equisetum

Mike's Head is probably a popular name for the rush of the Equisetum species, known as "horsetail."

In this connection his figuring young plants of Equisetum attached to prothalli is interesting.

The swampy regions by the rivers are covered with Equisetum and Scirpus cspitosus; and they are very abundant on the mountains.

To take away the unevennesses and roughnesses dried shave-grass (equisetum) answers best.

In the more damp and marshy places the bottom is covered with marsh trefoil, carex, smooth equisetum, and rush.
