Erigeron ursinus is a North American species of flowering plant in the family Asteraceae known by the common name Bear River fleabane.[2] It is native to the western United States, from Montana and Idaho south as far as Arizona and New Mexico.[3]
Erigeron ursinus grows in sunny locations in sagebrush and in open coniferous woodlands. It is a small perennial herb rarely more than 8 centimeters (3.2 inches) tall, producing rhizomes and a branching underground caudex. The inflorescence is made up of only one flower heads per stem. Each head contains 14–30 white, pink, or purple ray florets surrounding numerous yellow disc florets.[2]
