relation to the inherited organization of the plants. 
Waite‘ describes rather fully and illustrates the abnormalities of 
petalody, pistillody, and catacorolla in certain species of Nicotiana. 
He gives an interesting discussion of the occurrence of catacorolla 
in F, plants of the cross N. Langsdorfii and N. alata, the parents

Blossom abnormalities associated with fasciation have also 
been described and illustrated. Some of these resemble very 
closely certain phases of catacorolla. Waite’ describes fasciation
