map, i. e. Erie county, and the islands of Ottawa 

 county, with the eastern portion of the peninsula, ex- 

 tending as far west as Port Clinton. Specimens of all 

 the species and varieties have been examined by Prof. 

 C. F. Wheeler, of Michigan, to whom I am indebted 

 also for assistance in the determination of my earlier 

 collections of Cyperaceaa and Naiadacaa, as well as of 

 many puzzling forms found since. 



Furthermore, a collection of most of the rarer 

 species has been deposited in the Gray Herbarium, 

 Cambridge, Mass., and another set in the Ohio State 

 Herbarium, at the University at Columbus, and at both 

 places botanists have examined them to see if there 

 were errors in the identification. 



To Dr. Erwin F. Smith, of Washington, I am also 

 indebted for valuable suggestions and assistance. 



In a region where so many rare native species 

 occur one would expect to find some exotic plants 

 thriving, better than in most places in this latitude. 

 As in the Philippine Islands where it has been intro- 

 duced, so also in Sandusky, the tomato grows wild, 

 coming up like a weed in many places, but especially 

 along the bay shore, where it ripens its fruit } r ear after 

 year. It is difficult in some cases to say whether a 

 species is naturalized or not. Oats grow on the shores 

 of the islands, as well as about the docks in Sandusky, 

 and along roads, but herbs' of which all the specimens 

 found have probably sprung directly from the seeds of 

 cultivated plants, are not included in the catalogue. A 

 watermelon vine with fruit was found on the shore of 

 Cedar Point, and this and muskmelon, squash and 

 pumpkin, on waste ground in Sandusky near the Bay. 

 Peanuts, which are raised in small quantities by many 

 people in and near Sandusky, have been found sponta- 

 neous in two places in the city. Snapdragon, gilli- 

 flower, candytuft, common honesty, petunia, and 

 others, have been found growing in waste places, but
