Equisetum praealtum
Also called Tall Scouring-Rush, River Scouring-Rush, Scouring Rush
Equisetum praealtum, the scouringrush horsetail, is a species of Equisetum (horsetail) native to North America and northeastern Asia. It was formerly widely treated as a subspecies or variety of the European and west Asian species Equisetum hyemale (rough horsetail), and still is by some authorities.
It is found in wet places, including roadside ditches, along rivers, lake shores, and in wet woods.
