We provide the provisional checklist of vascular plants of Alaska as the most complete starting list for an update to the Flora of Alaska. Names on this list have not yet been vetted by the Taxonomic Committee. Once vetted by the Taxonomic Committee, the list will be updated and vetted status indicated. However, even names vetted by the Taxonomic Committee are subject to future changes as no checklist is truly final. For information on the development of the provisional list, please see the About the Provisional Checklist section.
The Provisional Vascular Checklist contains 2,777 accepted names of vascular genera, species, microspecies, and infraspecies that are known to occur in Alaska. The checklist also includes 67 provisionally accepted names. We include 6,212 synonyms and spelling variants and 217 misapplied names. This checklist is searchable by both all names and accepted names. The “Status” column indicates the relationship of the name to the accepted name.
Use the filters and search boxes below to explore the checklist. The “All Names” field includes all names that have been applied or misapplied in Alaska for each accepted name. The “Accepted Name” field shows accepted vascular taxa. The “Status” field shows the relationship between the applied/misapplied name and accepted name. The source field contains links for the material from which a name was accepted.
Both name fields can be searched at once by typing queries in the main search block above the table. Other fields can be search for in the main search block as well. For example, life-forms can be searched for by typing “tree”, “shrub”, “dwarf shrub”, “forb”, “graminoid”, etc., into either the main search block or the “Growth Form” field.
To download the results of a query, select “All” in the number of rows and then click the desired download format. Queries that display thousands of rows may take several minutes to load.

About the Provisional Checklist
The checklist has been developed from lists of plants occurring in Alaska from Checklist of the Panarctic Flora, University of Alaska Museum Herbarium (ALA), and University of Alaska Anchorage Herbarium (UAAH). The checklist includes synonyms and names that have been misapplied for taxa in Alaska. We initially compiled all specimens collected in Alaska and stored across numerous herbaria into a single data file. From the compiled specimen data, we generated a list of all names that have been applied in Alaska. Additional names for non-native plants and rare plants were incorporated from AKEPIC and the ACCS rare plants data portal, respectively. We then reconciled our list of applied names in the state to the following taxonomic reference sources listed below to determine accepted names, misapplied names, and synonyms. Although order of priority for taxonomic sources varied by group, we generally gave priority to monographic work by taxonomic specialists, the Panarctic Flora Checklist, and the Flora of North America North of Mexico, in that order. The citations listed below are ordered alphabetically, rather than by priority.
