Genus: ErodiumView DescriptionDichotomous Key

Common Name: STORKSBILL, FILAREE
Habit: Annual, perennial herb. Leaf: simple to pinnately compound, cauline opposite; blade lanceolate to reniform in outline, puberulent or short-hairy, base cordate to truncate. Inflorescence: umbel. Flower: radial; stamens 5, free, alternate 5 scale-like staminodes. Fruit: mericarp body indehiscent, fusiform, 1-seeded, base sharply pointed, top generally with 1 pit on each side of beak segment, pits subtended by 1--4 ridges or not; beak segments stiffly hairy adaxially, generally twisted.
Species In Genus: +- 74 species: temperate America, Eurasia, northern Africa, Australia. Etymology: (Greek: heron, from bill-like fruit) Note: Some cultivated for forage, dyes; "beak segments" sometimes called "awns" elsewhere. Erodium macrophyllum moved to genus California.

Erodium cygnorum Nees
WAIF
Habit: Annual. Stem: decumbent to ascending, 1--3 dm, +- soft-hairy. Leaf: deeply 3--5-divided; lower 4--8 cm; blade < petiole, ovate in outline, lower 2 divisions > 10 mm wide, wedge-shaped. Flower: sepals 5--13 mm, tip glabrous to puberulent; petals +- > sepals, pink, purple, or blue. Fruit: body 5--6 mm, pits +- transversely elliptic, subtended by 1--2 hairy or glabrous ridges; style column 5--6 cm. Chromosomes: 2n=20, 40, 60.
Ecology: Uncommon. Abandoned fields, disturbed sites; Elevation: < 500 m. Bioregional Distribution: SCo; Distribution Outside California: native to Australia. Flowering Time: Mar--Jul Note: Last collected in 1925, "in citrus orchard at Corona, CA," suggesting treatment as an historical, agricultural weed might be more appropriate.
