Common throughout the region. It prefers to grow in water but is also found in marshes/swamps.
Equisetaceae is the only surviving family of the Equisetales, a group with many fossils of large tree-like plants that possessed ribbed stems similar to modern horsetails. The oldest known relative of Equisetum is from the late Devonian (ca. 375 million years ago).
These plants do not have flowers. The cone releases spores, which grow into gametophytes.
These gametophytes produce the sperm and eggs, which fuse and ultimately grow into a mature plant.
