Cusickiella is a small genus containing two species of plants in the family Brassicaceae which are native to the western United States.[1] These are mat-forming perennials with a stumpy, branching caudex covered in rounded clusters of tiny, thick leaves. A short stem bears white or yellowish flowers that yield silicles.[1]

The alkali cusickiella,[2] Cusickiella douglasii, grows in the hills and mountains from California to Washington, Idaho, and Utah.[1] It has white flowers and usually larger leaves, up to 14 millimeters long.[3]

The Bodie Hills cusickiella, Cusickiella quadricostata, has a more limited distribution in eastern California and western Nevada.[4] It can be distinguished from its congener by its yellow flowers, leaves no more than 5 millimeters long, and a keel along the valves on the silicle.[3]
