shrub at the very highest points of the Adirondack, Green, and White 
Mountains, on the naked-topped mountains of Maine, on Mt. Albert 
and Table-top Mt. in Gaspé, on the rocks of Mt. Desert Island and 
the adjacent coast of Maine, New Brunswick and Nova Scotia; 
thence along the coast of Nova Scotia and the outer coast of Newfound- 
land to Labrador. About the Gulf of St. Lawrence it is somewhat 
local and usually confined to cold bogs or occasional cliffs. In other 
words, south of the St. Lawrence Empetrum nigrum is isolated in its 
distribution, occurring only on the higher mountain-summits and 
on cold coastal rocks or bogs. North of the St. Lawrence, however, 
it becomes one of the commonest of plants, ‘ abundant throughout the 
semi-barren and barren regions of the [Labrador] peninsula, growing 
freely on the coast and inland,"' and according to Delabarre it is 
“the most abundant phenogamous plant of Labrador." West of the 
Labrador Peninsula and Baffin Land it grows, according to Macoun, 
“along the north shore of Lake Superior, and at Port Arthur,.... 
Thence it takes a northwesterly direction and is found in peat bogs, 
on exposed rocks along the shores, and on barren grounds to the 
Pacific Ocean and Arctic Sea."? From the Arctic it extends south- 
ward along the Coast Range to the region of Sitka, and very locally 
on cliffs to the coast of northern California. It is also on the moun- 
tains of southern British Columbia, and locally in Washington; and 
it grows in arctic-alpine regions of Eurasia. Rubus Chamaemorus, 
the Baked-apple of the coastal region of eastern Maine, southern New 
Brunswick and Nova Scotia, is also on the higher White Mts. of New 
Hampshire and the adjacent high peaks of western Maine, but un- 
known on other New England mountains; locally on bogs of Temis- 
couata and Rimouski Counties, Quebec, and on Table-top Mt. in 
Gaspé. From these isolated areas south of the St.. Lawrence it extends 
northward along the outer coast of Newfoundland, and from the north 
shore of the St. Lawrence “everywhere throughout Labrador to beyond 
the tree limit" *; through Arctic and subarctic regions to Alaska, 
coming south along the Coast Range to the region of Sitka. Many 
other characteristic plants of the isolated alpine or colder areas of
