Equisetum arvense L., [EQUAR]

General Description: Perennial. Never has flowers or seeds but reproduces by spores and by horizontal underground stems (rhizomes). Distinguished by its ashy-gray, unbranched, leafless shoots tipped with brownish, spore-producing cones in early spring, and later, from late spring or early summer onwards, by its whorls of 6 to 8 green, leafless branches and complete absence of flowers.
