ties into filiform flexible cords, more or less spirally 

 twisted. 



(80.) Pitcher. Of all the metamorphoses which 

 the leaf is found to undergo, the singular productions 

 called " pitchers" are the most curious. The annexed 



cut (fig. 71-) represents three different forms of these 

 organs. 



(a.) In the genus Sarracenia, nearly the whole leaf 

 resembles a funnel, with the upper extremity crowned 

 by a membranous expansion, tapering to a point. 



(6.) In the Nepenthes, or true pitcher-plant, the 

 pitcher (6) is placed at the extremity of a tendril, ter- 

 minating a winged petiole. It is crowned with a mem- 

 branous lid, which is closely shut in the early stages of 

 its growth, but is afterwards raised, and does not again 

 close the aperture. These pitchers, in some species, 

 are six or seven inches in length, and have the lower 

 portion of the inner surface, of a glandular structure, 

 which is constantly secreting a subacid liquid. In 

 this liquid a number of insects are continually drowned ;
