Hawthorn \Haw"thorn`\ (h[add]"th[^o]rn`), n. [AS.
   haga[thorn]orn, h[ae]g[thorn]orn. See {Haw} a hedge, and
   {Thorn}.] (Bot.)
   A thorny shrub or tree (the {Crat[ae]gus oxyacantha}), having
   deeply lobed, shining leaves, small, roselike, fragrant
   flowers, and a fruit called {haw}. It is much used in Europe
   for hedges, and for standards in gardens. The American

   little lobed.
   [1913 Webster]

         Gives not the hawthorn bush a sweeter shade
         To shepherds?                            --Shak.
