104 DEVELOPMENT OF THE FLOWER. 
Ovaria distinct lamina; with very thick margins, meeting 
in the centre of the style and forming an oblong process: 
all cellular. Pl. 39.—Fig. 3. a, to A. 
. The young grains on their escape seem to be provided 
with an inner membrane, which is filled with the granules. 
. The interruptions of the outer coat are at first very slight, 
but then they become very pronounced, at the same time 
that the spaces falling between appear to assume a flattened 
form : hence the angular appearance. 
After the outer coats are completed the grains re-assume a 
spherical form, the inside appears irregularly grumous, and 
then decided granules are developed: these are the three 
particles; the degrees and rapidity of the action of iodine 
on these depends upon the amount of development, for the 
grumous stage remains fuscescent when the more developed 
are quite violet. 
The pollen grains, when the corolla is 2 longer than the 
calyx, will be found most spherical, 3 folds? and 3 pores ; 
either quite translucent or beginning to look mucilaginous 
from the development inside of granular matter. They are 
very unequal, the smaller ones being still angular, and as if 
shrivelled. These folds look much like interruptions of the 
membrane. oe 
The prolonged action of iodine causes the inner to pro- 
trude almost entirely from the mass ; it is not coloured itself, 
not even fuscescent. ; 
Gmelina asiatica.—The stigmata appear very remark- 
able if viewed in connection with the usual structure in the 
allied families. 
The stigmatic surface is excessively small, terminating 
each division of the common style; it is a marginal surface 
communicating with a large partial conducting canal, which 
runs into the common one just below the bifurcation. ` 
: PL 39.—Fig. 4. Only two flowers were examined, so that the result wants con- 
firmation, particularly as very young flowers present no peculiarity. 
In the Jamun ( Eugenia jambolana ) the stigma is puncti- 
form, purely terminal.
