Equisetum arvense, the field horsetail or common horsetail, is an herbaceous perennial plant in the Equisetidae (horsetails) sub-class, native throughout the arctic and temperate regions of the Northern Hemisphere. It has separate sterile non-reproductive and fertile spore-bearing stems growing from a perennial underground rhizomatous stem system.
Equisetum (/ ˌ ɛ k w ɪ ˈ s iː t əm /; horsetail) is the only living genus in Equisetaceae, a family of vascular plants that reproduce by spores rather than seeds. [2]Equisetum is a "living fossil", the only living genus of the entire subclass Equisetidae, which for over 100 million years was much more diverse and dominated the understorey of late Paleozoic forests.
The extant horsetails represent a tiny fraction of horsetail diversity in the past. There were three orders of the Equisetidae. The Pseudoborniales first appeared in the late Devonian. [1] The Sphenophyllales were a dominant member of the Carboniferous understory, and prospered until the mid and early Permian.
Grypus equiseti, known by the common name horsetail weevil, is a species of weevil native to Europe. [2] [3] [4] It feeds on Equisetum arvense (field horsetail or common horsetail) and Equisetum palustre (marsh horsetail) plants. [5] It has been introduced to New Zealand to control Equisetum arvense, which is an invasive species there.
Equisetaceae, also known as the horsetail family, [1] is a family of ferns and the only surviving family of the order Equisetales, with one surviving genus, Equisetum, comprising about twenty species.

Equisetum hyemale (rough horsetail [2]) is an evergreen perennial herbaceous pteridophyte in the horsetail family Equisetaceae native to Eurasia and Greenland. It was formerly widely treated in a broader sense including a subspecies (subsp. affine) in North America, but this is now treated as a separate species, Equisetum praealtum. [3] [4]
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 .
