The genus Eriogonum is one of North America's largest and most complex group of plants. Found primarily in the western United States where its members are a common feature of the landscape, its overall range is from Alaska to central Mexico and from the Pacific coast to the Atlantic coast. The genus is composed of eight subgenera and 226 species. The purpose of the dissertation is to present an abbreviated revision of the genus following the style format of the North American Flora series. Brief taxonomic descriptions and keys are provided along with details of each taxon's geographical distribution and type location. A complete monographic revision will be presented at a later date.
