Abstract: The following checklist is based on herbarium records (primarily from the University of Nevada Las Vegas, Glen Canyon NRA, and Brigham Young University), published and unpublished literature, and recent field collections and observations by Walter and Laura Fertig and John Spence. Status within Rainbow Bridge NM is either confirmed present (Pres) with an herbarium record, photograph, or recent observation; historical (Hist) - not observed since 1970; or re-ported (Rep) in the literature. Population Size ranges from common (com) to uncommon (unc) or rare. The source is the basis for a record in the Rainbow Bridge flora and may be an herbarium specimen, literature citation, or observation. The year documented is the earliest year in which a species was reported for the monument. Species taxonomy follows the 4th edition of A Utah Flora (Welsh et al., 2008).
