CALOTROPIS. 59 
three of those opposite the sepals, three smaller ones are de- 
veloped opposite the petals. Opposed to these, three addi- 
tional anthers are formed 
In the highest state of monstrosity, these addition- 
al processes are distinct, more frequently the anomal 
adhere either entirely or partially to the normal ones. Inthe 
latter case, the base is distinct and opposite the petal. To 
such, there is not an additional distinct stamen, but the 
stamen corresponding to the normal process is increased in 
Size; this depends on the degree of distinctness or cohesion 
of the accidental process. If this is considerably developed 
the anther is nearly doubled in size, I have never observed 
impregnation in these cases.

2. Ovarium etc., in which impregnation has taken place, 
the tubes are seen passing from the pollen mass and 
entering the style; there is a manifest enlargement of the 
ovarium of the same side.

4. Portion of ditto as seen with Ross’s triplet, here the 
external membrane does not appear divided into cells. 
5. Tube separated. 
6. Ovarium, the styles still adhere, but from the great com- 
parative enlargement of the fecundated ovarium, their 
junction is about opposite the centre of the larger ova- 
rium,
