Equisetum telmateia, the great horsetail, is a species of Equisetum (horsetail) native to Europe, western Asia and northwest Africa.[2][3] It was formerly widely treated in a broader sense including a subspecies (subsp. braunii) in western North America, but this is now treated as a separate species, Equisetum braunii.[4][5]
