| Erigeron saxatilis | |
Erigeron saxatilis is a rare North American species of flowering plant in the family Asteraceae known by the common name rock fleabane.[1] It has been found only in northern Arizona, in Yavapai and Coconino Counties north of the Mogollon Rim.[1][2]
Erigeron saxatilis grows on ledges and cracks in the walls of canyons. It is a very small perennial herb rarely more than 5 cm (2 inches) tall, forming a woody underground caudex. The inflorescence generally contains only 1 flower head per stem. Each head contains 20–29 white ray florets surrounding many yellow disc florets.[1][3]
