Herbs densely strigillose, often also glandular puber­ulent, especially distally, or sometimes glandular puberulent only and then glabrate, sometimes also villous near base. Stems usually erect, sometimes decumbent, slender, wiry, usually many-branched, to 50 cm. Leaves: proximalmost not clustered near base; blade linear to very narrowly elliptic, 0.8–3.5 × 0.1–0.3 cm, base cuneate or attenuate, margins sparsely serrulate, apex acute. Flowers opening near sunrise; floral tube 1.6–2.7 mm, usually moderately to sparsely pubescent inside on proximal 1/2, rarely glabrous; sepals 1.6–4 mm, reflexed in pairs; petals 2.1–4.2(–4.5) mm, each ± with 2 red dots basally; episepalous filaments 0.9–2(–2.2) mm, epipetalous filaments 0.5–1.3 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 15–45 × 0.8–1.3 mm; subsessile. Seeds 0.6–0.8 × 0.3–0.4 mm. 2n = 28.

Discussion

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

P. H. Raven (1969) determined that Camissonia strigulosa is a self-compatible tetraploid and autoga­mous; it is closely related to C. benitensis, C. contorta, C. integrifolia, and C. lacustris.
