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
Annual to subshrub. Leaf: generally opposite proximally (or clustered in axils), generally ± fine-toothed; veins generally obscure. Inflorescence: generally raceme, bracted. Flower: radial or rarely ± bilateral; sepals 4, erect; petals 4, notched; stamens 8, anthers attached at middle, pollen grains generally shed in 4s, cream-yellow; ovary chambers 4, stigma generally club-like, occasionally 4-lobed. Fruit: straight, cylindric to club-like. Seed: generally in 1 row per chamber, generally with white, deciduous hair-tuft.Key to Epilobium
165 species: worldwide except tropics. (Greek: upon pod, from inferior ovary) [Raven 1976 Ann Missouri Bot Gard 63:326–340; Wagner et al. 2007 Syst Bot Monogr 83:81–95] Incl Boisduvalia, Zauschneria. Most taxa polyploid; many with anthers ± = stigma self-pollinated; many hybrids. Taxa with alternate leaves moved to Chamerion.
Annual 0.4–6.5 dm, taprooted, ± gray spreading-hairy, peeling proximally. Leaf: opposite only near base (where glabrous), ± sessile, 5–45 mm, ± lance-linear, hairy. Inflorescence: glandular, bracts leaf-like. Flower: generally cleistogamous; hypanthium 0.4–1 mm; sepals 0.7–2 mm; petals 1–3.2 mm, pink or white; stigma club-like or rarely 4-lobed. Fruit: sessile, 8–14 mm, cylindric, beaked, flexible, dehiscent to base; axis disintegrating. Seed: 0.9–1.6 mm, netted; hair-tuft 0.
