Herbs densely strigillose, inflorescence often also glandular puberulent. Stems usually well branched from base, 3–30 cm, usually flowering proximally and distally. Leaves cauline, mostly clustered near base, reduced distally, 0.5–2.5 × 0.3–1.5 cm; petiole 0.5–2 cm; blade oblanceolate or narrowly oblanceolate, margins entire or sparsely denticulate. Inflorescences erect. Flowers opening at sunset; floral tube 0.5–1.9 mm, strigillose in proximal 1/2 inside; sepals 0.8–1.8 mm; petals white, fading pinkish, 0.8–1.3 mm; filaments 0.3–1.3 mm, epipetalous filaments shorter than episepalous, sometimes apparently abortive, anthers 0.5–0.8 mm; style 1.2–3.2 mm, sparsely short-villous near base, stigma 0.5–0.6 mm diam., surrounded by anthers at anthesis. Capsules cylindrical and thickened proximally, spreading, contorted, subterete, 10–25 × 0.8–1.2 mm, regularly but tardily dehiscent. Seeds monomorphic, gray, 1.1–1.2 × 0.4 mm, finely reticulate. 2n = 14.
Phenology: Flowering May–early Jun.
Habitat: Clay or sandy soils, slopes, flats, sagebrush, rabbitbrush, bitterbrush or saltbush shrublands.
Elevation: 700–1800 m.
Distribution
Calif., Colo., Idaho, Nev., Oreg., Utah, Wash., Wyo.
Discussion
P. H. Raven (1969) determined Eremothera minor to be self-compatible and autogamous. The name Sphaerostigma nelsonii A. Heller is superfluous and pertains here.
Selected References
None.
