It grows to 40 centimetres (16 inches) in height, its leaves 2.5–6.5 cm (1–2+1⁄2 in) long and white on the underside (hence the specific epithet, meaning 'bottom white').[2] It flowers between June and October, with yellowish rayless flower heads about 9 millimetres (3⁄8 in) long.[2] It is found in North America on open and usually rocky places between elevations of 70–2,100 metres (230–6,890 feet) in British Columbia, California, Oregon, and Washington.[3]
