EUPATORIUM ROTUNDIFOLIUM IN OHIO. 



Robert F. Griggs. 



The known range of Eupatorium rotundifolium L. would not 

 lead one to expect to find it anywhere in Ohio. The writer was, 

 however, fortxinate enough to find it in an old field about a mile 

 north of the discontinued postoffice at Cedar Grove a few miles 

 east of South Bloomingville, Hocking Co. Here it occurs in 

 great abundance though not seen in other parts of the Sugar 

 Grove area. The plants were entirely similar to the northern 

 representatives of the species preserved in the herbaria but like 

 them differed somewhat from some of those collected in the 

 southern portion of the range. 



The range of the species as given in the manuals is: Rhode 

 Island to Florida, Texas and Kentucky. The Gray Herbarium 

 has specimens from New Jersey, Delaware, District of Columbia, 

 Virginia, both coastal plain and mountain, North Carolina (Hen- 

 derson Co. on the coastal plain and Biltmore in the mountains), 

 Georgia, Florida, Mississippi, Texas ("prairies Rusk Co."), 

 southwestern Arkansas, and Tennessee. In Pennsylvania it is 

 reported by Porter from the coastal plain only but Shafer gives a 

 record, unsupported by herbarium specimens, from Allegheny Co. 

 I am indebted to Professor Femald for the information that its 

 range is now known to extend northward to the vicinity of Boston 

 where it has recently been discovered though at the time of writing 

 the record has not been published nor is the specimen available. 

 The Ohio station extends the range known therefore about two 

 hundred miles.
