PROCEEDINGS OF THE OHIO ACADEMY OF SCIENCE. 325 



Academy celebrates its semi-centennial will be much greater than 

 that which we have noted for an equal time just past. By that 

 time taxonomy and morphology will have given us a better 

 knowledge of plants and plant structures and will have placed 

 plant phylogeny on a firmer basis. Physiology and ecology will 

 have passed into stages of greater usefulness. Plant breeders 

 will have given us greatly improved economic plants, and plant 

 pathologists will have taught us how to keep these plants in 

 better health. Beyond these things that seem certain enough, 

 prediction regarding future advance in botany would be quite 

 hazardous.
