Description

Sizes ranged from few centimetres to two meters tall and the free leaves occurred at the nodes of the aerial stems. It is supposed that they produced secondary tissues as Calamites, but had bractless cones similar to Equisetum.[1] There are indications that this plant lived in humid places along rivers and shores of lakes.
