Maritime Distriet: New Brunswick Area. 361 
elements in it. These species range elsewhere but nowhere form such pure 
growths as in this region. The comparatively few broad-leaved species is also 
a noteworthy characteristic. — Two districts of this region may be distingu- 
ished: the maritime and the lake districts. 
A. Maritime District. 
This district comprises practically all of the country south of the subarctic 
forest, as far, as Narraghansett Bay and northern Connecticut. Its eastern 
boundary is the Gulf of St. Lawrence and the Atlantic Ocean, while its western 
may be set approximately at hake Champlain and the Ottawa River. It poss- 
esses in its flora such plants as occur on the coast and in Salt marshes, etc., 
which the inland district does not have. 
a) New Brunswick Area. 
This area territorially covers Nova Scotia, New Brunswick and that portion 
of Quebec south of the subarctic forest (see page 351). It comprises the 
Laurentian highlands south of 50° N.L. The northern portions of Maine, 
New Hampshire and Vermont (including their mountain ranges) are part of 
this area, its southern boundary being determined by the southern limit of 
Pinus Banksiana (= P.divaricata), Picea alba (= P. canadensis), as well, as 
the northern limit of the tulip poplar, Ziriodendron Zulipifera. 
1. The Forest-formations of northeastern Temperate North America. 
The original forests of Prince Edward Island conform essentially to 
those of Nova Scotia and New Brunswick, as regards species, but their 
distribution is different. The trees indigenous to the island are the following:

charinum Wang.).
