Erigeron sceptrifer is a North American species of flowering plant in the daisy family known by the common name Scepter-bearing fleabane..[1] It has been found in northern Mexico (Chihuahua, Sonora, San Luis Potosí) and the southeastern United States (Cochise County in Arizona).[1][2][3][4]
Erigeron sceptrifer grows in grasslands, frequently alongside widely spaced pine, oak, and juniper trees. It is an annual herb up to 80 cm (32 inches) tall, forming a thin taproot. The inflorescence generally contains 20–50 flower heads in a loose array. Each head can sometimes contain as many as 195 white ray florets surrounding many yellow disc florets.[1][5]
