The above list consists of representatiyes of twenty-seven families, of fifty- 

 four genera, and of seventy-two species. 



Were we to include all the plants ever found on such plains and all found 

 in the neighborhood of the plains we might find, perhaps, nine hundred 

 species, or twelve times as many as are above enumerated. 



The above list is as nearly typical as I am able at present to make it and is 

 the result of repeated studies over a large extent of territory. 



The families of plants best represented on the plains are the Rosacece by 

 nine species, Compositca by fifteen species, Vacciniacece by seven species and 

 ^GraminecB by nine species. 



The following large and prominent families of the state are not represent- 

 ed in the list above given: Ranujiculacecs, cruciferm, caryovhyllacece, saxi- 

 JragacecB, umbelliferm, orchidacem.
