Denprosium ranks in Mr. Brown’s fifth section of 
Orchidew, distinguished by “a terminal moveable lidshaped 
deciduous anther; pollen-masses of a waxen consistence and 
smooth surface; and by its species being nearly all parasi- 
tical.” In the sectional group, the genus is marked by the 
same author, as having “a spurless label connected by a 
joint with the top of the unguislike process, to the sides of 
which the front-petals are attached in such way as to afford 
the appearance of a true orchideous spur; and 4 parallel 
pollen-masses.” Cucullatum is specifically distinguished by 
Mr. Brown, “ as having loosely hanging stems, lanceolate 
taper-pointed leaves disposed in two ranks, peduncles placed 
opposite to the leaves, and generally 2-flowered, and an un- 
divided label with an ovate outline and cowled base.” 
The stem of our plant had been tied up to a garden stick 
for support on its removal to London, and in this position 
it is shown by our draughtsman; but when growing natu- 
rally in its station on the trunks or branches of the vege- 
tables it affects in its native India, the stems are said to 
hang loosely down.
