The insertion of the lateral sepals is at the extremity of the foot of the column, 
and is separated from that of the dorsal by a wide space. The same arrangement 
occurs in В, Wrayt, Hook. fil, The sepals of this are white with spots of red ex- 
ternally; the petals are white; the column pale-ochraceous, spotted with red in front, 
' and the lip and anther are yellow.

Rhizome about *2 in. thick, clothed with brown fibres ; pseudo-bulbs none. Leaves 
rising direct from the rhizome about *5 in. apart, each with a whorl of fibres at the base 
of the petiole; the young leaf at flowering-time invested by a tubular sheath 2 in. 
long; blade oblong, blunt, narrowed at the base into the short petiole; length 6 to 10 
in., breadth 1°75 to 2 in.; petiole 1 to 1°5 in. Scape slender, equal to or shorter than 
the leaf; the peduncle longer than the somewhat decurved spike, with one or two tubular 
shoit sheaths at intervals. Flowers somewhat distant, yellowish, tinged with green and 
streaked with red, :3 in. long; foral bract triangular, acute, longer than the short 
sessile ovary. Sepals 3-nerved ; the dorsal spreading, lanceolate with a broad base, 
sub-acuminate; the lateral pair longer, oblong, obtuse, connate below, free at the apex. 
Petals shorter than the dorsal sepal, oblong with an angularly acute erose apex, 
1-пегуей. Lip as long as the dorsal sepal, elliptic-oblong, blunt, the margins deflexed, 
glabrous, the base with a narrow nectar-secreting groove. Column broad, its apical 
processes broad and 3-toothed, its foot very short. Anther much depressed. | 
Sikkim ; at elevations about 6,000 feet, Griffith (Kew Distrib. No. 5291) ; Pantling 
No. 42; in flower in May and June. 
The spikes of this curious species open from the apex downwards, and are often bent 
at a right angle to the peduncle. The sepals and petals are brownish-yellow flushed 
with green and have purplish nerves; the lip is of the same ground colour, but towards 
the base has many minute purple spots ; the column is greenish, spotted in front like the 
lip. Hitherto it.has been found nowhere but in Sikkim. To this belongs the Griffithian 
specimen No. 5291 (Kew Distrib.), which has been inadvertently referred in the “ Flora 
of British India” to В. conchiferum, Reichb. fil, a closely allied but pseudo-bulbous 
species inhabiting the Khasia Hills.
