Meiotaxy of the gynecium—Complete suppression of 
the pistil is of more frequent occurrence than that of 
the stamens, hence more flowers become accidentally 
unisexual by suppression of the pistil than by deficiency 
of the stamens. 
In many Umbellifere, e.g. Torilis Anthriscus, Cicuta 
virosa, the central flowers are often male, owing to the 
suppression of the pistil. In many double flowers, 
owing to the excessive multiplication of petaloid sta- 
mens, the pistil is suppressed, in which cases it often 
happens that the flower is depressed in the centre, as 
in some garden varieties of Ranunculus. Schlechtendal, 
in describing a flower of Colchicum autumnale, in which 
the perianth was virescent, says that, although the 
stamens were present, the pistil was absent. 
In proliferous flowers the pistil is often completely 
defective, its place being occupied by the adventitious 
bud or axis. | 
As in other cases of like nature, suppression of the 
pistil is very frequently consequent on fusion of flowers 
or other changes. Thus Morren, relates an instance 
of synanthy in the flowers of Torenia scabra, accom- 
panied by resorption or disappearance of some parts
