Sikkim ; at Mungpoo, elevation about 3,000 feet; King; Pantiing, No. 322; in flower 
in July. Khasia Hills; elevation 4,000 to 5,000 feet; Griffith, Hooker and Thomson

This comes very near В. protractum, Hook. fiL, but has shorter petals, a slightly 
different column and lip, a longer and more slenderly stalked ovary, and a much 
longer floral bract. В. protractum has besides smaller pseudo-bulbs. This is also closely 
allied to В. Gamblei, but differs in the points noted under that species. The flowers of 
this are of a pale yellowish green, with a blotch of orange on the foot of the column.

Sikkim ; on Engo, elevation from 5,000 to 7,000 feet; Pantling, No. 219; in flower 
during July and August; forms large tangled masses on trees in damp forests. | 
This 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 
has also a much more slender rhizome, shorter pseudo-bulbs, longer and more slender 
scapes ; and it is altogether a smaller plant in every respect except its flowers, and 
they are longer than those of B. leptanthum.
