208 Rhodora [OCTOBER 
(1885), and xx: 409 (1893). These lists are of course far from com- 
plete, and represent only the results of a few short visits to the 
islands. E 
All visits are necessarily short, for access to the islands is diffi- 
cult for many reasons, and landing on the rocky shores is uncertain 
at any time. It is only therefore by a compilation of the results of a 
number of these hurried botanical observations that sufficient infor- 
mation can be obtained concerning the plants found there for compari- 
son with those of the inner islands, and of the mainland. The following 
list represents the plants, not contained in Mr. Redfield's lists, found 
by me during a short visit made last summer, with the addition of 
a few plants found at other earlier visits. 
It may be said that thus far Cerastium arvense and Montia fon- 
tana are the most interesting plants discovered on these islands. 
The former plant, although common on Great Duck, is unknown 
elsewhere in the region, and doubtless was introduced by some cause. 
The latter plant is unknown elsewhere in the eastern United States 
except on Great Cranberry Isle, some miles further inshore. 
It should be here noted in regard to Mr. Redfield’s lists that Po/y- 
gonum incarnatum there recorded, is an error; and that for Pre- 
nanthes alba, we must probably read, Prenanthes serpentaria, Pursh. 
These corrections were made by Mr. Redfield himself at the time of 
preparing the Flora of Mt. Desert for publication.
