Brickellia greenei is a species of flowering plant in the daisy family known by the common name Greene's brickellbush. It is native to the mountain ranges of southwestern Oregon and northern California, including the Cascades, the northern Coast Ranges, and Sierra Nevada (mostly as north of Alpine County but with a few isolated populations in Inyo and Mariposa Counties). The species is named for American botanist Edward Lee Greene, 1843-1915.
