Horsetail Overview

Equisetum is a genus containing around 18 herbaceous perennials also known by the names Horsetail, Snake Grass and Puzzlegrass. They resemble reeds and consist of photosynthetic, green, hollow, unbranched, jointed and ridged stems with reduced, usually non-photosynthesising leaves. Species in this genus have not evolved notably since the Paleozoic Era, when they were at their most diverse and this is the only living genus in the class Equisetopsida, providing an example of a living fossil.
