that portion of Quebec south of the subaretic 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 
.. the southern limit of Pinus Banksiana (= P. divaricata), "Picea 
a (= P. canadensis), as well, as the northern limit of the tulip 
na Liriodendron tulipifera 
[This delimitation is da a very remarkable one, since the southern 
limit of Pinus Banksiana is indicated by a line e running from the east side of 
Penobseot Bay to the Rangeley Lakes, thence, with a slight dip southward 
at the western edge of the White En across northern Vermont (see 
Sargent, Silva; Dame & Brooks, Handb. Trees N. E.; Hough, Handb. Trees.; 
etc.); the southern limit of Picea EH de RR Casco Bay to north- 
ernmost New Hampshire and northeastern Vermont (see Sargent, Dame & 
Brooks, Hough, ete.); but the northern limit of Liriödendron is marked by a 
line running from the southeastern corner of Worcester County, Massachusetts 
(see R. M. Harper, RHoDora, ii. 122) to the southwestern eorner of Vermont 
(see Brainerd, Jones & Eggleston, Fl. Vt.; also Sargent, Dame & Brooks, 
Hough, ete.). 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 exeluded; if, on the other hand, the 
northern limit of Läriodendron is the boundary, then eastern and central 
Massachusetts and essentially all of Vermont with their forests of 
alba and velutina, Castanea, GN Juglans, ete., become a part of the New 
Brunswick area.

“ The great valley of the St. John River and its tributaries has a 
flora far more southerly i in character than that of northern New Bruns- 
wick.” 
[The author of the Phytogeographie Survey has certainly had some unique 
experiences, for no botanist who has spent years exploring northern New 
England and eastern Canada would expeet to find the woodland Mitella nuda 
in a Cranberry (Vaceinium 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 difhieult 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
