Abstract: An original SEINet checklist was compiled as part of the Flora of the Sonoran Desert Network Project, a project of the Vegetation Mapping program at the Sonoran Desert Network (http://science.nature.nps.gov/im/units/sodn/index.cfm). It was derived from baseline inventory data, herbarium records, the phylogenetic and ecological literature, and agency study records. In 2024 Max Licher reviewed many of the existing vouchers, made some annotations/corrections, updated nomenclature, and also eliminated many non-vouchered taxa from the list that are not generally known from the area or represented in adjacent floristic studies (Upper Verde River, Dean Horse Ranch State Park, Verde Valley Botanical Area).
