Insects are caught in another way, and more expertly, by the most extraordinary of all the plants of this country, the Dionsea or Venus's Fly- trap, which grows in the sandy bogs around Wilmington, North Carolina. Here (Fig. 170) each leaf bears at its summit an appen- dage which opens and shuts, in shape some- thing like a steel-trap, and operating much like one. For when open, no sooner does a fly alight on its surface, and brush against any one of the two or three bristles that grow there, tlian the trap suddenly closes, captur- ing the intruder. If the fly escapes, the trap soon slowly opens, and is ready for another oa]>lure. When retained, the insect is after a time moistened by a secretion from mi- imte glands of the inner surface, and is digesteil. In the various species of Drosera or Sundew, insects are caught Fig. 174. Leaf of Sarracenia purpurea, entire, and another with the upper part cut off. Fig. 175. Leaf of Nepenthes; foliage, tendril, and pitcher combined. Fig 176. Leaves of Diousea; the trap in one of them open, in the others closed. 5.
