ONAGRACEAE EVENING-PRIMROSE FAMILY

Warren L. Wagner & Peter C. Hoch, family description, key to genera; treatment of genera by Warren L. Wagner, except as noted

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

CAMISSONIA SUN CUP
Annual, from taproot; rosette generally ± 0. Leaf: cauline, alternate, simple, generally linear to narrowly elliptic. Inflorescence: bracted; spike or raceme, nodding in bud, erect in fruit, flowers only at distal nodes. Flower: radial, generally opening at dawn; sepals 4, reflexed singly or in pairs; petals 4, yellow, generally fading red, often with red basal spots; stamens 8, longer ones opposite sepals, anthers attached at middle, pollen grains 3-angled except in polyploid taxa, at 20×; ovary chambers 4, stigma hemispheric, generally > anthers and cross-pollinated, or ± = anthers and self-pollinated. Fruit: ± cylindric, straight to wavy, distorted by seeds at maturity, dehiscent throughout most of its length; pedicel ± 0 or <= 2(15) mm, 0 or shorter in flower. Seed: in 1 row per chamber, narrowly obovoid, smooth (minutely pitted), glossy.
12 species: western North America (especially California Floristic Province), 1 South America. (L.A. von Chamisso, French-born German botanist, 1781–1838) [Wagner et al. 2007 Syst Bot Monogr 83:1–240] Polyploidy and self-pollination have predominated in evolution of genus. Not monophyletic as treated in TJM (1993); segregates moved to Camissoniopsis, Chylismia, Chylismiella, Eremothera, Eulobus, Neoholmgrenia, Taraxia, Tetrapteron (Wagner et al. 2007).

Key to Camissonia

C. campestris (Greene) P.H. Raven
NATIVE
Slender; hairs 0, coarse, or glandular. Stem: decumbent or erect, 5–25(50) cm, peeling. Leaf: 5–30 mm, linear to narrowly elliptic or narrowly oblanceolate, minutely to coarsely serrate. Flower: hypanthium 1.5–5 mm; sepals 3–8(12) mm, remaining adherent in pairs; petals (3.5)5–15 mm, yellow fading ± red, basal spots (1)2; stigma exceeding anthers. Fruit: 20–43 mm, 0.7–2 mm wide, alternately narrow and swollen by seeds, straight or wavy, ± sessile. Seed: 0.8–1.6 mm.
2n=14. Cross-pollinated. Subspecies intergrade extensively. [Online Interchange]
