closing it except in the young state. The pitcher developes by an in- 

 vagination of the upper surface of the tip of the 1. ; the tip takes no 

 part in the development, and the lid grows out below it. The edge 

 of the pitcher is curved inwards; at the entrance are numerous honey- 

 glands, and for some distance below it are other glands, sunk in little 

 pits on the inner surface. Insects attracted by the honey (or by the 

 bright colour) gradually work their way downwards among the glands, 

 and presently get upon the slippery lower part and ultimately into the 

 water at the bottom of the pitcher, where they are drowned. The 

 plant absorbs the products of their decay. 



Many are epiphytic. In N. ampullaria Jack there are two kinds 

 of 1. (cf. Cephalotus), some with tendrils and no pitchers; others, as 

 stalked pitchers arranged in a radical rosette.
