equiseta - Collaborative International Dictionary of English v.0.48 :

  Equisetum \Eq`ui*se"tum\, n.; pl. Equiseta. [L., the
     horsetail, fr. equus horse + seta a thick,, stiff hair,
     bristle.] (Bot.)
     A genus of vascular, cryptogamic, herbaceous plants; -- also
     called horsetails.
     [1913 Webster]
  
     Note: The Equiseta have hollow jointed stems and no true
           leaves. The cuticle often contains siliceous granules,
           so that one species (E. hyemale) is used for scouring
           and polishing, under the name of Dutch rush or
           scouring rush.
           [1913 Webster]
