OF SUKKIM-HIMALAYA. 3 
15. R. vaceinioides, Hook. fil. (n. sp.) ; fruticulus laxe vage ramosus, caulibus ramisque gracilibus tuberculatis ultimis petiolis 
pedunculis foliisque subtus sparse squamulosis, foliis coriaceis obovatis obtusis emarginatisve superne glaberrimis 
subter pallidioribus, pedicellis subterminalibus solitariis gracilibus, lobis calycinis ovatis obtusis, capsula parva 
gracili curvata 5-loculari, valvis submembranaceis. 
Has. Sikkim-Himalaya; epiphytal, or growing on moist rocks, in very damp places, on the inner and outer ranges. 
Alt. 6-8,000 feet. 7U.? 
A small, very slender, straggling species, sometimes pendulous from trunks of trees, and then two fect long, of 
of a bright green colour, and so like a common Sikkim species of Vaccinium (V. obovatum, Wight, Icon. t. 1193) 
as not to be distinguishable at first sight. 
Stems no thicker than a dove’s quill, scabrid with tubercles, indicating the former position of scales, which still clothe 
the ramuli, petioles, and, more sparingly, the under surface of the foliage. Zeaves coriaceous, three-fourths to 
one inch long, obovate or even spathulate, the lamina produced downwards to the very base of the petiole ; 
upper surface a bright green, lower paler. Peduncles of the fruit as long as the leaves, slender. Calye small, 
but manifestly foliaceous. Capsules curving, narrow, pale-coloured, and membranous, an inch long, scarce one- 
eighth of an inch in diameter, valves linear, torulose, a little scaly on the back. Seeds pale-coloured. 
T have never found the flowers of this singular and very distinct little species. 
16. R. pumilum, ook. fil. Tas. XIV. 
Has. Sikkim-Himalaya. Zemu and T’hlonok rivers, rare. Elev. 12-14,000 feet. 
IV. Calyz small or obsolete, rarely 5-toothed, lobes equal. Corolla campanulate, or with the limb contracted 
below its base, and subinfundibuliform. Stamens 10. Ovary 5-10-celled—Shrubs, generally glabrous 
or clothed beneath, sometimes lepidote. 
17. R. arboreum, Sm. Exot. Flora, t. 6. (supra p. 6), not Wight, Ic. t. 1201. 
Has. Himalaya Mountains: from Bhootan to the western extremity. Elev. 5-8,000 feet. 
18. R. Campbellie, Hook. fil. ‘Tas. VI. R. Nilagiricum, Hook. Bot. Mag. t. 4381 (not Zenker).—var. B. flore albo. 
R. arboreum, album, Wall. Ic. Rar. Ind. Or. vol. ii. p. 23. t. 123? 
Has. Sikkim-Himalaya ; on both the outer and inner ranges, at elevations of from 7—-10,—and even 11,000 feet.— 
8. Mountain of Sheopore in Nepal. Dr. Wallich. 
Note. It has been already stated that the chief difference between this and 2. ardoreum consisted in the rusty 
dull (unpolished) tomentum of the underside of the leaf of 2. Campbellia, as compared. with the silvery compact 
filmy clothing of the latter. Dr. 'T. Thomson assures me that in Western Himalaya, where R. arboreum is 
so common, it is never otherwise than silvery and white beneath. Since I have seen the figure of R. Nilagiricum 
in the Botanical Magazine, Tab. 4381, T am quite disposed to consider the present species identical with that, 
exactly agreeing with that in the shape of the leaves, as well as in other characters, and since that is 
acknowledged to have differently-formed leaves from the true 2. Nilagiricum of Zenker, and also said to be from 
Nepal, not from the Neelgherries, we can hardly doubt but that it may safely be brought as a synonym to our 
R. Campbellia: perhaps, also, Dr. Wallich’s 2. nobile (Wall. Cat. n. 1521, excluding 2) is not different, but 
this is nowhere accurately described, and possibly 2. ciznamomeum (which by many is considered a variety of 
#. arboreum) of the same author, from Nepal. I have not seen 2. Campbellie below 7,000 fect, whereas 
R. arboreum, verum, ranges from 5,000 to 8,000 feet. 
19. R. Milagiricum, Zenker, Plant. Nilay. cum Ic. (not Hook. Bot. Mag. t.4381). R.arboreum, Wight, Ic. t. 1201 (not Sm.) 
R. nobile, Wall. Cat. n. 1521. 2 (not 1). 
Has. Neelgherry hills, abundant. Wight, Zenker, and others.
