Erigeron vicinus

Erigeron vicinus is a North American species of flowering plant in the daisy family known by the common names neighbor fleabane[1] and border fleabane.[2] It grows in north-central Mexico (state of Coahuila) and in western Texas in the United States. Some of the populations lie inside Big Bend National Park.[3][4]

Erigeron vicinus grows on rocky slopes and in canyons. It is a perennial herb rarely up to 30 centimeters (12 inches) tall, producing a taproot and a branching woody caudex. It generally produces 1-2 flower heads per stem. Each head contains 60–95 ray florets, each ray white with a lilac stripe along the middle/ The rays surround numerous yellow disc florets.[1][5]

The species was named vicinus, meaning "neighbor",[6] in reference to the close proximity of the international border to the location where the plant was first collected.[5]
