soon, however, lose their germinating power,, and should, 

 therefore, be sent home without much delay. 



1. Xepexthes albo-margixata, LiudL, a native of Singa- 

 pore and Sumatra, is a free-growing species, with peculiar 

 rigid leaves, which are covered with a white tomentum. 

 The pitcher is about 6 inches long, beautifully marked with 

 purple spots, and has a peculiar and characteristic white 

 band running round the neck of the pitcher. 



2. X. AMPULLARIA, Jack,* from Singapore and Bintang, is 

 a strong-growing species, which, when kept well in check, 

 produces more pitchers than any other kind. The pitchers 

 are small, 1 to 2 inches in length, having a deeply inverted 

 rim. The lid projects backwards from the mouth of the 

 pitcher, which is also distinguished by the absence of a con- 

 ducting surface. The presence or absence of the conducting 

 surface, and its relative length in the former case, is a 

 character of sufficient constancy in the different species to 

 afford a useful diagnostic mark. 



X. ampidlaria, var. vittata, and its form major, have 

 highly coloured pitchers. 



3. N. ANGUSTIFOLIA, Mast., from Sarawak, is a small green 

 pitchered species resembling the form grown as X. Icevis. 



4. X. BICALCAEATA is a native of Borneo and Sarawak ; 

 it is a very strong-growing species, ha\-ing a stem an inch 

 or more in thickness, and leathery leaves, each 2 to 3 feet long 

 and 4 to 5 inches broad, produced into a long rigid tendril- 

 like mid-rib, terminating in a stout bag-shaped pitcher. The 

 rim of the pitcher is peculiar in ha\'ing two sharp spurs 

 developed fiom it which point towards the mouth of the 

 pitcher. This species was first sent home alive by ^Mr. F. \\ . 

 Burbidge to Messrs Yeitch & Sons in 1879. 



5. X. cixcTA, Mast.,t endemic in Borneo, was raised from 

 seed collected by Mr Burke for Messrs Yeitch, and is supposed 

 to be a natural hybrid between X. Xorthiana and X. albo- 

 marginata. In cultivation it glows fi-eely and produces 

 extremely handsome pitchers about 7 inches in length, dark 

 green with irregular purple blotches. The mouth of the 

 pitcher is wide and the rim is finely ribbed, and has projecting 

 lobes, somewhat resembling those in the pitchers of X.
