    		Action: changed name from "Equisetum laevigatum" to "Equisetum arvense "

    		Reviewer's comments:
         "This I'm less sure about--maybe mutant arvense? Appears to have fertile cones on nongreen stem with green "leaves" or branches as a sterile stem should look? Pic not clear enough to say for sure."
