Examination of the Mount Desert material shows much of it to be 
this variety. 
DECODON vERTICILLATUS (L.) Ell, var. LAEviGATUS T. & G. The 
stations for this variety at Isle au Haut and Deer Isle are northeast- 
ward extensions from Kennebec County. 
EPILOBIUM ADENOCAULON Haussk., var. PERPLEXANS Trel. A col- 
lection at Hat Island near Swans Island is the first made in the state. 
CORNUS CANADENSIS L., var. INTERMEDIA Farr. A bunchberry 
collected in dry soil on the sterile slopes of Mount Champlain on Isle 
au Haut proves to be this variety, which has been known in the East 
only from Labrador and western Newfoundland. 
VACCINIUM ATROCOCCUM (Gray) Heller. This has hitherto been 
known from Orono and from Knox County southwestward. It is 
very abundant in a sphagnum bog at Brooklin and in several swamps 
on Deer Isle. 
MERTENSIA MARITIMA (L.) S. F. Gray. Swans Island and Isle au 
Haut may be added to the list of stations for this plant in Norton's list. 
It is interesting to note that in this region at least, the plant occurs 
only on the outer islands on the more exposed headlands or beaches. 
ACHILLEA LANULOSA Nutt. The Swans Island material is the first 
collection of this plant made in Maine.

eastern United States, extending northward in the northeast to Lake 
Champlain, Vermont, Grafton County, New Hampshire and southern 
Somerset and Penobscot Counties in Maine; i. e. in New England its 
northern limit is at about latitude 45°, its eastern limit at the Penob- 
scot Valley. North and east of this limit Aster linariifolius is ex- 
tremely rare and much of the evidence of its occurrence is open to 
serious doubt, although it is listed in Macoun’s Catalogue from three 
regions: “ Newfoundland. (Cormack.) Nepisiquit River, N. B. Rather
