Braun's horsetail
Equisetum braunii Milde

Equisetum braunii, known as Braun's horsetail or northern giant horsetail, is a species of the genus Equisetum in the family Equisetaceae. It is native to western North America, occurring in regions such as southeastern Alaska, western British Columbia, and extending south to California, including inland areas like Idaho. It was previously considered a subspecies of Equisetum telmateia, a European species, and is still classified as such by some authorities. The name 'giant horsetail' is sometimes used for this species, though it may also refer to other species like Equisetum giganteum and Equisetum myriochaetum.
