Macfarlane, .in the ' Monograph of Nepenthes,' says this is 

 allied. Endemic. 



*i43. Nepenthes Singalana, var. alba. 

 Nepenthes Bongso, Ridl. op. cit. p. 320. 



In the previous paper I referred this plant to N . Bongso, 

 Korthals, but Macfarlane in the Monograph published in the 

 ' Pflanzenreich ' refers it to N. Singalana, Becc, of Singalang 

 Mountain in Sumatra. Beccari figures a pitcher of this plant 

 of very much greater size than anj' I have seen of the plant on 

 the Tahan Padang, and though he does not appear to have 

 recorded the colour of the pitchers at the time of gathering he 

 gives them as dark purple. The plant is extremely common 

 all over the Padang in the driest and rockiest spots, having 

 a short thick stem deeply imbedded in cracks in the rocks, 

 from which numerous long stems are emitted, which scramble 

 over bushes and often form a very large mass. The pitchers 

 are always very small, about the size of those of N. gracilis, 

 and, on the whole, rather larger than those of A^ gracillima. 

 Usually they are of an ivory-white colour tinted with green at 

 the base, and before opening of a yellow tint, and Mr. Kloss 

 brought in one of a pure canary-yellow. The lid and the 

 upper part of the pitcher within are frequently spotted with 

 circular spots of pure rose-colour, and as the pitcher begins to 

 wither it develops irregular blotches of the iTsual dull red 

 of the other Nepenthes. This colouring is, I think, quite unique 

 in the order of Nepenthaceae. The pitchers usually contained 

 little or no water, being quite dry inside. I found in the 

 liquid, where there was any, the remains of ants and small 

 diptera, and on one occasion a small Rutelid beetle, which 

 was alive and uninjured, but most of the pitchers contained 

 nothing. 



BALANOPHORACE^. 



144. Balanophora multibrachiata, Fawc. Common 

 in the Padang woods up to 6,000 feet, deeply buried in the 

 ground and just coming into flower. This species is common 

 at high altitudes all over the Peninsula. 



PIPERACE^. 



145. Piper sp., near P. stylosnm, Miq. In the Gully in 

 wet spots. This may be a variety only of P. stylosnm, but it is 

 certainly not typical, and I have no specimens quite like it in 

 the herbarium, except a similar plant collected on Gunong 

 Kerbau by Mohamed Aniff. 



146. Piper gymnocladum, De Cand., var. This grew 

 with the last species in the Gully. It differs from the plant 

 which is a native of the Taiping hills, and is named by De 

 Candolle P. gymnocladum, in. its more coriaceous leaves, and 

 may be a distinct species. The Piperaceae of the materials for 

 ' A Flora of the Malay Peninsula ' are not yet published.*
