Notes on Some Introduced Plants, Chiefly in Summit Co., Ohio.” 
By ProFr. E. W. CLAYPOLE. 
The overrunning of the Western world by the flora of the 
Eastern is a fact of such great interest to the philosophical botanist 
that every step in the march deserves notice. As we look back 
we are often unable to determine where a foreign plant first entered 
a given district for want of accurate notes of its earliest appear- 
ance. Hence I have thought it worth while to place the follow- 
ing notes on record. 
The following plants have been known for many years in 
adjoining counties and in some part of Summit, but they have 
recently increased far beyond their previous amount, and threaten 
to become mischievous :—the English Buttercup, Ranunculus 
acris and the Narrow leaved Plantain, Plantago lanceolata. 
The following are in the same condition of distribution, but 
are beneficial rather than mischievous :—Orchard Grass, Dee 
glomerata, Tall Fescue, Festuca elatior. 
Those given in this list are already common in some of the 
* Read before the Botanical Club of the ~ A. A. S. at the Buffalo Meeting, 
August, 1886.
