LOCATIONS OF SPECIAL BOTANICAL INTEREST. 



It is hoped that students of Botany will find it more easy to dis- 

 cover the rare plants of our county by the aid of the following table. 

 The best "botanizing localities known to the author are here given. 

 The localities within easy access of Granville are first given and they 

 are also given in greater detail. The numbers correspond to the num- 

 bers on the map which is to be found in the back part of the catalogue. 



(1.) Arbutus Ridge. One mile southeast of Granville, near the rail- 

 road bridge over the Racoon Creek. It is also reached from Centre- 

 ville Street by Clouse's Lane. 



(2.) Spring Valley. One mile south of Granville, between Lancas- 

 ter and Columbus roads but nearer, Columbus road. When this is re- 

 ferred to in the text, both the small swamp, which is near the opening 

 of the valley, and the sides of the valley are meant. 



(3.) Maple Grove Cemetery. Granville. The bank in the south- 

 east corner next to the T. & O. C. R. R. is the portion which is of 

 special interest. More species occur here than in any other portion of 

 the county of ten times its area. 



(4.) Everett's Swamp. Two miles west of Granville near the Wor- 

 thington road a few rods south of the Worthington bridge.
