Packera macounii is a species of flowering plant in the aster family known by the common name Siskiyou Mountains ragwort.[1][2] It is native to the west coast of North America from British Columbia to far northern California, where it grows in chaparral and mountain forests, often on serpentine soils.
It is a perennial herb producing a single erect stem up to 40 or 50 centimeters in maximum height from a taproot and branching caudex unit. It is slightly hairy to quite woolly in texture. The leaves have lance-shaped blades several centimeters long which are borne on long petioles. The inflorescence holds several flower heads containing many disc florets and usually either 8 or 13 yellow ray florets each about a centimeter long.
