average number of pistils was 116, the minimum and maximum being

the flowers were nearly all perfect and had a large number of both 
stamens and pistils would suggest that the absence of pistils is due to 
their degeneration through disease or some other cause; and the case of 
the 10 flowers with few pistils and an average of 40 stamens would sug- 
gest that pistils may be replaced by stamens. There was nothing in 
the vegetative parts of any of these plants to indicate disease.—CLAR-
