Plants Belonging To Equisetum
Equisetum is a genus of vascular plants that reproduce by spores rather than seeds. The genus includes 15 species commonly known as horsetails and scouring rushes. These compose the entire class Equisetopsida, the sole member of the division Equisetophyta (Arthrophyta in older works), though some recent molecular analyses place the genus within the ferns (Pteridophyta), related to Marattiales. Other classes and orders of Equisetopsida are known from the fossil record, where they were important members of the world flora during the Carboniferous period.
