with which it agrees in the pseudobulbs, in the narrow 
leaves, long dense-flowered raceme, short bracts, forms of 
sepals and petals, and approximately in the colour of the 
flowers; but it differs in the unspotted sepals, in the very | 
short acute cusps of the top of the column, and the toothed 
auricles of the lip. Whether such small differences, of 
which the only one that can be called structural is that of 
the column, may well be questioned. It is in its favour 
that the minute characters of B. Careyanum occurs in its 
very differently coloured variety ochracea. 
The other species closely allied to B. Pechei are:—B. 
crassipes, which differs in its narrow longer ellipsoid 
pseudobulbs, very short scape, ovoid raceme, yellow 
flowers speckled with blood red, and entire labellar auri- 
cles; B. cupreum, Lindl., has a slender scape, lax-flowered 
raceme, bracts as long as the flowers, acuminate sepals, 
ovate-lanceolate petals, and slender long columnar spurs. 
B. nilgherrense, Wight (Bot. Mag., t. 5050), has much 
broader elliptic leaves, a longer lax-flowered raceme and 
lanceolate columnar spurs; B. sicyobulbon, Par. et 
Reichb. f., has very large conical pseudobulbs, oblong. 
leaves, and linear bracts as long as the flowers. The 
_ Several other species of the group differ more widely from 
the above. I need hardly add that it is only by accurate 
figures that a comparative knowledge of these plants can 
be obtained. 
B. Pechei was received at Kew from the Royal Botanical 
Garden of Calcutta in 1889, and flowered in January, 
1892. Tam informed by Mr. Bull, in whose catalogue for 
1891 the name first appears, that he received it from Mr. 
George Peché, a resident in Moulmein.
