Clarkia rubicunda


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: ClarkiaView DescriptionDichotomous Key


Habit: Annual < 1.5 m. Stem: prostrate to erect, glabrous, often glaucous, or puberulent (hairs long, spreading). Leaf: pinnately veined; petiole < 4 cm or 0; blade 1--10 cm, linear to elliptic or ovate, entire or shallow-toothed, glabrous or sparsely puberulent. Inflorescence: spike, raceme; bracts leaf-like; axis in bud straight or recurved at tip, in flower +- straight; buds erect or not. Flower: hypanthium obconic to cup-shaped, or long, slender, generally with ring of hairs within; sepals 4, generally fused to tip in bud, reflexed at least at base, staying fused at least at tip, in 4s or 2s, or all coming free; corolla bowl-shaped to rotate, petals 5--60 mm, often lobed or clawed, lavender or pink to dark red, pale yellow, or white, often spotted, flecked, or streaked with red, purple, or white; stamens 8, in 2 like or unlike series, or 4, filaments cylindric to wider distally, subtended by ciliate scales or generally not, anthers attached at base, pollen white or yellow to blue-gray, lavender, or +- red; ovary 4-chambered, glabrous or not, cylindric, fusiform, or wider distally, generally shallowly to deeply 4- or 8-grooved, stigma lobes 4, generally prominent. Fruit: generally capsule, elongate (short, indehiscent, nut-like). Seed: generally many, rarely 1--2, 0.5--2 mm, angled, crested or not, brown, gray, or mottled.
Etymology: (Captain William Clark, 1770--1838, of Lewis & Clark Expedition) Note: Self-fertile; self-pollinated or outcrossed; on herbarium specimens, curvature of inflorescence axis in bud generally reliable, pollen color generally not.

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.
