Prehistoric Dwarf Horsetail Rush Plant – Equisetum
Equisetum scirpoides :Family: Equisetaceae (horsetail family):Common Names: Dwarf Horsetail Rush ::Description:Horstail rush is a spreading, reed-like perennial to 6 inches tall. The evergreen stems are cylindrical, jointed, hollow, usually unbranched, and have rough longitudinal ridges. The tiny leaves are joined together around the stem, forming a narrow black-green band or sheath at each joint. Like other Pteridophytes (ferns and their relatives), scouring rush does not produce flowers or seeds. Instead it develops a brown, cone-shaped, spore-producing strobilus at the tip of fertile stems, which are shorter than the infertile stems. The spores themselves are microscopic. ::Location:There are about 25 species of horsetails or scouring rushes occurring throughout the world except in Australasia. Common Horstail rush occurs in wet places, including pond margins, swamps, floodplains and ditches, in Eurasia and North America. It sometimes forms dense stands along bogs or marshes in northern US and Europe.
