Mr. C. J. Sprague read the following paper, entitled, 



THE BOTANY OF SORGHUM VULGARE. 



Dr. Hayes has placed in my hands a suite of s^^eciniens of the 

 Sorgho sucre, Imphee, Dottrr/m, and Uroom Corn, for examina- 

 tion, at the request of Mr. H. S. Olcott, of Mount Vernon, West- 

 chester Co., N. Y., who presents them to the Society. The 

 points of interest which Mr. Olcott desires to have examined are 

 these : — Whether these plants are or are not of the same species ; 

 whether they will hybridize ; and whether they are likely to 

 lose their peculiarities by careless planting and management. 

 Some varieties possess more of the saccharine secretion than 

 others. Is this excess a specific peculiarity, or the result of 

 varied cultivation of the same species in different localities ?
