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.) |
Eriogonum tomentosum is widespread in a series of somewhat disjunct populations mainly on the coastal plain. It supposedly is found in North Carolina, but no specimens have been seen. An unnumbered J. K. Small collection from Miami, Florida (Nov. 1904, NY), surely is mislabeled. A Cuthbert collection (30 Jul. 1876, MICH) from Augusta may be from a garden, as that location is well out of the known range of the species. Mark Catesby made the first collections (BM-Sloane, OXF) of the species in the 1720s. T. Walter (1788) ascribed his specimen (BM-Walter) to a European species of Saxifragaceae.
