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.

Eriogonum brachypodum is variable in overall shape, peduncle length, and shape and size of involucres and flowers. Spreading plants with longish peduncles and narrow involucres occur in southwestern Utah and adjacent portions of Nevada and Arizona; this is the “parryi” phase of the species. Typical E. brachypodum is low and flat-topped, with the inflorescence up to 10 dm across. The involucres are usually sessile and campanulate rather than turbinate. The two phases intergrade completely and a taxonomic distinction is not warranted. Dried plants of the typical phase often are used as decorations. The species is common and even weedy in places. It occurs from Churchill and Pershing counties, Nevada, south through Mono and Inyo counties to eastern Kern and San Bernardino counties, California, then eastward through Nevada (Clark, Esmeralda, Lincoln, Mineral, and Nye counties) into southwestern Utah (Beaver and Washington counties) and northwestern Arizona (Mohave County). It is much more common in the Mojave Desert than in the Great Basin. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
