Treatment appears in FNA Volume 7. Treatment on page 523. Mentioned on page 524.

Plants glandular or eglandular, not canescent. Basal leaves: lateral lobes (3–) 5–9 pairs, margins usually coarsely dentate to incised, rarely crenate or pinnatifid. Cauline leaves: lobes oblong to lanceolate, margins dentate to denticulate. Racemes glandular or eglandular. Fruiting pedicels ascending to divaricate, (3–) 5–10 (–12) mm. Fruits straight or curved inward. 2n = 14.


Phenology: Flowering late Jun–Aug.
Habitat: Alpine, stream banks, disturbed sites, roadsides, meadows, sagebrush and juniper communities, open woods, rocky cliffs, sandy areas, talus slopes
Elevation: 900-2900 m
