On the occurrence of certain western plants at Columbus, ()hio. By 

 Aug. D, Selby. 



[abstract]. 



It is my purpose in this paper to point out two features of the flora in 

 the vicinity of Columbus, Ohio, which combine to present in it a represen- 

 tation of western plants ; as a result of the one, we find in that locality the 

 beginning of western species, and by the other are to note the compara- 

 tively recent introduction of a good many far-western and southwestern 

 plants, some of which appear there, perhaps, for the first time east of the 

 Mississippi river. 



In Central Ohio there is a marked blending of eastern and western spe- 

 cies of plants ; east and southeast of Columbus but a short distance will 

 bring one into the typical Appalachian flora, while to the westward the 

 entire half of the state is underlain by the great limestone formations and 

 with the outcrop of the corniferous limestone, the first to be met with 

 traveling westward, plants of a well-marked western range begin to appear. 

 This feature was referred to by Prof, J. S. Newberry* in 1859, He points 

 out a peculiar facies due (in part) to the presence of a number of the prai- 

 rie plants of the west here on the eastern limits of their range. 



The following species may be cited as illustrating this fact, all occurring 

 near Columbus : 



Erysimum asperum, Trifolium stoloniferum, Cornus asperifolia. 



Aster azureus, Aster Shortii, Helianthus doronicoides. 



Camassia Fraseri, Bouteloua racemosa. 



But it is to the presence of a number of distinctly western and south- 

 western plants introduced by wholesale, as it were, that more particular at- 

 tention is directed.
