List of vascular plant taxa:
Total of 291 taxa listed here (there are more to be added - see rare plant master list).
Plants occurring in Utah with a formal federal status as of 6/24/20:
25 listed (12 LT, 13 LE)
2 candidates (C) (candidate count increased from 3 to 5 on 10/25/16 due to a Colorado court decision then less 3 on 12/19/18)
For an explanation of NatureServe rankings including G-ranks and S-ranks, see NatureServe Conservation Status Assessment
ESA status codes: LE=listed as endangered; LT=listed as threatened; C=Candidate species; PE=Proposed Endangered; PT=Proposed Threated; EM=Emergency listing package submitted; NOR=Notice of review
See bottom of this page for a brief discussion of taxa formally federally listed from Utah.
NOTE: please refer also to the latest UNPS Rare Plant Committee lists published in Calochortiana, the UNPS botanical research journal, for the most current information.
Taxa as ranked by the UNPS Rare Plant Committee since 2009:
Year exH High Total

Cirsium virginense
C. virginense has been lumped with C. mohavense in the Flora of North America (vol 19, pg 134), and the distinction between perennial (C. virginense) and biennial (C. mohavense) may not be valid. Even if recognized as C. mohavense it would remain rare in Utah at the periphery of its range here, and since C. mohavense is a globally rare species. Might be properly recognized at varietal level.

Cronquist (1997) in Intermountain Flora Vol. 3A included C. acaulis var. higginsii under C. acaulis var. fendleri. Sun et al (2005) in Rhodora determined that C. acaulis was nomenclaturally invalid placing it in Cymopterus glomeratus but without distinguishing any varieties. This leaves the above entity currently in taxonomic limbo.

Taxa formerly federally listed in Utah
Astragalus perianus: listed as threatened effective 5/27/78, delisted eff. 10/16/89, more information (species was listed prematurely prior to being fully surveyed, the indication that it "recovered" by FWS is not accurate; still considered rare and is therefore contained in the list of globally rare plants above; the first ever plant species to be delisted under the Endangered Species Act and for reasons unrelated to taxonomy, delisting action was initiated by Dr. Duane Atwood then of the USFS)
Astragalus desereticus: listed as threatened Oct. 20, 1999, delisted via rule published Oct. 18, 2018, delisting effective Nov. 19, 2018, more information
Echinocereus engelmanii var. purpureus: listed as endangered 10/11/79, delisted eff. 12/27/89, more information (no longer considered a valid taxon, however, there remains a purple-spined form of Echinocereus engelmanii that warrants conservation attention)
Echinocereus triglochidiatus* var. inermis: listed as endangered eff. 12/7/79, delisted eff. 9/22/93, more information (while no longer considered a valid taxon, this mostly spineless form of what is actually Echinocereus mojavensis* still warrants and receives management attention; *as now understood and unrelated to prior disposition of the "inermis" variety, the species Echinocereus triglochidiatus does not occur in Utah)
Erigeron maguirei: listed as endangered effective 10/7/85 (FR 9/5/85), reclassified to threatened effective 7/19/96 (FR 6/19/96), delisted eff. 2/18/11, more information
