Plants annual, with minute, tuberous body; periderm absent. Stems 2–10 cm. Leaves: basal leaf-blades linear to narrowly lanceolate, 1–5 × 0.05–0.2 cm; cauline leaves sessile, blade linear, 1–3 cm. Inflorescences multibracteate; proximalmost bract 5–10 mm, leaflike, distal bracts 1 mm or less, reduced to membranous scales. Flowers 10–12 mm diam.; sepals 1.5–2.5 mm; petals white, pink, or candy-striped, 6–10 mm; ovules 6. Seeds (1–) 6, 1–2 mm, shiny and smooth; elaiosome 1 mm or less. 2n = 12.


Phenology: Flowering early Mar.
Habitat: Selaginella mats and crevices of cliffs and rock faces in Great Basin sagebrush and ponderosa pine belt
Elevation: 200-1200 m
