Rajfflesiana, with which it agrees iii size and colour only, 

 while it differs so much in other features that I am inclined 

 to regard it as a natural hybrid between N. ampullaria and 

 N. Rajflesiana. 1 hope to have an opportunity some day by 

 crossing these two species of ascertaining w^hether this 

 conjecture is coiTect or not. 



N. Hookeriana elongata is a variety, which we have in 

 cultivation in Edinburgh, differing slightly in habit and in 

 shape of pitcher from the type. 



10. N. Kennedy AX A, F. Mueller, a native of York 

 Peninsula, Australia, comes very near to N. PhyllamiDlwra, 

 but does not gi-ow so freely as that species. The pitchers 

 differ in being slightly tinged with red, and have less 

 conducting surface. 



11. K KHASIANA is found in Eastern Bengal at 3000 

 feet altitude. This, the N. distillatoria of gardens, and as 

 such figured in the ' Botanical Magazine,' is one of the best 

 known in cultivation. It has narrow funnel-shaped 

 pitchers, 8 to 10 inches long when fully developed. The 

 conducting surface extends to about half the length of the 

 pitcher, and has a purplish glaucous appearance. Xearly 

 every pitcher is supported by a tendril, and the lamina of 

 the leaf has a flaccid appearance. One of the oldest in 

 cultivation, it is still one of the most ornamental species. 



12. N. LiEVis resembles N. gracilis, but differs in having 

 narrower leaves. The rim and the wings of the pitchers 

 are not so well developed as in N. gracilis. 



13. N. NoRTHiANA, Hook, fil., a native of Sarawak, altitude 

 1000 feet, is one of the largest and most magnificent of 

 all the species. It was discovered by Miss Xorth, whose 

 drawing of the plant induced Mr Veitch to send out a 

 collector, Mr Curtis, to search for it, and he succeeded in 

 introducing it in 1881. When fully developed, the pitchers 

 are 16 inches in length by 5 inches wide. The plant 

 seems to be quite easily cultivated, and I have no doubt 

 that in course of time these large mature pitchers will 

 also be produced by cultivated plants. Our plant in Edin- 

 burgh (which is a young one) has pitchers 4i inches long 

 by 2 inches wide, and they are larger in size on every leaf 

 that is made. The pitcher is peculiar in being highly 

 coloured inside, and in having only faint blotches of purple
