at northeastern stations of Pine Barren and other Coastal Plain 
species is by no means confined to Newfoundland. In 1880 Pro- 
fessor N. L. Britton! called attention to the fact that many of 
the plants of the New Jersey Pine Barrens extend northeastward 
upon the Cretaceous soil (but not on the Drift) of Staten Island, 
and across Long Island to the similar soils of southern New England; 
and gradually our knowledge of these northeastern outliers of the 
flora of the Pine Barrens and even of more southern highly silicious 
areas of the Coastal Plain has increased until (omitting from consider- 
ation all plants which reach Newfoundland) we now know 118 such 
species which, northeast of Long Island, have remote outlying stations 
along the coastal strip of New England or the Maritime Provinces, 
and every season of botanizing is adding one or more species to the 
list from Prince Edward Island, eastern New Brunswick, Nova 
Scotia, eastern Massachusetts, Cape Cod, Marthas Vineyard, Nan- 
tucket, Rhode Island or southeastern Connecticut. A few examples 
will make clear this class of cases, 118 species, as already said, besides 
those which constitute our Class III, Subclass A of the Newfoundland 
flora. Sabatia dodecandra (S. chloroides), the splendid rosy pink 
gentian of coastal pond-shores from North Carolina to eastern Massa- 
chusetts, is quite unknown on the continent northeast of Cape Cod 
or north of Bristol and Plymouth Counties, Massachusetts, but on that 
remarkable isolated sand ridge and plain, Sable Island, 100 miles out to 
sea from the southeast coast of Nova Scotia, it is “the chief annual ” 
in the flora.2 Aster subulatus is a characteristic plant of coastal flats 
from Florida to New Hampshire, is quite unknown on the coast of 
Maine, southern New Brunswick or Nova Scotia, but reappears 
(with other southern species) in great profusion on the broad flats 
at the mouth of the Nepisiguit River as it enters the Baie des Chaleurs 
in northeastern New Brunswick. lex glabra, the Inkberry of coastal 
swamps from Louisiana to Florida and the Atlantic coast as far 
north as the region of Dorchester Bay, south of Boston, occurs 30 
miles away in an isolated area of swamps in Wenham and Magnolia, 
its most northeasterly station in the United States, but it reappears 
in sandy swamps of southwestern Nova Scotia. Magnolia virginica 
of our southern Atlantic coast extends northward across New Jersey
