[It is worth while to compare the foregoing list with the plants found 
upon Mt. Desert Island, some sixty miles to the northeast. Of the species 
which Miss Cook has found upon Monhegan the following have not been 
seen upon Mt. Desert or the neighboring islands, — Helianthemum majus, 
“Rhus copallina, Gentiana crinita, Phegopteris hexagonoptera, and Carex 
aurea, although the latter is reported from Eagle Island in Penobscot Bay. 
Menyanthes, while abundant upon Great Cranberry Isle, is rather rare upon 
the main island of Mt. Desert ; Cerastium arvense has been found only upon 
the Duck Islands some distance seaward; and though Ranunculus bulbosus 
occurs on Mt. Desert it is as yet very rare. On the Duck Islands, as on 
Monhegan, Taraxacum erythrospermum is more abundant than T. officinale. 
Aster cordifolius, formerly known only at Somesville, the oldest permanent 
settlement on Mt. Desert, has recently established itself at more than a 
dozen points upon the Island and is spreading rapidly. — E. L. R.]
