420 DR. J. D. HOOKER ON THE BORNEAN SPECIES OF NEPENTHES. 
NEPENTHES. | 
$ I. Ascidia magna, ore lamellis latis disciformibus annularibus remotis instructo. 
1. NEPENTHES VILLOSA, H. f. (Hook. Ic. Pl. t. 888). Ascidia magna turgida late pyri- 
formia coriacea 5" longa 32” lata, alis anticis mediocribus grosse dentatis, ore aperto 
annulo maximo! lamellis annularibus distantibus disciformibus rigidis 1" diam, 
cristatis posticis in spinas rigidas 3" longas fundum ascidii spectantibus productis, 
collo elongato erecto, operculo orbiculato intus densissime glanduloso dorso basi 
longe cornuto. (Tas. LXIX.) 
Hab. Borneo (Lobb). Kini Balou, alt. 8000-9000 feet (Low). 
This most remarkable pitcher resembles that of N. Edwardsiana in so many respects, 
especially in the size, form, and disposition of the distant lamellze 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 EDWARDSIANA, Low, MSS. Foliis (6" longis) crasse coriaceis longe petio- 
latis ellipticis, ascidiis magnis crasse pedunculatis cylindraceis basi ventricosis 8-18" 
longis, ore lamellis annularibus distantibus rigidis magnis cristato, collo elongato 
erecto, operculo cordato-rotundato, racemo simplici, rachi pedicellisque ferrugineo- 
tomentosis. (Tas. LXX.) 
Hab. 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 21 inches in dia- 
meter below the mouth, 14 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 
dises which surround the mouth are 4 inch in diameter. 
$ IL. Ascidia magna, curva, basi inflata, medio constricta, dein ampliata, infundibuliformia ; ore maximo, 
latissimo, annulo 0. 
3. NEPENTHES Lown, H. f. Caule robusto tereti, foliis crasse coriaceis longe crasse petio- 
latis lineari-oblongis, ascidiis magnis curvis basi ventricosis medio valde constrictis, 
ore maximo ampliato, annulo 0, opereulo oblongo intus dense longe setoso. (TAB. 
LXXI.) 
Hab. Kina Balou, alt. 6000-8000 feet (Low). 
Å noble species with very remarkable pitchers, quite unlike those of any other species. 
They are curved, 4-10 inches long, swollen at the base, then much constricted, and suddenly
