I have no doubt, but that the styles and stigmata occupy 
their usual place i. e. the dorsum of the leaf, and that the furrow 
running along the venter of the style, which dilates above, giv- 
ing exit to the stigmatic tissue, is the ventral suture, and that 
the ovula are attached to the margins of this, at the apex of 
the cavity of the ovary, and that below this, the placente of 
the same carpel are united, but still present traces of composi- 
tion, and that the only anomaly, if it is one, is that there is 
no trace of the composition of the placentz of the contigu- 
ous carpels. 
In this case the situation of the vasc. bundles of placental 
mass is proper, that *is belonging to the margins, (being 
compound necessarily.) 
If the other explanation that the spaces between the styles 
are the carpel leaves, be assumed, then the line of inflection 
ceases to be margin, or ratheris not along the axis of 
the leaf, asi the case, and the placentze arise from the 
midrib, and bear the ovula, which would be all quite contrary 
toanalogy ; and what is still more important, the stigmatic tis- 
sues, in this case compound, would have no theoretical con- 
nection even in direction with the ovula or placentz, but a 
line continued downward would traverse the centre of the 
ovarial cell.
