the surface of the earth, and there strike root, after which they 
rise from six to twelve inches nearly erect, and bear numer- 
. ous, approximate fascicles of small, sessile, scaly, proliferous 
bulbs. Bulbs oblong, green, the size of a small berberry, 
vegetating readily when committed to the earth; when they 
chance to remain any length of time on the spike, other 
bulbs are formed irrthe axills of the scales, the whole forming 
a little round head of these bulbs. Scales (of the bulbs) im- 
bricated, ovate, each ending in a pretty long, hooked bristle, 
by which they readily adhere to whatever touches them, and 
thereby are widely spread.

Herbaceous, stemless. Roots tuberous, turnip-shaped. 
Leaves cordate, sub-repand. Spadia nearly as long as the 
concave spathe. .4nihers many-celled. 
A native of Pegu, introduced by the Rev. Mr. F. Carey, 
into the Botanic garden, where it blossoms during the rains. 
_ It differs from A. montanum, the only species known to me, 
for which it can be mistaken, most conspicuously in the shape 
and nature of the root; in other respects their size and habit 
are much alike. )

Stemless. Root a sub-cylindric tuber. Leaves covlditay

A native of the mountainous forests of the Northern Circars, 
where its root is said to be employed to poison tigers. 
I long considered this to be A.‘macrorhizon, but changed 
my opinion on observing that Forster, who must have seen 
and examained that species in its recent state, says, the flo- 
rets are hermaphrodite ; there being six sessile, twin anthers 
surrounding each germ, and that the stigma is orbicular. 
There are no traces of stamina, anthers or glands round the’ 
germs of my plant; and the —_ inreguladl yal three or four-
