Eurybia wasatchensis is a perennial herb up to 60 centimeters (2 feet) tall from a woody underground caudex. The plant produces flower heads in groups of 2-20 or more heads. Each head contains 13–21 white or pink ray florets surrounding 26–43 yellow disc florets.[2]
Taxonomy
editEurybia wasatchensis was first described and named as a subspecies, Aster glaucus var. wasatchensis, by Marcus E. Jones in 1895.[1] Further study by the famous botanist Per Axel Rydberg lead to him publish a book where it was classified as a species with the name Eucephalus wasatchensis in 1917. Eight years later Sidney Fay Blake wrote in favor of its inclusion in the large Aster genus.[1] In 2004 Luc Brouillet published a paper arguing for its being renamed Herrickia horrida along with a general reorganization of three other species into a restored genus, Herrickia.[3] This is the classification used in the Flora of North America.[4] However, as of 2023 Plants of the World Online (POWO) and the USDA Natural Resources Conservation Service PLANTS database (PLANTS) accept the 1995 description by Guy L. Nesom as Eurybia wasatchensis.[5][1][6]
Range
editThough it has sometimes been reported from the state of Arizona, POWO and PLANTS both report it is endemic to the state of Utah.[7][1][6]
