Herbs usually glabrous or densely strigillose, rarely villous (mostly proximally), also often sparsely glan­dular puberulent, especially distally. Stems erect, slender, wiry, often branched, 2–15 cm. Leaves: proximalmost not clustered near base; blade linear or linear-filiform, 1–3 × 0.04–0.1 cm, base attenuate, margins subentire, apex acute. Flowers opening near sunrise; floral-tube 1.3–2 mm, glabrate; sepals 1.5–2.5 mm, reflexed separately; petals 1.5–3.6 mm, without red dots at base; filaments 0.5–1 mm, anthers 0.3–0.6 mm, pollen with less than 5% of grains 4-pored or 5-pored; style 1.5–3 mm, stigma surrounded by anthers at anthesis. Capsules 15–28 × 0.6–1 mm; pedicel 0–2 mm. Seeds 0.7–0.8 × 0.4 mm. 2n = 28.


Phenology: Flowering Apr–Jun.
Habitat: Sandy soils, usually with sagebrush scrub.
Elevation: 100–2700 m.

Distribution

Ariz., Calif., Colo., Idaho, Mont., Nev., N.Mex., Oreg., Utah, Wash., Wyo.
