Excluded Taxa

The Excluded Taxa list includes taxa that have been have been listed as occurring in Washington State, but are not considered to be a part of the state's flora by the Washington Flora Checklist authors. Taxa are excluded from the checklist for the following reasons:

» Erroneous reports for the state based on misidentified specimens or a literature error.

» Unverified reports not backed by a voucher specimen or reliable literature reference.

» Names that have been have been erronously applied to taxa that occur Washington State. These names still apply to taxa that occur outside Washington and cannot be treated as nomenclatural or taxonomic synonyms.

Additional expanatory notes are provided with most taxa. Misapplied names are linked to the appropriate accepted name for Washington.
