Erigeron calvus is a very rare species of flowering plants in the daisy family known by the common names bald daisy or bald fleabane.[1] It has been found only once, in a collection made in 1891 at the western foot of the Inyo Mountains near the community of Swansea in Inyo County.[2][3][1]
The species is listed as "seriously endangered" and may quite possibly be extinct.[4]
Erigeron calvus is a small biennial or perennial herb about 12 cm (5 inches) tall, producing a taproot. One plant can produce several flower heads, sometimes one per branch, sometimes in groups of 2 or 3. Each head has 50-100 small ray florets that are small and resemble disc florets, plus numerous genuine disc florets.[3][2]
