A74 GYNANDRIA MONANDRIA. Aerides. 
long, and rather more than half an inch broad. Racemes 
lateral, much longer than the leaves, drooping elegantly. 
Flowers numerous, scattered round the whole of the raceme 
in great profusion, small; colour a yellow ground, spotted 
with purple, delightfully fragrant. Petals five, spreading, 
nearly equal, narrow, obovate. Lip between the lower two 
petals, and longer than them, though they are the longest of 
the five, united to the base of the style, by a perfect, short, 
linear claw. Lamina fleshy, horn-shaped, obtuse, perforated 
a little way up from the base and on‘each side of the perfo- 
ration a conical lobe projecting up and inward to the apex of 
the style. Stamina, pistillum and capsule as in the genus. 
4._A. rostratum. Roxb. 
Parasitic, caulescent. Leaves bifarious, linear, channelled ; 
apex premorse. Racemes lateral, longer than the leaves. 
Lip clavate, sac-conical from the apex of the lamina, column 
beaked, with another on the posterior part near the base. 
A parasitical species; in external habit like premorsum, — 
retusum, &c. but smaller, and the leaves more remote from 
each other. Itis a native of the forests of Silhet, where it blos- 
soms in April and May. 
Racemes opposite to the leaves, or solitary, ascending, the 
length of the leaves, many-flowered. Petals five, nearly 
equal, spreading, rose-coloured, the lower two adhering to 
the under side of the posterior part of the lip, as in Dendro- 
ium but forming nothing like a spur, or claw. Lip horizon- 
tal, of the colour of the petals, and about as long as they, cla- 
vate; there is a deep channel on the upper side, which des- 
cane into the conical bag or case, which points down from 
the apex of the lamina, in which before expansion, the re- 
curved part of the beak of the style is lodged, Style or co- 
lumn very short, but continued in a long, ascending, purple 
beak, with a recurved white apex to this apex; the two, 
roundish pollen balls are attached by a white, flat filament, 
which is just as long as the beak, and allows the balls to rest
