the}' narrow off to the surface, the lower end being just at the 

 upper extremity of the lateral gland-mass of the interior. These 

 lateral wings are thin ribs, widest at the upper end, and standing 

 perpendicularly to the surface, but not extending laterally as the 

 front wing does; they also have a border of stiff hairs. 



As before said, the pitchers vary much in size when full grown. 

 The largest, which I saw in our first search, I did not collect, or 

 measure, but it was not less than 5-5 cm. long. The figure in 

 Curtis' Botanical Magazine shows very large pitchers. The 

 following are some measurements : — 



Length. Breadth. Diameter of Orifice. 



Front to Back. Side to Side. Front to Back. Transverse. 



No. 1. 4 cm. 2'35cm. 2*45 cm. 0-7cni. 1*3 cm. 



No. 2. 3-6 cm. 2*0 cm. 2-2 cm. O'll cm. l"3cm. 



No. 3, 3'25c.m. 1*7 cm. 2*2 cm. 0*7 cm. 1*2 cm. 



The coloration of the pitchers varies. Generally speaking, it 

 consists of irregular markings of red or purplish on a green 

 ground, and the general arrangement is similar to that in the 

 pitchers of NejientJies. The young pitchers are bright green. 

 The outer surface is smooth but not glossy. The interior varies 

 from green in very young pitchers, bright red in full grown 

 specimens, and a deep glossy black in old ones. This when 

 examined by transmitted light is a dark purplish-crimson. 

 Young specimens in spirit bleach almost white, while older ones 

 remain dark brown or blackish, the spirit becoming pink, which 

 afterwards changes to dull brown. The deep colour of the 

 interior, I think, depends on the amount of animal matter they 

 contain, and I should not be surprised to learn that the exterior 

 colouring has some relation to the same factor. This is a matter 

 in which observations on the plant in its native habitat are 

 required. When the pitchers are fading, the green parts turn 

 yellow and the purple bright red. 



The pitchers rest on the ground so that they slope forwards, 

 throwing the surface line of the contained fluid higher up at the 

 stalk end than in front, and it will be seen that this is related 

 to the distribution of the internal slands.
