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.
