three lobes of the ovary that were absent. The sole 
remaining carpel had a style and a stigma as perfect 
in appearance as though the pistil had been complete. 
In a flower of Conostephium (Hpacridacee) forwarded 
to me by Mr. Bentham, there was a similar adventitious 
bud placed by the side of the pistil, but as the latter 
contained the usual number of cells it is probable that 
the supernumerary bud in this case origimated rather 
from the side than the end of the axis. 
Certain families of plants present this deviation 
from their ordinary structure with greater frequency 
than others: the followimg orders seem to be the 
most frequently affected by it: Ranwnculacee, Caryo-
