This genus affords a strikinsr example of a creat modific.ition of the petiole, since 

 there is no doubt that the tube part is the petiole, and what we called the lamina, the 

 true lamina of the lejif These tubes are generally tiHed with water, wliith is sup- 

 po^^ed to l)e secreted by the plant, and this always contains dead insects. The tube 

 could not have been formed in a better manner to accomplish a given end, than this is 

 to catch insects. The .saccharine secretion which surrounds the orifice decoys insects 

 to the tube, and the water entices them in. There are hairs pointing downward, so as 

 to permit an easy descent, but makes the egress ditlicult.
