something from that region, which he had never found 

 before either there or elsewhere. In the number of rare 

 species, Cedar Point is surpassed by Marblehead, 

 though the latter has a larger area. Altogether the 

 Sandusky district has furnished more than a hundred 

 species and varieties that were not known to be grow- 

 ing wild any w^here in the state, previous to their 

 discovery here. 



FLORA OF THE ISLANDS AND ITS 



ORIGIN. 



With the exception of some of the little ones, the 

 islands of Ottawa county, and Kelley's — the only 

 island belonging to Erie county, — have been visited 

 many times and at different seasons. Of the plants 

 growing on six of the islands in the lake, separate lists 

 have been kept and an attempt made to make them 

 complete. These lists are not published except as a 

 part of the general list of plants comprised in the 

 Sandusky flora, but a fair idea of the results may be 

 obtained from this by bearing in mind that all the 

 plants marked common or abundant have been found 

 on one and, in nearly all cases, on more than one of the 

 islands, except a few which are noted otherwise. The 

 names of plants not common on the mainland but 

 occuring on Kelley's Island and two or more of the 

 Put-in-Bay group are followed by the word — Islands. 

 If found on Kelley's island and only one other, or not 

 on Kelley's the names, of the islands on which the 

 plant has been found are given. The number recorded 

 for each island is as follows : 



Kelley's Island 461. 



Put-in-Bay 439, 



Middle Bass 306. 



North Bass 282. 



Rattlesnake 192. 



Green Island 115.
