Equisetum sylvaticum
A portion of the fertile stem of Equisetum sylvaticum showing the leaf sheath and sheath teeth (leaves) which are papery, brown, and flare out from the top. Also visible is an emerging whorl of branches. The fertile stem with its branches will persist after the spores are shed, unlike the fertile stem of Equisetum arvense which withers after the spores are shed.
Habitat: along the edge of an alder thicket growing in peat moss.
