Cosmos \Cos"mos\, n. (Bot.)
   A genus of composite plants closely related to {Bidens},
   usually with very showy flowers, some with yellow, others
   with red, scarlet, purple, white, or lilac rays. They are
   natives of the warmer parts of America, and many species are

   among the best-known species; {C. caudatus}, of the West
   Indies, is widely naturalized.
