Treatment appears in FNA Volume 7. Treatment on page 697. Mentioned on page 698.

Cauline leaves: blade oblanceolate to broadly lanceolate, margins (at least proximal ones) lyrate-pinnatifid or runcinate. Flowers: sepals 9–16 mm; petals 10–20 mm, claw 5–10 mm; gynophore 10–28 mm, pubescent basally. Fruits 3–9 cm; ovules 22–38 per ovary. Seeds 2.5–4 mm. 2n = 28, 56.


Phenology: Flowering Apr–Sep.
Habitat: Prairie hills, chalk bluffs, shale slopes, talus, sagebrush and mixed shrub communities, pinyon-juniper areas, selenium-rich areas, barren hillsides, sandstone breaks and cliffs, dry sandy or gravelly washes, sand dunes, canyon bottoms, soils derived from limestone, sandstone, basaltic, and volcanic rocks
Elevation: 200-2500 m

Discussion

Subshrubby or shrubby forms of var. pinnata were recognized as a distinct var. or subsp. inyoensis. Although such growth forms occur primarily in southern California, western Nevada, and southwestern Utah, they occur sporadically throughout the species range, especially in desert habitats with sand dunes.
