Temporal range: Triassic to Bathonian
Sizes ranged from one to two meters tall and the leaves were arranged concentrically around a thin rod, similar to Annularia or Asterophyllites. Calamite is the name originally given to a part of the stem, but is now used to refer to the whole plant. There are indications that this plant lived in humid places along rivers and shores of lakes.
