It has been found only in a few locations in Mariposa County in California.[2] Some sources say that it is now probably extinct.[1][2]Erigeron mariposanus is a perennial herb up to 28 centimeters (11 inches) tall, producing a woody taproot. The leaves and the stem are covered with hairs. The plant generally produces 1-4 flower heads per stem, each head with up to 22 blue ray florets surrounding numerous yellow disc florets.[3] References1. ^1 Calfora taxon report, University of California, Erigeron mariposanus Congdon, Mariposa daisy {{Taxonbar|from=Q15602005}}{{Astereae-stub}}2. ^Biota of North America Program 2014 county distribution map 3. ^1 Flora of North America, Erigeron mariposanus Congdon, Erythea. 7: 185. 1900.
