[Vol. Ill, No. 3, 
injury combined with superabundance of food, and shortening of 
the leafy axis, have all been suggested and in many cases are 
supported by apparently convincing proof. Fasciation to a slight 
degree was produced experimentally by the writer. Sturdy 
seedlings of the lima bean were selected and the plumule 
removed before the cotyledons were wholly expanded. Adven- 
titious buds appeared in the axils of the cotyledons, much crowd- 
ed together and compressed between stem and cotyledons, and 
several of these gave rise to fasciated growths. In this case the 
amount of stored nutrition was that required for the normal 
seedling. Development was arrested by the removal of the 
plumule so that the independence of the plant was delayed. Buds 
were crowded and there were several closely placed together. 
But what the internal disturbances are that give rise to this 
peculiar development even the best of authorities hesitate to state 
positively.
