CARDIOSPERMUM. 545 
4. Longitudinal section of seed before it has been placed 
in the ground ; embryo much too distinct. 
8. Seed after having been planted. 
8a. 9, Embryo of ditto detached. 
Oss. It is remarkable, that a short time after the fall of the 
Corolla, the foramen or what seems very like it is opposite the 
hilum, the ovule presenting here a decided aperture, the mar- 
gins of which are truncated, while projecting beyond this is a 
remarkably fine membrane, which I consider to be primine, 
and external, although it is difficult to prove this at this stage 
of its development. Examined at a later stage the ovule 
will be found to be curved on its own axis, the integument at 
this period appears to adhere to the body of the nucleas in 
Small nipple-shaped processes which appear hs indicate the 
normal number of ovula to be three. 
' It is most remarkable that in apparently perfectly develop- 
E. ed seeds, during the dry state, I have not been able to trace, 
Any vestige of embryo. The albumen presents a slight dif- 
. Terence in its tissue along the middle line ; but this is scarcely | 
. &ppreciable. The annexed drawings of the embryo were 
ade from 2 seeds that had been placed in the ground some 
time, 
= Gan there be some plants which may be truly called Cryp- 
tembryonez ? 
The testa is considerably a the cords running along 
ne angles or eminences, they are dr composed of ducts 
ich however are unrollable. 
There is a curious but rather strong resemblance between 
Tu Outside of the testa and the saute as will be Seen 
looking at the sketches.
