366 Descriptions of Malayan Plants. 



Obs. — This is the largest and most magnificent species of 

 the genus, being adorned with two kinds of urns, both ele- 

 gant in their forms, and brilliant in their colouring. It was 

 first discovered with the following species in the forests of 

 Singapore by Sir T. Stamford Raffles, Lieut.-Governor of 

 Sumatra, when he established a British Colony on that is- 

 land, in February, 1819. To him, therefore, it is justly dedi- 

 cated. 



NEPENTHES AMPULLARIA. (W. J.) 

 Caule basi repente surculos urniferos promente demum 

 erecto foliifero, cirrhis foliorum muticis, ascidiis petiolatis 

 confertis inflatis antice membranaceo-alatis, ore coarctato 

 subrotundo striato, operculo lanceolato reflexo postice tricus- 

 pide. 



Found along with the preceding in the forests of Singapore, 

 also at Rhio, on the island of Bintang. Malacca, W. G. 



Root fibrous. Stem repent at the base, becoming erect, 

 and supporting itself on the neighbouring trees, round, co- 

 vered with a deciduous ferruginous down, urn-bearing at the 

 base, and leaf-bearing above. The urn-bearing shoots or 

 suckers are short and spring from, the repent part of the 

 stem ; they are entirely sheathed by the crowded petioles of 

 the urns, which are dilated and amplexicaul at the base. 

 The urns or ascidia are supported on short straight petioles ; 

 they are erect, ovate, inflated, green and spotted with purple, 

 furnished anteriorly with two longitudinal, membranaceous, 

 fimbriated wings ; mouth somewhat contracted, striated, of a 

 uniform yellowish green colour, and nearly round, the in- 

 verted margin being prolonged further into the interior of 

 the cup than in the other species. The Operculum is lan- 

 ceolate-oblong, generally reflexed, tricuspid behind the 

 hinge. It opens at an early stage, and as the urn enlarges, 

 it becomes much too small to reclose it. The leaves come 

 on the erect part of the stem, and are alternate, subpetiolate.
