Camissoniopsis ignota


Higher Taxonomy
Family: OnagraceaeView DescriptionDichotomous Key
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.

Genus: CamissoniopsisView DescriptionDichotomous Key


Habit: Annual to subshrub, from taproot. Leaf: basal and cauline, alternate, simple, generally narrowly lanceolate or narrowly elliptic to ovate. Inflorescence: spike, nodding in bud, generally flower from basal-most to distal nodes. Flower: opening at dawn; sepals 4, reflexed singly or in fused pairs; petals 4, yellow, fading red, generally with 1+ red basal spots, with no ultraviolet pattern; stamens 8, longer opposite sepals, anthers attached at middle, pollen grains 3-angled except in polyploid taxa at 20×; ovary chambers 4, stigma +- spheric or hemispheric, exceeding anthers and cross-pollinated or +- = anthers and self-pollinated. Fruit: 4-angled at least when dry, generally proximally thick, contorted or curled 1--5 times, or straight, not swollen by seeds, sessile. Seed: in 1 row per chamber, narrowly obovoid, flattened, dull brown-black.
Species In Genus: 14 species: California, Arizona, Oregon, Baja California. Etymology: (Greek: like Camissonia) Note: Polyploidy and self-pollination have predominated in evolution of genus. Incl in Camissonia in TJM (1993).

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.
