Sphaeralcea munroana
MUNRO'S DESERT-MALLOW

Higher Taxonomy
Family: MalvaceaeView DescriptionDichotomous Key

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).

Genus: SphaeralceaView DescriptionDichotomous Key

Common Name: GLOBEMALLOW
Habit: 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.
Species In Genus: +- 50 species: arid America. Etymology: (Greek: globe mallow, from fruit shape) Note: Polyploidy, intermediates common.
