Abstract: In 2005–2006, the National Park Service’s Northern Colorado Plateau Network received funding to develop a revised checklist of the vascular plant flora of Capitol Reef National Park. This entailed a thorough review of existing literature, re-examination of specimens from the Capitol Reef National Park herbarium and other state and national museum collections, and additional field work to corroborate unverified species reports or locate new species. Based on this study, 887 vascular plant taxa have been confirmed or reliably reported as occurring in the park (835 are known from validated herbarium specimens and 52 from unvouchered literature reports). Another 117 species formerly considered part of the park flora have now been shown to be falsely reported. The current flora of Capitol Reef National Park represents about 25% of the known flora of Utah, and 52.4% of the flora of the Colorado Plateau ecoregion within Utah. At least 7 of these species are federally listed as threatened or endangered, and 54 more are considered species of concern by the state natural heritage program. Introduced plants make up 13.8% of the park flora (45 species), of which only 3 species are considered noxious weeds by the State of Utah. Further surveys in Capitol Reef National Park are likely to find additional new species (about 192 are known from similar habitats outside the park boundary), especially among late- season flowering, weedy, or wetland taxa. This checklist includes updates from 2011-2012.
