 a destroyer, though its greatest injury is done after 

 the leaf has performed its most important functions. 

 Almost every plant has its peculiar insect enem}', 

 and Sarracenia, with all its dangers to insect life 

 generally, is no exception to the rule." ^ 



Another plant,^ very similar to the Sarracenias, is 

 found at an elevation of 5,000 feet on the Sierra 

 Nevada of California. " It has pitchers of two forms ; 

 one, peculiar to the infant state of the plant, consists 

 of narrow, somewhat twisted trumpet-shaped tubes, 

 with very oblique open mouths, the dorsal lip of 

 which is drawn out into a long, slender, arching, 

 scarlet hood that hardly closes the mouth. The 

 slight twist in the tube causes these mouths to point

 insects onl}'. Before arriving at a state of maturit}- 

 the plant bears much larger, nearly erect pitchers, 

 also twisted, with the lip produced into a large in- 

 flated hood that completely arches over a very small 

 entrance to the cavity of the pitcher. A singular
