Sikkim; iu warm valleys, common; Pantling, No. 23; ia flower in October,
November and December; distributed weitwards to Nopal and eastwards to the Khasia
Hills aud Burma.
The flowers of the Sikkim plant are of a uniform coppery brown, the column
alone bsiag yellow and the petals largely blotched with that colour. In colouration they
thus differ from the Nepal plant as figured by Sir William Hooker (under the name
AnisopeMum Gare'janam) in his Exotic Flora, t. 149. In that figure the sepals aud
petals are depicted as dusky yellow, spotted with brown; the column and petals as
yellow; and the lip as purple. The basal lobes oE the lip are of the" same shape
as in the Sikkim plant; the petals, however, are narrower, unspotted, and with no
appendages on their margins. In spite, however, of these differences, we believe
Sir ^yilliam Hooker's figure and that here given, to refer to the same species.
Sir Joseph Hooker reduces (Fl. Br. Ind. 1. c.) to a variety of this, under the varietal
name oikracea, the plant named B. cuprcum by Lindloy in the Bot. Register, XXIV
(1838), Misc. 95, and figured under that name ia Bot. JIag. t. 5316, This form,
which is found in Burma, has ochraceoua sepals and petals aud a reddish-brown Hp.
In all other respects, except colour, its flowers agree with those of the Sikkim plant as
here figured. Closely allied to this are B. giayobuUon, Reichb. fil,, and B. crassipon,
Hook. fil. The latter species is described and figured in the Bot. Magazine (t. 4166)
as B. Careyanum, from which, however, it differs in having a longer column with
shorter apical teeth, in haviag the side lobes of the lip shoi-ter and blunter, and in
having (according to the figure 4166) shorter racaraes. We have not been able to
find B. crassipes in Sikkim, and indeed its author attributes it only to the Khasia Hills,
althoush in the Flora of British India Sir Joseph Hooker gives it as a native of Sikkim.
B. sicyobulbon was described from Bm-ma by Reichenbach filius, who distinguishes it
from this by its orange-yellow flowers with narrower floral bracts, sub-serrulate petals,
and by its lai'ger pseudo-biiibs. Another species to which B. Careyanmi is closely alHed
is B. Pechei, Oat Bull. This, which has been described and figured by Six Joseph
Hooker (Bot. Mag. t. 72361, agrees with B. Carey mum in its pseudo-bulbs and leaves,
in the length of its donsely-fiowereJ raceme, and in its bracts and sepals. Its flowers
[ire of the same dull colom- as those of the Sikkim form of B. Careyanum hero figured,
and it is probably the same species. A plant (probably belongmg to an undescvibed
species) which recently flowered in the Botanic Garden in Calcutta, and which is
believed to have been received from Burma, closely resembles B. Careyamm, but has
yellow flowers with triangular floral bracts not half so long as the ovaries, a much
longer and rither more lax and more slender inflorescence than B. Careyanum, smaller
petals, and a Hp otherwise like that of B. Careyanum, but with blunt, not acuto, side
lobes. It has also smaller pseudo-bulbs than B. Careyanum, and in this character disagrees
with the description of B. sicyobiilhon. The flowers of this Burmese plant, like those of
B. Careyanum, have a disagreeable odour. The plants mentioned in this paragraph
beloEg to a gi-oup of Bulbophyllum, the lips of which have basal lobes, an unusual
character in the genus. The members of the group differ within very nai-row limits,
and the whole of them want careful study in the field.

BULBOPHYLLUM. 7O
10. BULBOPBYLLUM TEISTB, Reichb. fil. iu Walp. Ann. VI, 253.
Rhisomc about '15 iu. thick, naked. Pseudo-bulbs turbinate with umbonate apices,
close together or "5 to 1 in. apart, leafless at flowering time, "7 to "9 in. in diam. Leaves
two from eacli pseudo-bulb, sub-membranous, flaccid, narrowly oblong, gradually tapering
to tlie acute apex and to the sub-sessile base, 3 to 5 in. long and '6 to '9 in. broad.
Scape 3 to 5 in. long; the peduncle slender, erect, with a few filiform bracteoles,
twice as long as the drooping rather densely flowered raceme. Flowers •25 in. long,
purple; floral bract lanccolate, acuto, as long as the sessile ovary. Dorsal sepal oblongovate,
blunt, concave; the lateral pair longer, cohering to the tips, gibbous near the
base, their margnis incurved. Petals triangulai-, 1-nerved, shorter than tlie dorsal sepal.
Lip stipitate, oblong-lanceolate, the anterior half narrowed to the obtuse apex; the
upper surface convex and with a divided protuberance. CAumn with subulate apical
processes; the foot short, much curved. Anther conical, papillose, with a small inflexed
lip ; polhnia globose, the inner two rudimentary. Hook. fil. Fl, Br, Ind, V, 768.
Sikkim; at an elevation of about 1,500 feet, in the valley of the Teesta; Pantling,
No. 129; in flower in March. Tenasserim, on the Touugoo range; Lobb, Parish and
Berkeley.
A species now recorded for the first time from this province; hitherto supposed to
be confined to Burma. The flowers, except for a line of yellow on the edges of the Hp
and on the ovary, are of a dull purple throughout; the column ia greenish passing into
white and the foot ia minutely spotted with purple. The flowers have a powerful and
fcetid odour. The Burmese B. micranthum, Hook. fil. (Ic. Plant., t. 2048), must come very
near to this.
