   + t[=a]n twig. AS. mistel is akin of D., G., Dan. & Sw.

   (Bot.)
   A parasitic evergreen plant of Europe (Viscum album), bearing
   a glutinous fruit. When found upon the oak, where it is rare,

   Note: The mistletoe of the United States is {Phoradendron

         kind. In different regions various similar plants are
         called by this name.
