and branches low down. The flowers are borne on very short 
scapes, sometimes singly close to a pseudo-bulb, sometimes one 
on each side of a pseudo-bulb, or again, sometimes, at some 
distance from it. They are reversed, 7.e., the lateral sepals are 
uppermost, and open but a little, resembling the head of some 
large-beaked bird. The lateral sepals are dark crimson, and 
meet together by their edges, so as to form a kind of reversed 
boat. The petals are small and inconspicuous. The lip is 
shorter than the sepals, narrow, with a thickened claw, orange- 
coloured, with a crimson groove at the base, and minutely 
papillose. The capsule is very large in proportion to the size 
of the flower, with very well-developed keels.

Belongs to the same set as B. catenariwm, Ridl., but has 
larger bulbs and leaves than any of the species which I have 
seen. The flowers are, however, smaller than those of B. 
coriaceum, Ridl., from Kinabalu. The pedicel of the flower 
lengthens to double its size in the fruit. 
This was found on a tree in a garden in Singapore with 
B. Epicrianthes, Hook. f., and Dendrocolla fulgens, mihi. All 
were said to have been obtained in Singapore, but I think they 
probably came from Sumatra.
