1.4–1.8 mm, ± wedge-shaped in ×-section, margins rounded, outer wall cross-ridged.
2n=20,40. Desert scrub; < 1500 m. San Joaquin Valley, Inner South Coast Ranges, Channel Islands (probably extirpated), San Gabriel Mountains, White and Inyo Mountains, Desert; Arizona, Nevada, Utah, northern Baja California. Mar–May [Online Interchange]
