The foregoing is a preliminary report chiefly on flowering 

 plants. A complete catalogue, so far as it can be made with 

 the information at hand, which will include the cryptogams, is 

 in course of preparation. 



After the first part of this list had gone to press collections 

 of plants were received from Mr. G. B. Rigg from Calhoun 

 Co., and from the East Des Moines High School through 

 Miss Julia E. Rogers from Polk Co. 



Notes on some of these are added in the latter part of the 

 list, but the greater number will be reported upon in the sub- 

 sequent catalogue.
