Discussion
Antennaria arcuata is known from three widely disjunct areas in Blaine County, Idaho; Elko County, Nevada; and Fremont County, Wyoming (R. J. Bayer 1992). It is characterized by arching stolons and white-woolly indument (Bayer) and is not easily confused with other species of Antennaria.
Selected References
None.
