1901] Cook, — Plants of Island of Monhegan, Maine. 187 
A LIST OF PLANTS SEEN ON THE ISLAND OF 
MONHEGAN, MAINE, JUNE 20-25, 1900. 
MABEL PRISCILLA COOK. 
THE following list of plants on the island of Monhegan, Maine, 
compiled from the results of the botanizing done during so short a 
visit to the island, and necessarily limited to the plants of that partic- 
ular season, is in no way to be considered a Flora of Monhegan. 
There are very few plants included in the list which were not found 
in bloom. I feel, however, that the territory was very well gone over 
as I had the advantage of the guidance of an old and enthusiastic 
visitor to Monhegan. ‘The sixteen miles of ocean between the island 
and the “main” led me to hope that I might find some especially 
interesting features, in the local flora, so that it was a surprise to find 
what a large number of introduced species were present. The 
absence of salt marshes and of any true beaches eliminates a large 
number of those plants that we expect to find in any list from a sea- 
shore station. A very potent agent in the distribution of plants over 
the whole area of the island has been the presence of large flocks of 
sheep, in whose fleeces the seeds of many distinctly introduced species 
have been carried to the most remote parts of the island. 
It will be interesting to see what effects the severe fire that devas- 
tated the eastern end of the island during the late summer and fall of 
1900 will have upon the flora. A peat-bog in the center of the 
island burned, underground, for weeks, and a large tract of woods 
was destroyed. 
In the following list asterisks have been employed to distinguish 
introduced species, and the sign t indicates plants common upon the 
island. The nomenclature followed is, as far as possible, that of the 
Synoptical Flora. I am indebted to Mr. M. L. Fernald for the de- 
termination of the Carices.
