Numéro d’image : 11686637
| Equisetum,is the only living genus in the family of the Equisetaceae (class of Equisetopsida),vascular plants that reproduce by spores rather than seeds. They are popularly known as horsetails,snake grass or puzzle-grass. Equisetopsida were large trees that thrived in swampy areas and could grow as tall as 30 meters. They grew with whorls of needle-like branches radiating at regular intervals from a single,vertical stem that was segmented horizontally and vertically ribbed.Equisetum is a "living fossil" as it is the only living genus of the entire class of Equisetopsida,formerly widespread and much more diverse for over at least a hundred million years in the profuse forests of the later Palaeozoic era | |
