Annual to perennial herb (to tree). Leaf: cauline or basal, alternate, opposite, or whorled, generally simple and toothed (to pinnately compound); stipules 0 or generally deciduous. Inflorescence: spike, raceme, panicle, or flowers 1 in axils; bracted. Flower: generally bisexual, generally radial, often opening at either dawn or dusk; hypanthium generally prolonged beyond ovary (measured from ovary tip to sepal base); sepals 4(2–7); petals 4(2–7, rarely 0), often fading darker; stamens 2 × or = sepals in number, anthers 2-chambered, opening lengthwise, pollen interconnected by threads; ovary inferior, chambers generally as many as sepals (sometimes becoming 1), placentas axile or parietal, ovules 1–many per chamber, style 1, stigma 4-lobed (or lobes as many as sepals), club-shaped, spheric, or hemispheric. Fruit: capsule, loculicidal (sometimes berry or indehiscent and nut-like). Seed: sometimes winged or hair-tufted.
22 genera, ± 657 species: worldwide, especially western North America; many cultivated (Clarkia, Epilobium, Fuchsia, Oenothera). [Wagner et al. 2007 Syst Bot Monogr 83:1–240] Gaura moved to Oenothera. Fuchsia magellanica Lam. naturalized in northern California. —Scientific Editors: Robert Patterson, Bruce G. Baldwin.

Key to Onagraceae
Perennial herb from tuber-tipped rhizomes or stolons. Leaf: opposite, petioled, entire to toothed; stipules present, occasionally deciduous. Inflorescence: raceme or panicle. Flower: hypanthium present; biradial; sepals 2, often reflexed, deciduous after flower (along with other flower parts); petals 2, erect; stamens 2, pollen yellow, grains shed singly; ovary chambers 1–2, stigmas maturing before anthers. Fruit: indehiscent, generally club-shaped, bur-like with hooked hairs. Seed: 1 per chamber, adhering to inner fruit wall.
8 species: northern hemisphere. (Greek: Circe, the enchantress) [Wagner et al. 2007 Syst Bot Monogr 83:78–81] Often self-pollinated.
