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. Genera In Family: 22 genera, +- 657 species: worldwide, especially western North America; many cultivated (Clarkia, Epilobium, Fuchsia, Oenothera). Note:Gaura moved to Oenothera.

Habit: Annual from taproot. Leaf: basal and/or cauline, alternate, simple to 2-pinnate. Inflorescence: spike. Flower: opening at dusk; sepals 4, reflexed singly or in pairs; petals 4, generally white, pink, or rarely red, without spots or ultraviolet reflective area, fading red; longer stamens opposite sepals, anthers attached at middle, pollen grains 3-angled; stigma hemispheric, generally > anthers and cross-pollinated or +- = anthers and self-pollinated. Fruit: straight to coiled, sessile. Seed: in 1 row per chamber, obovoid to oblanceoloid, minutely pitted, sometimes those near base of fruit coarsely papillate. Etymology: (Greek: desert + Oenothera) Note: Incl in Camissonia in TJM (1993). eFlora Treatment Author: Warren L.

(Note: any qualifiers in the taxon distribution description, such as 'northern', 'southern', 'adjacent' etc., are not reflected in the map above, and in some cases indication of a taxon in a subdivision is based on a single collection or author-verified occurrence).
MAP LEGEND View all CCH records All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
