PHARNACEUM,—PLatTE LVII. B. 
. Ovule at a very early period, tlie primine secundine, 
and nucleus are very apparent. 
Ovule more advanced ; the primine a. has enclosed the 
secundine. The funicle is attached to the ovule 
throughout its whole length. 
Rather more advanced; a slight lobule is visible at 
the apex of the funicle. 
Primine considerably enlarged and narrowed at its 
apex, which embraces the apex of nucleus. The 
elongation of the funicle commenced. 
Elongation still more advanced. This figure shews 
the situation of the ovule, while attached to the 
placenta; a. margin nezt the base of the pericarp. 
More advanced ovule; the funicle has commenced to 
enlarge at its base. 
The funicle has now reached a considerable length, 
and the central dark line is now visible. This line. 
appears late, perhaps not before impregnation ? 
. Ovule completely developed, but not indurated. The 
-funicle has become enlarged below the hilum into a 
a sac, through which the central fascicle passes. 
- Longitudinal section of the sac ; process of the funi- 
cle remaining attached. 
Mature ovulum.

[Hydrocharis morsus. The stomata rare. They exist as 
here represented. 
The hollow lobes of the receptacle are filled with the same 
fibres. Their walls seem to be composed of 2 layers, of which 
the inner is the most lax.]
