Equisetales is an order of subclass Equisetidae with only one living family, Equisetaceae, containing the genus Equisetum (horsetails), as well as a variety of extinct groups, including the tree-like Calamitaceae.

Classification
editIn the molecular phylogenetic classification of Smith et al. in 2006, Equisetales, in its present circumscription, was held to be the sole member of class Equisetopsida.[1] The linear sequence of Christenhusz et al. (2011), intended for compatibility with the classification of Chase and Reveal (2009)[2] which placed all land plants in Equisetopsida,[3] made it the sole member of subclass Equisetidae, equivalent to Smith's Equisetopsida.[2] The placement of Equisetales in subclass Equisetidae has subsequently been followed in the classifications of Christenhusz and Chase (2014)[4] and PPG I (2016).[5]
The fossil record includes additional extinct species in Equisetaceae and the extinct families Calamitaceae, Archaeocalamitaceae and Phyllothecaceae.[6][7]
