The Flora of the Beaches 



The lake beaches are of two types : the sandy or gravelly 

 beaches with a mingling of xerophytic and hydrophytic floras; 

 and the mud beaches with the flora largely hydrophytic. 



As already noted the sand beaches frequently blend with 

 sandy prairie. Almost any of the plants given in columns V 

 and VI of the xerophytic list may be found locally well down on 

 the outer portions of the sand beaches. The lacustrine plants 

 proper are however, usually of the swamp type, and mingled 

 with them quite frequently are the weeds listed with the hydro- 

 phytes. 



The following swamp species, all given in the hydrophytic list, 

 have been collected on the moist sand beaches:
