H a b . Sikkim-Himalaya; epiphytal, or growing on moist rocks, in very damp places, on the inner and outer ranges.
Alt. 6-8,000 feet. M. ?
A small, very slender, straggling species, sometimes pendulous from trunks of trees, and then two feet long, of
of a bright green colour, and so like a common Sikkim species of Faccinium {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. Leaves 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. Calyx 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.
I have never found the flowers of this singular and very distinct little species.
16. R. pumilum, Hook. fil. T a b . XIV.

below its'base, and subinfundibuliform. Stamens 10. Ovary 5-10-celled.—Shrubs, generally glabrous
or clothed beneath, sometimes lepidote.

H a b . Sikkim-Himalaya; on both the outer and inner ranges, at elevations of from 7-10,—and even 11,000 feet.—
f3. Mountain of Sheopore in Nepal. Dr. Wallich.
Note. It has been already stated that the chief difference between this and B. arboreum consisted in the rusty
dull (unpolished) tomentum of the underside of the leaf of B. Campbelliee, as compared with the silvery compact
filmy clothing of the litter. Dr. T. Thomson assures me that in Western Himalaya, where B: arboreum is
so common, it is never otherwise than silvery and white beneath. Since I have seen the figure of B. Nilagiricum
in the Botanical Magazine, Tab. 4381, 1 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 B. 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
B. Campbelliee-. perhaps, also, Dr. Wallich’s B. nobile (Wall. Cat. n. 1521, excluding 2) is not different, but
this is nowhere accurately described, and possibly B. cinnamomeum (which by many is considered a variety of
B. arboreum) of the same author, from Nepal. I have not seen B. Campbelliee below 7,000 feet, whereas
B. arboreum, verum, ranges from 5,000 to 8,000 feet.
