In Cycas circinalis the ovuliferous leaves are of conside- 
rable thickness, flattened above, convexed beneath, and dilated 
towards the apices, the immediate apex being prolonged into 
an acumen. The upper half of the apex is deeply äna 
sharply toothed, the ovules are arranged in cavities below the 
apex along with the margins, and more or less alternately. [t 
is obvious that this arrangement would, if the margins o¢ 
the leaves were produced inwards, produce a carpellum of nor. 
mal male structure. The upper surface of the apex is invariably 
more or less smooth, the pubescence gradually disappearing 
as we proceed upwards, the immediate apex of the acumen 
is smooth, and corresponds to the stigmata of other plants, 
that is, when these are usually alternate with the ptacentz. 
The ovula are roundish, contained in the cup-sliaped 
cavity, flattened obliquely above this, from right to left: 
They may be said to be obcordate; a papilla occupies 
the centre of the sinus. This papilla is short, cylindrical, 
truncate and open at the apex, the margins of the opening 
being somewhat thickened and shining, but apparently des- 
titute of secretion. "Their colour is polished greenish yellow 
and covered more or less with minute glaucido. A transverse 
* Cycas perhaps is the most marked instance of perfection of mere fruit 
with fecundation, all the parts to the albumen being perfectly formed, 
and in abundance, for in C. pectinatus, apparently perfect specimens 
occur, all without embryos, the male being according to Major. Jenkins" 
exceedingly rare.
