Stems glabrous, rarely obscurely retrorsely hairy at proximal nodes. Leaves glabrous. Flowers: stamens included or reaching orifice, longer pair rarely exserted. 2n = 16.


Phenology: Flowering Mar–Jul.
Habitat: Sagebrush shrublands, pinyon-juniper woodlands, pine forests.
Elevation: 1200–2900 m.

Distribution

Ariz., Calif., Colo., Idaho, Nev., N.Mex., Utah, Wyo.

Discussion

Some specimens of var. eatonii from the Schell Creek Mountains in White Pine County, Nevada, have the longer pairs of stamens prominently exserted and stems obscurely puberulent. Records from Lake County, Colorado, Oneida County, Idaho, and Carbon County, Wyoming, probably are based on plants that were seeded along highways or pipelines.

Selected References

None.

Lower Taxa

None.
