THE MOVEMENTS AND HABITS OF PLANTS. 39 



perish either within the neck or ntricle ; and the qnadrifid 

 and bifid papillae would absorb matter from their decayed 

 remains. The transverse rows of hairs are so nnmerons 

 that they seem superfluous merely for the sake of pre- 

 venting the escape of prey, and, as they are thin and 

 delicate, they probably serve as additional absorbents, in 

 the same manner as the flexible bristles on the infolded 

 margins of the leaves of aldrovanda. The spiral arms, 

 no doubt, act as accessory traps. Until fresh leaves are 

 examined, it can not be told whether the line of junc- 

 tion of the spirally-wound lamina is a little open along 

 its whole course or only in parts, but a small creat- 

 ure which forced its way into the tube at any point 

 would be prevented from escaping by the incurved hairs, 

 and would find an open path down the tube into the 

 neck, and so into the utricle. If the creature perished 

 within the spiral arms, its decaying remains would be ab- 

 sorbed and utilized by the bifid papilla;. We thus see 

 that animals are captured by genlisea, not by means of 

 an elastic valve, as with the foregoing species, but by a 

 contrivance resembling an eel-trap, though more complex.
