Common Name: EVENING-PRIMROSE FAMILY Habit: 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. Genera In Family: 22 genera, +- 657 species: worldwide, especially western North America; many cultivated (Clarkia, Epilobium, Fuchsia, Oenothera). Note:Gaura moved to Oenothera. Fuchsia magellanica Lam. naturalized in northern California. eFlora Treatment Author: Warren L. Wagner & Peter C. Hoch, family description, key to genera, treatment of genera by Warren L.

Common Name: SUN CUP Habit: 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. Etymology: (L.A. von Chamisso, French-born German botanist, 1781--1838) Note: 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). eFlora Treatment Author: Warren L.

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.
