indicates 



wide migration westward and southward. The comparative paucity of 

 species in the prairie openings and glades, or at least the absence of colonies 

 of peculiar xerophytic plants of the western and southwestern plains, 

 which constitutes so conspicuous a feature of the typical Ozark region to 

 the north, would seem to indicate that this western plains flora, which 

 under arid conditions unquestionably prevailed over much of the plateau 

 section before the advance of the present forest, did not extend south of 

 the Arkansas River, nor continuously at least, into the more rugged Boston 

 Mountain area. 



Any adequate discussion, however, of these questions would involve 

 a more detailed study of the entire flora, and especially of the herbaceous 

 plants of the glades and barrens, which is beyond our present purpose. 

 It is proposed in a subsequent paper to give an account of some other 

 interesting localities in this part of the region, and to see what light they 

 throw on the history of the Ozark forests.
