Sarracenia \Sar`ra*ce"ni*a\, prop. n. [NL. So named after a Dr.
   Sarrazin of Quebec.] (Bot.)
   A genus of American perennial herbs growing in bogs; the
   American pitcher plant.
   [1913 Webster]

   Note: They have hollow pitcher-shaped or tubular leaves, and
         solitary flowers with an umbrella-shaped style.
         Sarracenia purpurea, the sidesaddle flower, is common
         at the North; Sarracenia flava, Sarracenia rubra,
         Sarracenia Drummondii, Sarracenia variolaris, and
         Sarracenia psittacina are Southern species. All are
         insectivorous, catching and drowning insects in their
         curious leaves. See Illust. of Sidesaddle flower,
         under Sidesaddle.
