BOTANICAL SURVEY— SUGAR GROVE REGION 303 



FLORA 



The Sugar Grove region has been collected over by all of the Bot- 

 anists resident in Central Ohio from the time of Sullivant down. The 

 specimens gathered by later collectors have to a large extent been 

 deposited in the State Herbarium at Columbus until there has accumu- 

 lated a fairly representative, though by no means complete, collection 

 of the plants of the region. The list which follows is mainly a compil- 

 ation of those species represented in the State Herbarium from either 

 Fairfield or Hocking Counties. Some, however, are taken from Bige- 

 low's list (see below) or were noted but not collected by the writer. 

 An effort has been inade to collect all those species whose occurrence or 

 determination any one might wish to verify, but many of the common- 

 est plants, such, for example, as Rumux oMusifolius, were simply noted 

 as seen but were not pressed. For tlie protection of those who use the 

 catalog, however, all species not represented in the State Herbarium 

 are specifically noted. 



The wi'itcr lias not attempted to verify the determinations system- 

 atically, since they were all made by competent authority and most 

 of them were verified by the late Prof. W. A. Kellerman. But when- 

 ever a species has aroused suspicion because apparently out of range 

 or for any other reason, the specimen has been carefully scrutinized. 



There may be grounds for criticizing the writer for including all 

 plants known from the two counties in which the area lies rather than 

 confining the list to plants known to occur in the region proper. Since, 

 however, the region has no sharp boundaries and its limits have been 

 somewhat arbitrarily fixed by the writer it will l)e seen that it would 

 be altogether impossible to determine whether a given herbarium 

 specimen with a more or less indefinite record of locality was collected 

 within its limits or not. The increase in the apparent size of the flora 

 from this cause, however, is not believed to be great, because, except 

 for the special conditions in Buckeye Lake, the country is of sufficiently 

 uniform character to make it probable that any plant reaching either 

 of the counties in which the area lies, occurs at least as a straggler with- 

 in the area, even though it might not be easy to fliid it there.
