Of conservation concern. Eriogonum molestum is infrequent to occasionally common in the San Bernardino (San Bernardino County) and San Jacinto (Riverside County) mountains, and in scattered mountain ranges of San Diego County, California. It is easily confused with the perennial E. nudum var. pauciflorum. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Eriogonum allenii is restricted to the Appalachian shale barrens of Virginia (Alleghany, Augusta, Bath, Botetourt, Craig, Frederick, Highland, Montgomery, and Shenandoah counties) and West Virginia (Greenbrier, Monroe, and Pendleton counties), where it is local and infrequent, and found in four geographic areas of concentration. The plants are protected at The Nature Conservancy’s Slaty Mountain site in Monroe County, West Virginia, and in Douthat State Park in Bath County, Virginia. The species occasionally is cultivated.
