INCREASED NUMBER OF ORGANS. 
AN augmentation in the number of parts may arise 
from several causes, and may sometimes be more 
apparent than real. True multiplication exists simply 
as a result of over-development ; the affected organs 
are repeated sometimes over and over again each in 
their proper relative position, and without any trans- 
mutation of form. 
Metamorphy, on the other hand, often gives rise to 
the impression that parts are increased in number, 
when it may be that the stamens and pistils, one or 
both, are not so much increased in number as altered 
in appearance. ‘The double anemones and ranunculus 
of gardens, amongst many other analogous illustrations, 
may be mentioned. In these flowers, owimg to the 
petalody of the stamens and pistils, one or both, an 
impression of exaggerated number is produced, which 
is by no means necessarily a true one. Fission or 
lateral subdivision also gives rise to an apparent 
increase in number; thus, some so-called double 
flowers, the elements of which appeared to be increased 
in numbers, owe the appearance merely to the lacinia- 
tion or subdivision of their petals. 
The French botanists, followimg Dunal and Moquin, 
attribute an increase in the number of whorls in the 
corolla, and other parts of the flower, to a process 
which they call chorisis, and they consider the augmen- 
tation to be due to the splittimg of one petal, for 
instance, into several ;—somewhat in the same manner 
as one may separate successive layers of tale one from 
the other. :
