Stems erect, 30–100 cm, strigil­lose. Leaves: petiole to 15 mm; blade linear to lanceolate, 2–8 cm. Inflorescences open racemes, axis recurved at tip in bud; buds pendent. Flowers: floral tube 1–4 mm; sepals reflexed together to 1 side; corolla rotate to bowl-shaped, petals purplish to pale pink, lavender, or bright pink to magenta, often red-flecked, broadly to narrowly fan-shaped, 10–25 mm, shallowly to deeply 2-lobed; stamens 8, unequal, outer anthers lavender, inner ones smaller, paler. Capsules 10–25 mm. Seeds brown, 1 mm, minutely scaly to puberulent, crest inconspicuous.

Discussion

Subspecies 3 (3 in the flora).

Clarkia biloba is most closely related to C. lingulata, which is derived from C. biloba subsp. australis. Some populations of C. biloba subsp. brandegeeae (originally described as a form of C. dudleyana) are morphologi­cally very similar to some individuals of C. dudleyana but the two taxa are separated geographically, have different chromosome numbers, and hybrids between them are sterile.

Selected References

None.
