Treatment appears in FNA Volume 10.

Herbs densely villous, also densely glandular puberulent, especially in inflorescence. Stems 5–20 cm. Leaves not especially clustered toward base, mostly evenly distributed, 2–5 × 0.3–1.5 cm; petiole 0–1.5 cm; blade narrowly elliptic to narrowly lanceolate or lanceolate, sometimes oblanceolate proximally, margins sparsely serrulate to sometimes sinuate-toothed. Inflorescences leafy. Flowers: floral-tube 3–5 mm; petals white, 4–5 mm. Capsules usually curved outward or slightly contorted, 0.9–1.4 mm diam. near base. Seeds dimorphic.


Phenology: Flowering late May–Aug(–Sep).
Habitat: Sandy or gravelly slopes and flats, sagebrush, shadscale, and rabbitbrush shrublands, pinyon-juniper woodlands.
Elevation: 1200–2000 m.

Distribution

Calif., Nev.

Discussion

Subspecies intermedia is somewhat invariant; it bridges the morphological gap between subspp. alyssoides and boothii. It occurs in Nevada from southeastern Churchill and southern Lander counties south throughout Nye and Esmeralda counties and in southern Mineral County, in northeastern Inyo County, California, and in the Kingston Range, northeastern San Bernardino County, California.
