Nepenthes. 



§ I. Ascidia magna, ore lamellis latis disciformibus annularibus remotis instructo. 



1. Nepenthes villosa, H. f. (Hook. Ic. PI. t. 888). Ascidia magna turgida late pyri- 



forniia coiiacea 5" longa 3J" lata, alis anticis mediocribus grosse dentatis, ore aperto 

 auuulo maximo ! lamellis annvdaribus distautibus disciformibus rigidis 1" diam., 

 cristatis posticis in spinas rigidas -j" longas fundiim ascidii spectantibus productis, 

 coUo elongate erecto, operculo orbiculato intus densissime glanduloso dorso basi 

 longe cornuto. (Tab. LXIX.) 



Hab. Borneo [Lobb). Kini Balou, alt. 8000-9000 feet [Low). 



Tbis most remarkable pitcber resembles that of -A^. Edicardsimia in so many respects, 



especially in the size, form, and disposition of the distant lamellae of the mouth, that I am 



inclined to suspect that it may be produced by young plants of that species, before it 



arrives at a stage when the pitchers have elongated necks. 



The whole inner surface of the pitcher is glandular, except a very narrow area beneath 



the mouth at the back. 



2. Nepenthes Ebwabdsiana, Low, MSS. Foliis (6'' longis) crasse coriaceis longe petio- 



latis ellipticis, ascidiis magnis crasse pedunculatis cylindraceis basi ventricosis 8-18" 

 longis, ore lamellis annulariljus distantibus rigidis magnis cristate, collo elongate 

 erecto, operculo cordato-rotundato, racemo simplici, rachi pedicellisque ferrugineo- 

 tomentosis. (Tab. LXX.) 

 Hah. Kina Balou, north side, alt. 6000-8000 feet [Low). 



Mr. Low desires that this magnificent plant should bear the name of the Honourable 

 George Edwardes, Governor of Labuan, who has materially assisted him in his expeditions. 

 Under N. villosa, I have stated my suspicions that this may be the more mature form of 

 that plant with elongated pitchers. The leaves, ascidia, and pitchers sent by Mr. Low 

 are all old, and nearly glabrous ; but the young parts — rachis, peduncles of the panicle, 

 and the calyx — are covered with ferruginous tomentum. One of the pitchers sent is 

 18 inches long from the base to the apex of the erect operculum ; it is 2\ inches in dia- 

 meter below the mouth, 1^ at the narrowest part (about one-third distant from the base), 

 and the swollen part above the base is about 2 inches in diameter. The beautiful annular 

 discs which surround the mouth are f inch in diameter. 



§ II. Ascidia magna, curva, basi influta, medio conslricta, dein ampliuta, infundibuliformia ; ore maximo, 



lutissimo, annulo 0. 



3. Nepenthes Lowii, H. f. Caule robusto tereti, foliis crasse coriaceis longe crasse petio- 



latis lineari-oblongis, ascidiis magnis curvis basi ventricosis medio valde constrictis, 

 ore maximo ampUato, annulo 0, operculo oblongo intus dense longe setoso. (Tab. 

 LXXI.) 



Hab. Kina Balou, alt. 6000-8000 feet (Loio). 



A noble species with very remarkable pitchers, quite imlike those of any other species. 



They are cm-ved, 4-10 iuches long, swollen at the base, then much constricted, and suddenly
