excavation is visible in the ovulum, in which the embryo (fig. 11.) was 
lodged. 
. Young embryo; the apiculus is the part by which it is attached. 
. The same, highly magnified. 
. Embryo detached at a later period of its growth. 
. Ditto, showing the commencement of the division into cotyledons. 
Ditto, the division still more advanced. 
Albumen detached, one of its (in this case four) cornua cut away 
longitudinally, to show the cavity in which the embryo is lodged. 
The same entire; the apex of the radicle is just visible between the 
bases of the cornua. 
Mature embryo detached ; the slit and the incompletion of the adhe- 
sion of the rather unequal cotyledons are shown. 
Transverse section of a fruit below the situation of the embryo; in 
this case the ovarium has five rounded angles, each of which is pro- 
longed into a horn.
