This tree, in size up to 20 meters, grew in the
coal-swamps of the Carboniferous, the period in
which most of the coal has been formed.
Originally the name Calamites was only given to the articulated and ribbed casts of the central pith of the trunk, but now the name is also used for the entire plant.
It has yielded many kinds of fossils.
