T h i s comes veiy near B. protractum, Hook, fil., but has shorter petals, a slightly
d i f f e r e n t column and lip, a longer and more slenderly stalked ovary, and a much
longer floral bract. B, •protractum has besides smaller pseudo-bulbs. This is also closely
a l l i ed to B. Gamhki, but differs in the points noted under that species. The flowers of
t h i s are of a pale yellowish gi-een, with a blotch of orange on the foot of the column.

d u r i n g July and August ; forms laa'ge tangled masses on trees in damp forests,
T h i s species closely resembles B. leptanthum, Hook. fil. But this has broader floral
bracts, which are not acuminate, l-nerved oblong petals, and longer columnar teeth. It
bas also a much more slender rhizome, shorter pseudo-bulbs, longer and more slender
scapes ; and it is altogether a smaller plant in every respect cxcept its flowers, and
t h e y ai'e longer than those of B. loptanthum.

T h e nearest ally of this species is probably the Bur(ne.se B. stenolvXhon, Par. and
R d c h b . fil., but that has different pseudo-bulbs and leaves. The sepals and petals of this
a r e wliite tinged with orange-red at the tips; the lip and column are yellow or
yellowish-white. It is also allied to B. Gamhlei and to D. leptanthum.

A species near the Burmese species B. apodimi^ Hook, fil., from which, however,
i t is distinguished by the shape and thinner texture of its leaves, by tlie more slender
inflorescence and larger flowers. B. apodum, Hook, fil., has moreover rudimentary
pseudo-bulbs, while this species has no trace of such.
