Herbs moderately to densely villous throughout, also glandular puberulent, especially distally. Stems erect, moderately robust, often branched at base, 5–20 (–38) cm. Leaves: proximalmost usually clustered near base; blade narrowly lanceolate, 1.5–3 (–4.5) × 0.2–0.6 cm, base narrowly cuneate, margins undulate-serrate, apex acuminate. Flowers opening near sunrise; floral-tube 1.3–3 mm, usually pubescent on proximal 1/2 inside; sepals 2.2–3.8 mm, reflexed separately; petals (2.2–) 3–4 mm, each with 1–several red dots basally; fila­ments 0.5–1 mm, anthers 0.4–0.5 mm, pollen with less than 5% of grains 4-pored or 5-pored; style 3.2–4.1 mm, stigma surrounded by anthers at anthesis. Capsules (18–) 26–50 × 0.8–1.2 mm; pedicel 0–2 mm. Seeds 1–1.1 × 0.4 mm. 2n = 28.


Phenology: Flowering Apr–Jun.
Habitat: Sandy soil on open or brushy slopes and flats, usually sagebrush scrub or pinyon-juniper woodlands.
Elevation: 900–3000 m.
