. bodies, with the upper and lower margins inflexed, those that 
are opposed to more or less perfect stamina, have no under 
margin, and the upper is developed into a subulate rostellum, 
the length of which varies as the anther is more or less perfect, 
The ovary is normal, i. e. the sterile carpellary leaves are 
opposed to the sepals, the fertile to the petals. 
The stigmata are, so to say, confluent, and the whole of the 
interior of the column below the upper communicating mar- 
gins, is stigmatose. In one instance however the stigmata 
had caught pollen masses, and the result was the formation of 
two stout cords of boyaux, which did not however run straight 
down the interior of the column, but crossed obliquely over 
the stigmatic surface, immediately under the most perfect ros- 
tellum. In another case however, this predilection for a parti- 
cular stigma did not occur. 
The development of the rostellum is in a marked way pro- 
portionate to that of the stamen to which it is apparently 
opposed. The alternation of the parts are thus.

This of course is casually considering the ovarium as tri- 
carpellary. 
This view agrees with what appears to be the general rule, 
that the carpellary leaves alternate with the inner-most series 
of stamina,
