Calamites is a genus of extinct arborescent (tree-like) horsetails to which the modern horsetails (genus Equisetum) are closely related.[1] Unlike their herbaceous modern cousins, these plants were medium-sized trees, growing to heights of 30–50 meters (100–160 feet).[2] They were components of the understories of coal swamps of the Carboniferous Period (around 360 to 300 million years ago).
