FUMARIA. 721 
This, I fnd is Lindley’s view, who however shews that 
the alternation is quite correct, a circumstance which I had 
overlooked. 
3. Stamina. 
4. Ditto. 
The only objection to this binary arrangement is in the 
Structure of the ovarium, this however may be of little im- 
portance if Papaveracez be taken into consideration. But 
if Lindley is correct in saying that all the 6 stamina are 
sometimes distinct, no explanation of the sort will suffice. 
The opposition however resulting from this is so universal, 
that it is probable there are two series of stamina, it is be- 
Sides more consonant with the situation of the bilocular 
anther to attribute it to pressure, rather than the simplicity 
of the lateral ones to dislocation. 
Examined at a very early stage, when the lateral stamina 
are very nearly distinct and free, their situation is evidently 
in pairs opposite to each petal, there is at this period no 
appearance whatever of the simplicity of the bilocular anther. 
The situation of the locnli is such as would result from the 
complete division of a bilocular anther. 
I see nothing in Fumaria officinalis corroborative of Lin- 
dley’s notions as to impregnation, the horns of the stigma 
are opposite to the sepals, and cause the bulging out as it 
were of the bilocular antherz. I can ascertain no twisting 
of the lateral filaments, all the anthers being without excep- 
tion extrorse. The fact is, that the cavity in which the ge- 
nitalia are confined is so limited that no peculiar means 
are necessary to counteract the defect in situation of the an- 
thers, and impregnation is nearly universal. The anthers 
after dehiscence contract much in size, and shortly after this 
operation, they beeome removed from the stigma, which is 
then surrounded by the pollen.
