IN CALOTROPIS PROCERA, 47 
involuted margins, producing large placentz; no trace of 
ovula are distinguishable. 
The filaments or corona staminea next begin to be deve- 
loped, the processes at this time existing in the form of two 
elevated oblong gibbosities, one on either side of the central 
line of the anther, and becoming above continuous with the 
base of this. They also have contracted adhesion between 
each other, a triangular space with thickened sides remaining 
in the upper half, but not admitting a view of the ovary. Pl.

The anthers have almost their mature form, but not con- 
_sistence. The margin of the anthers from the lower part of 
the angle passes in towards the processes leaving between 
them a triangular space, the lower margin of which has a 
thickened growth. The cells are very distinct, and will be 
found to contain a mass by which they are rendered turgid, 
which escapes readily, and consists entirely of an aggrega- 
tion of large and minute granular matters, held together in 
some inappreciable manner. Still earlier and the whole 
contents are mere grumous, in which 3; detects few granules; 
when the cell is so filled, the membrane of the same may be 
detected lining the cell, and adhering to its walls. 
- It becomes much more pronounced when the aggregation 
and segregation of the granules takes place. 
The ovaria have undergone no particular change, the fur- 
rows of the stigmatic angles now present traces of the glands 
in the form of two linear adhering bodies, like coagulated 
mucus, darkish brown along the inner 3, whitish along the 
outer margin. The stigma will be found to have, as indeed 
at the former period, a lisse aspect except its upper surface, 
which has a cellular one. A transverse section shews, that the 
whole of its sides and surfaces except the upper, is occupied 
by stigmatie, tissue, equally distributed, but ceasing gradu- 
ally towards the site of the articulation, which is complete. 
The placenta presents no traces of the development of 
ovula. 
The next stage presents the coronal processes, gibbous 
. » and closed at the bottom, but not recurved.
