Eremalche parryi subsp. kernensis

Higher Taxonomy
Family: MalvaceaeView DescriptionDichotomous Key
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: EremalcheView DescriptionDichotomous Key

Habit: 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.

All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
