Inflorescence: cyme, raceme, panicle, cluster, or flowers 1; bractlets on pedicel ("pedicel bractlets") generally 0--3(many), subtended by bract or generally not. Flower: generally bisexual, radial; hypanthium free or fused to ovary, saucer- to funnel-shaped, subtending bractlets ("hypanthium bractlets") 0--5, alternate sepals; sepals generally 5; petals generally 5, free; stamens (0,1)5--many, anther pollen sacs generally 2; pistils (0)1--many, simple or compound, ovary superior to inferior, styles 1--5. Fruit: 1--many per flower, achene (fleshy-coated or not), follicle, drupe, or pome with generally papery core, occasionally drupe-like with 1--5 stones. Seed: generally 1--5 (per fruit, not per flower). Genera In Family: 110 genera, +- 3000 species: worldwide, especially temperate; many cultivated for ornament, fruit, especially Cotoneaster, Fragaria, Malus, Prunus, Pyracantha, Rosa, Rubus.

Habit: Annual, inconspicuous, soft-hairy, nonglandular. Stem: spreading to erect. Leaf: palmately lobed. Inflorescence: few-flowered cluster, axillary, +- hidden by sheathing stipules; pedicel bractlets 0. Flower: hypanthium +- urn-shaped, bractlets 0 or 4; sepals 4; petals 0; stamen generally 1, pollen sac 1, horseshoe-shaped; pistil generally 1, ovary superior, style attached near base. Fruit: hypanthium encasing achene, not hardened.

Aphanes occidentalis (Nutt.) Rydb.
NATIVE Stem: generally 2--10 cm. Leaf: generally 3--12 mm; stipules widely ovate, deeply lobed; petiole generally 1--5 mm; blade generally 2--5 mm, +- round, main lobes 3, > 2/3 to base, again toothed or lobed. Flower: 0.5--2 mm; hypanthium bractlets 0 or < 0.5 mm; sepals 0.2--0.6 mm. Fruit: achene +- 1 mm, ovoid. Ecology: Seasonally moist grassland, chaparral, woodland; Elevation: 30--1200 m. Bioregional Distribution: NW, CaRF, SNF, ScV, CW, SW; Distribution Outside California: to Washington, Baja California. Flowering Time: Mar--May Note: Highly variable; several +- separable forms. Synonyms: Alchemilla occidentalis Nutt. Unabridged Note: Highly variable, with several +- separable forms. Relation to species of Mediterranean unclear. northern NCo plants with more hidden flowers resemble Aphanes microcarpa (Boiss. & Reut.) Rothm. of eastern North America, Europe. Aphanes arvensis L. (larger plants) weedy in Oregon, Washington.

MAP LEGEND View all CCH records 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.
