Erigeron aequifolius is a rare species of flowering plant in the family Asteraceae known by the common names Hall's daisy and Hall's fleabane.[1]
Distribution
It is endemic to California , where it is known from fewer than 20 locations in the southern High Sierra Nevada of Mariposa, Fresno, Kern, and Tulare Counties. It grows in woodlands and coniferous forests.[1][2]
Description
Erigeron aequifolius is a small perennial herb growing a hairy, glandular stem up to about 20 centimeters (8 inches) tall from a woody caudex and taproot. The small leaves are equal in size and evenly spaced along the stem. The inflorescence is a usually solitary flower head at the tip of the stem. The head contains many yellow disc florets surrounded by a fringe of ray florets which are white when new and turn blue as they dry. The fruit is a tiny achene with a pappus of bristles.[3][4]
