Discussion | Variety beneolens occurs from Harney and Malheur counties, Oregon, to Modoc County, California, and to Elmore, Owyhee, and Twin Falls counties, Idaho, and Elko and Humboldt counties, Nevada. Plants are particularly common on the vertical sides of the river canyons that cut through the Owyhee Plateau. The variety also barely enters the Idaho Batholith on volcanic intrusions along the South Fork of the Boise River. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
