mediately beneath the glands, so that the pollinia by 
mere falling can get access to the stigmatic surface. 5. 
The part which corresponds to the stigmatic surface, it 
is greener than the body of the stigma. 
3. In this case fig. 3 the granules appear to be held to- 
gether by something viscid, and are apparently not 
contained in a tube, this is applied to the foramen 
which is near the hilum, and which is indistinct. In the 
figure, it would appear as if the upper part of the ovulum _ 
were filled with these granules, the lower remaining 
empty : no nucleus was visible. 
4. Grains of pollen, one of the component parts has burst 
and sent out 2 short boyaux. 
5. Ovule some time after impregnation, ovarium the length 
of the calyx. "The nucleus is distinct, the foramen is 
more remote from the hilum and sphacelated. 
6. In this ovule a mass of dark grumous matter was 
applied to the foramen, but did not appear to pass into 
it, since it was easily detached. The first rudiments of 
the nucleus are visible, this is filled with granules 
similar to the mobile ones. 
The foramen is indistinct even at a very early period; 
the ovula at this time appear to contain scarcely any 
granules. The hairs of the ovarium which are developed 
Post anthesin are punctuated: they contain likewise 
plenty of green granules; but the punctuated appear- 
ance is independent of their presence, continuing after 
the granules have been squeezed out, they appear to be 
elevated above the common membrane. 
* In Several instances, part of the base of the flow- 
er, and the furrows leading to the stigma, have been 
Covered over with what appears to be a waxy secretion ; 
it is of a whitest colour to the naked eye, the microscope 
demonstrates it to consist of an infinity of granules, 
held together by some denser medium, in all probabi- 
lity it is owing to a solution? of the pollen masses in
