Herbs sparsely strigillose or glabrate, more densely so distally. Stems usually erect, sometimes decumbent, slender, wiry, usually many-branched, to 30 cm. Leaves: proximalmost not clustered near base; blade linear, 1–3 × 0.1–0.3 cm, base cuneate or attenuate, margins usually entire, rarely with 1 or 2 small teeth, apex acute. Flowers opening near sunrise; floral tube 1.5–2.5 mm, moderately to sparsely pubescent inside on proximal 1/2; sepals 1.6–4 mm, reflexed in pairs; petals 2–4.2 mm, each ± with 2 red dots basally; episepalous filaments 0.9–2.1 mm, epipetalous filaments 0.5–1.4 mm, anthers 0.3–0.6 mm, pollen with usually less than 10% of grains 4-pored; style 2.3–4.8 mm, stigma surrounded by anthers at anthesis. Capsules 45–60 × 0.8–1.3 mm; subsessile. Seeds 1–2 × 0.4–0.5 mm. 2n = 28.

Flowering Apr–May. Sagebrush slopes; 700–1000 m; Calif.; Mexico (Baja California).

Camissonia integrifolia is known in the flora area from central to southern California, west of the Sierra Nevada.

P. H. Raven (1969) determined that Camissonia integrifolia is a self-compatible tetraploid and autoga­mous. The species forms sterile natural hybrids with C. strigulosa, to which it is presumably most closely related.
