Devil's club or devil's walking stick (Oplopanax horridus, Araliaceae; syn. Echinopanax horridus, Fatsia horrida) is a large understory shrub endemic to the arboreal rainforests of the pacific northwest, but also disjunct on islands in Lake Superior. It is noted for its large palmate leaves and erect, woody stems covered in noxious and irritating spines. It is also known as Alaskan ginseng and similar names, although it is not a true ginseng.
