[Vol. Ill, No. 3, 



injury combiued with superabundance of food, and shortening of 

 the leafy axis, have all been suggested and in many cases are 

 supported by apparenth- 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. Kuds 

 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.

 that are reported in the Ohio Check Lis',. The nomenclature is
