Calamites is an extinct genus of tree-like horsetails from the Carboniferous coal swamps, related to the modern Equisetum. It cannot be grown today, as it is known only from fossils.
Calamites is a genus of extinct arborescent (tree-like) horsetails to which the modern horsetails (genus Equisetum) are closely related. Unlike their herbaceous modern cousins, these plants were medium-sized trees, growing to heights of 30–50 meters (98–164 ft). They were components of the understories of coal swamps of the Carboniferous Period (around 360 to 300 million years ago).
