Eriogonum polycladon is widely distributed from near Needles, San Bernardino County, California (where not found since the 1930s), eastward to western Texas, and from southern Utah throughout much of central and southern Arizona into western and southern New Mexico. It is found also in the Mexican states of Chihuahua, Durango, and Sonora. It can be locally common and occasionally weedy, especially in southeastern Arizona and southwestern New Mexico. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.) |
