230 Contribution to a Statistical Study of the Cruciferce 
we must classify those in which secondary chorisis has given rise to more than 
the accepted number. 
Let us take stamens 5 and 6 as our basis, i.e. those individuals in which 
position 5 . 6 is occupied by more than two stamens. 
The relative frequencies of the different types of variation in the androecium 
in the 618 specimens so far considered (see Table C) are very interesting. 
The number 1062 in Table F refers to 1062 flowers in which the androecium was
