in the Female Flower of Dammara australis. 189 
margins of the pistil was limited, on the one side by the margin 
of its own bract (No. 1), and on the other by that of bract 
No. 6; so that, according to the position to right or left of 
bract No. 6,so is the great wing developed on the right or left 
side of the pistil. Rarely, nearly equal wings are developed on 
both sides of the pistil. 
The “scales” of the cone, as development advances, become 
much broader, with thin auricled margins at the base. A 
great increase in thickness occurs at the angle which the apex 
of the scale makes with the basal portion, so that the back of 
the scale at that part projects as a well-marked gibbosity. 
This thickening is precisely analogous to what is seen in the 
“scales” of Araucaria, where it is also well marked. In the 
furthest developed cone* which I have examined, this swelling 
is so great that the apices of the scales appear almost as if sunk 
among the gibbosities. Almost the only increase in the length 
of the scale, and that is considerable, occurs in its basal por- 
tion. To illustrate this last point, I have given a series of 
drawings representing longitudinal mesial sections of scales 
at different stages. During its growth the form of the cone 
becomes considerably altered. As before mentioned, it is 
oval at first; from this it passes to pyriform (in second sea- 
son ?); and, finally, it becomes oblately spheroidal, or orange- 
shaped. 
In conclusion, I must express my regret that these obser- 
vations are so imperfect. Indeed, I hesitated for some time 
whether I should publish any of these results before I could 
render them in some measure more complete. But when I 
reflected that possibly I might not have another opportunity 
of continuing the investigation, and that what facts I had 
observed were not without importance, I decided upon laying 
them before the Society. 
Although I have not been able actually to demonstrate the 
perfect independence of the two carpels in their origin, yet I 
have shown sufficient to make it highly probable that they 
are so. 
* One of those developed, as I suppose, in the summer of 1859, and picked 
in the middle of last month.
