Camissonia campestris
Brittonia 16: 284. 1964.
Herbs glabrous, villous, strigillose, or glandular puberulent, especially distally, sometimes glabrous distally. Stems erect or decumbent, slender, wiry, usually well-branched, 5–25(–50) cm. Leaves: proximalmost not clustered near base; blade linear to narrowly elliptic or narrowly oblanceolate, 0.5–2.5(–3) × 0.1–0.15(–0.5) cm, base attenuate, margins sparsely serrulate to coarsely serrate, apex acuminate. Flowers opening near sunrise; floral tube 1.5–5.5 mm, ± densely villous on proximal 1/2 inside; sepals 3.5–8(–12) mm, reflexed in pairs; petals (3.5–)5–15.5 mm, each usually with 1 or 2 red dots basally; episepalous filaments (1.4–)2.1–5.5 mm, epipetalous filaments (0.7–)1.2–3.2 mm, anthers 1–2.4 mm, pollen with less than 5% of grains 4- or 5-pored; style (3.2–)4–12(–15) mm, stigma well exserted beyond anthers at anthesis. Capsules 20–43 × 0.7–1.5(–2) mm; subsessile. Seeds 0.8–1.6 × 0.4–0.6 mm.
Discussion
Subspecies 2 (2 in the flora).
