[p. 361] “a) New Brunswick Area.” 
“This area territorially covers Nova Scotia, New Brunswick and 
that portion of Quebec south of the subarctic forest.....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, Liriodendron tulipifera.” 
[This delimitation is certainly a very remarkable one, since the southern 
limit of Pinus Banksiana is indicated by a line running from the east side of 
Penobscot Bay to the Rangeley Lakes, thence, with a slight dip southward 
at the western edge of the White Mountains, across northern Vermont (see 
Sargent, Silva; Dame & Brooks, Handb. Trees N. E.; Hough, Handb. Trees.; 
etc.); the southern limit of Picea canadensis extends from Casco Bay to north- 
ernmost New Hampshire and northeastern Vermont (see Sargent, Dame & 
Brooks, Hough, etc.); but the northern limit of Liriodendron is marked by a 
line running from the southeastern corner of Worcester County, Massachusetts 
(see R. M. Harper, Ruopora, ii. 122) to the southwestern corner of Vermont 
(see Brainerd, Jones & Eggleston, Fl. Vt.; also Sargent, Dame & Brooks, 
Hough, etc.). Thus, if the southern limits of Pinus Banksiana and Picea 
canadensis are taken as the southern boundary of the New Brunswick area, 
most of the White Mountain region is excluded; if, on the other hand, the 
northern limit of Liriodendron is the boundary, then eastern and central 
Massachusetts and essentially all of Vermont with their forests of Quercus 
alba and velutina, Castanea, Carya, Juglans, etc., become a part of the New 
Brunswick area.] 
[p. 366] “Dry barrens [of the New Brunswick Area]. The dry 
barrens, or Moor-Formation are characteristically treeless, but are 
surrounded by pine [spruce?] forests and on such areas grow lichens, 
mosses and ericaceous bushes, forming a heather. Here grow Ledum 
latifolium, Vaccinium macrocarpon, Andromeda polifolia, Kalmia 
glauca, Betula pumila, Lonicera oblongifolia with Eriophorum vagina- 
tum, Carex oligosperma and Orchids, Medeola, Linnaea, Mitella nuda.” 
“The great valley of the St. John River and its tributaries has a 
flora far more southerly in character than that of northern New Bruns- 
wick.” 
[The author of the Phytogeographic Survey has certainly had some unique 
experiences, for no botanist who has spent years exploring northern New 
England and eastern Canada would expect to find the woodland Mitella nuda 
in a Cranberry (Vaccinium macrocarpon) bog; and he would certainly be 
astonished if he went to pick Cranberries and found the heath-bog inhabited 
by Medeola of the rich woods. Incidentally it is difficult to think of any 
habitat in the “New Brunswick Area” (except in alpine and subalpine regions) 
where one can collect Ledum latifolium, Andromeda glaucophylla (A. polifolia 
of Harshberger), Kalmia glauca, Betula pumila, Lonicera oblongifolia and
