which has already been separated off by a transverse wall.

Fig. 5. Young carpogonial branch. In the terminal carpogonium the 
formation of the trichogyne has just commenced. The hypo- 
gynous cell has already formed a marginal cell for the pro- 
duction of the hypogynous disk. On the lowest cell of the 
carpogonial branch has commenced the sprouting forth of the 
enveloping filaments, which subsequently close together to 
form the fruit-wall. x 800.

the just fecundated carpogonium. X 800. 
Fig. 7. The fertilized ovicell (still furnished at the apex with the closed 
neck of the trichogyne) has projected at one side, and developed 
an abundantly ramified tuft of ooblastema-threads (the forma- 
tion of which by no means proceeds from the cells of the hypo- 
gynous disk, as has hitherto been supposed). xX 800.

Fig. 8. Young procarpium from the side. 6, basal cell of the whole pro- 
carpial branch, the penultimate cell (a) of which (the terminal 
cell is bent laterally and in the figure concealed by the cell a) 
becomes the auxiliary cell. This basal cell bears, as a side- 
branch, the three-celled carpogonial branch, the terminal cell 
of which has already developed a long trichogyne, while the 
hypogynous cell has projected very much on one side (A) and 
become abundantly filled with protoplasm. The second cell of 
the procarpial branch bears laterally a sterile side-branch.

Fig. 9. Young procarpium from below. 4, basal cell of the entire pro- 
carpial branch, the joint-cells of which are separated by diffe- 
rently inclined transverse walls, and have nearly all formed 
sterile lateral branches, while the penultimate cell (a) becomes 
the auxiliary cell. The basal cell bears as a side-branch the 
three-celled carpogonial branch, the hypogynous cell (h) of 
which has here remained much smaller than in fig. 8. x 800. 
Fig. 10. Carpogonial branch. In the fertilized carpogonium the ventral 
part is separated and has grown out into a single ooblastema- 
thread (c), which, near its base, has developed a side-branch (c’). 
The ventral part of the carpogonium is completely emptied; the 
hypogynous cell (2) has still abundant contents. x 800.

Fig. 12. Procarpial branch seen from below. The basal cell (6) and the 
neighbouring joint-cell each bear laterally a carpogonial branch, 
of which in the figure only the lowest cell (d) is shown. The 
auxiliary cell (a) had entered into conjugation with the ooblas- 
tema-cell (e), and, after the transference of the whole of the
