Equisetum braunii, the northern giant horsetail, is a species of Equisetum (horsetail) native to western North America.[1] It was formerly widely treated as a subspecies of the European species Equisetum telmateia, and still is by some authorities.[2] It is often simply but ambiguously called "giant horsetail", but that name may just as well refer to the Latin American species Equisetum giganteum and Equisetum myriochaetum. The range extends from southeastern Alaska and western British Columbia south to California, mainly in coastal regions,[2] but also inland to Idaho.[1]
