Plant Distribution in Ohio. 



415 



plants and animals are common. There are numerous peculiar 

 plant associations on sand hills and prairies and on the lime-stone 

 islands to the north and west of Sandusky Bay. Of interest are 

 fields of Opuntia near Sandusky, the Meibomias of Margaretta 

 Ridge, and the prairie plants south of Lakeside. Stipa spartea is 

 aboundant on Cedar Point and such plants as Bearberry (Uva- 

 ursi) and Prunus pumila are represented by a few individuals. 

 The flora of the entire region is probably strongly influenced by 

 the climatic conditions of the Bay. A list of distinctive species 

 is given below.
