At a period long after fecundation, the nucleus has near- 
ly disappeared; traces of it are still visible, however, ad- 
hering to the apex of the embryonary sac. 
The upper half contains the densest albumen, and this 
fills the cavity of the testa, the remainder consists of a very 
lax congeries of very irregular cells: the mass tapers to. 
a point, and is connected to the base of the seed by numer- 
ous irregularly articulate threads, this part does not fill the 
testa; the raphe is complete; the cotyledons are alternate 
with it. a 
The cells forming the lower half of the embryonary sac. 
may be observed in every stage of development; form hy- 
aline, minute empty sacs; larger sacs filled with granules, 
which finally become very large, containing apparently rudi- 
ments of cells, at any rate they are tumid at various points ; 
the raphe consists through about its upper two-thirds of 
opaquish tissue, containing a central fascicle of short unrol- 
lable ducts: the lower one-third has no ducts.
