Key to Geraniaceae
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.Key to Erodium
± 74 species: temperate America, Eurasia, northern Africa, Australia. (Greek: heron, from bill-like fruit) [Fiz et al. 2006 Syst Bot 31:739–763] Some cultivated for forage, dyes; "beak segments" sometimes called "awns" elsewhere. Erodium macrophyllum moved to genus California.
