Plant Distribution in Ohio. 
4 i 5 
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.
