to them four parallel cells in place of the more usual number 
of two, nor does the analogy of other cognate genera furnish 
any thing opposed to the inference so strongly suggested by 
the present species. 
BEGONIA. Jinn. 
The island of Sumatra abounds with Begonia, a tribe of 
plants which are chiefly found in moist shady situations at 
the foot of hills and in the recesses of forests. Being suc- 
culent herbs they are with difficulty preserved in Herbaria, 
and the specimens are frequently deficient in one or other 
of the parts of fructification. Descriptions from the living 
plants in their native soil are therefore particularly desirable, 
and in this view the following account of the species which 
have fallen under my observation will not be uninteresting. 
They seem to differ from all those described by Mr. Dryander 
in the first volume of the Linnean Transactions, and no 
great additions have been since made to our knowledge of the 
Genus. 
BEGONIA CJESPITOSA. W. J. 
Subacaulis, foliis inzequaliter cordatis angulatis acuminatis 
glabris, pedunculis dichotome cymosis, capsule alis aequalibus 
obtusangulis v. rotundatis. 
At Bencoolen. 
Nearly stemless. Leaves petiolate, oblique, cordate at the 
base, with rounded slightly unequal lobes overlapping each 
other a little, somewhat falcate, rounded and sublobate on 
one side, straighter on the other, attenuated into a long 
acumen or point, spinulose but scarcely serrated on the 
margin, smooth, shining above, pale and punctato-papillose 
beneath; nerves 5—9, branched towards the margin. The 
leaves are of unequal size and vary somewhat in shape, the 
old ones being much rounder and more decidedly lobed 
than the younger ones, which have the point so much 
incurved as to be nearly falcate on one side. Petioles red,
