A genus of spore-bearing plants commonly called horsetails, characterized by jointed hollow stems with whorled branches or leaves.
From Latin 'equus' (horse) + 'seta' (bristle), literally 'horse-tail.' The name describes the plant's bushy, feathery appearance resembling a horse's tail.
Horsetails (equisetum) are the last survivors of plants that once dominated Earth 300 million years ago—some of their ancient relatives grew as tall as trees and formed most of our coal deposits!
