Annularia is an extinct plant that lived during a large part of the Carboniferous period (360 to 300 million years ago) The name Annularia is a form taxon, that is a name given on the basis of morphology, which in the case of Annularia is the radiating structure the leaves are set in. It is a large genus of pteridophytic plants of the order Equisetales. They much resemble the leaves of Calamites and their stems were also Calamites-like. The individual leaves in this variety are rounded, other Annularia have more pointed leaves. Provenance is Upper Carboniferous deposits near Piesberg, Germany. Actual width of sample is 130 mm
