About

Barkleyanthus is a monotypic genus of flowering plants in the aster family, Asteraceae, containing the single species Barkleyanthus salicifolius, a plant formerly classified in the genus Senecio. It is native to North and Central America, where its distribution extends from the southwestern United States to El Salvador. Its common names include willow ragwort, willow groundsel, Barkley's-ragwort, and jarilla.

This plant is a shrub producing a branching stem usually about one to two meters tall, but known to exceed 4 meters at times. The leaves are roughly lance-shaped and are alternately arranged, sometimes more densely toward the ends of branches. They are up to 10 or 15 centimeters long. The inflorescence is often a wide array of several flower heads, but they may also be clustered in the leaf axils or branch tips.
