Calamites Living Desendants

This plant is known as Equisetum or common names Horsetail reed or pewterwart. It is known as a living fossil. The plant is a descendant of Calamites.

This post on Neocalamites fossil plants at Malaysian Triassic Blog inspired me to create today's entry. I had been meaning to post these recently taken pictures.

These first three pictures were taken recently in Washington state.

These last four were taken in Paris, France near the Jardin Des Plantes.
