President's Address. 235 



1878 to Messrs Veitch & Sons. Unfortunately, it has not 

 proved very amenable to culture, but it is to be hoped that 

 some one may find out its requirements, and succeed in grow- 

 ing it so as to produce those marvellous virus. Notwithstand- 

 ing every care, our Edinburgh plant perished. 



17. K SANGUINEA, Lindl., a native of Malacca, is a rare 

 and extremely handsome species having large crimson 

 coloured pitchers. It grows freely enough, but is rather 

 difficult to increase by cuttings. 



18. X. Yeitchii, Hook, fil.,* grows in Borneo, at an 

 altitude of from 1000 to 3000 feet. It is a remarkable 

 species, having a peculiarly low spreading manner of growth, 

 not upright like most of the species. The whole plant is 

 densely covered with brown hairs. The pitchers are from 6 

 to 12 inches in length and yellowish-green in colour. The 

 mouth is surrounded by a very broad everted margin of a 

 light golden colour. The conducting surface is very small, 

 covering scarcely an inch of the length of the back of the 

 pitcher. 



These are all the species at present in cultivation in the 

 Eoyal Botanic Garden, Edinburgh. So far as I am aware, 

 the only others in cultivation are N. madagascariensis, Poir, 

 and K Burkei. The latter, described by Dr Masters, t was 

 introduced by Messrs Veitch & Son from the Philippine 

 Islands, and named after their collector, Mr Burke.
