Stems erect, 20–70 cm, glabrous and glaucous distally, usually puberulent basally. Leaves: petiole to 10 mm; blade lanceolate to elliptic or ovate, 1.5–4 cm. Inflorescences open racemes, sometimes branched, axis straight; buds pendent. Flowers: floral-tube 2 mm; sepals reflexed together to 1 side; corolla rotate, petals oblanceolate to obovate, 8–12 mm, claw tapered, shorter than blade, apex entire; stamens 8, unequal, outer anthers orange-red, inner smaller, paler. Capsules 15–35 mm; subsessile. Seeds brown, 1–1.5 mm, tuberculate (especially on raphe), crest inconspicuous. 2n = 36.


Phenology: Flowering Apr–May.
Habitat: Oak woodlands, chaparral.
Elevation: 0–1000 m.

Distribution

Calif., Mexico (Baja California)

Discussion

Clarkia delicata is known in California only from the Peninsular Ranges, mainly in San Diego County with outliers in Riverside and San Bernardino counties, and in northern Baja California, Mexico. Because of its limited range, it is listed as rare by the California Native Plant Society. It is a tetraploid derived from hybri­dization between C. epilobioides and C. unguiculata.
