unknown east of the lower Androscoggin (see Sargent, Dame & Brooks, etec.); 
Juniperus virginiana is of very doubtful oceurrence east of the Kennebec 
valley (see Dame & Brooks); and Castanea dentata is known in Maine only 
in the southern corner (see Sargent, Dame & Brooks, ete.). Therefore a large 
part of the region described by Harshberger as belonging to the New England 
Area is by the definition excluded from it!] 
[p.- 379] “ Thickets of Alnus maritima also occur according to 
HARSHBERGER’sS observations” [on Peaks Island, Portland Harbor]. 
[It is fortunate that the authority for this remarkable observation is stated. 
The many diseriminating New England botanists who have been on Peaks 
Island have never seen Alnus maritima there. In fact, the reviewer inclines 
to the belief that Professor Harshberger must have mistaken something else 
for A. maritima, for that unique species is not recognized by öther students 
of the trees from any region of our eastern states outside of Delaware and 
Maryland (see Sargent, Hough, Britton, ete.)] 
[p. 385] “ Bog Formation. This formation is characterized by the 
abundance of Sphagnum species which form a dense growth over 
the surface.... They may be called islands of northern plants with 
many ericaceous species. The plants of this formation in eastern 
Massachusetts are: 
Calla palustris L. Sarracenia purpurea L. 
Clintonia borealis Raf. ? 
Habenaria lacera R. Br. Utrieularia cornuta Michx. 
Pogonia ophioglossoides Ker. Epilobium lineare Muhl. (=E.

Limodorum tuberosum L. [i. e hi o[Olxyeoceus L.

: Andromeda polifolia L. 
Rhododendron Rhodora Don. 
[Just why Habenaria lacera (which rarely grows in Sphagnum bogs in Massa- 
chusetts) and Epilobium densum, with a range from Alabama to southern 
Newfoundland, Pogonia ophioglossoides and Utrieularia cornuta, ranging from 
Florida to Newfoundland, and Sarracenia purp a, which extends from Florida 
to southern Labrador, should be considered peculiarly northern it is difheult 
to make out. And surely the author must have seen some other plant than 
Clintonia borealis, for in eastern Massachusetts Clintonia oceurs in cool rich 
woods (see J. Robinson, Fl. Esser Co.; Knowlton, Cushman, Deane and 
Harrison, RHoDorRA, x. 130). ’ 
‚It is unfortunate longer to inform our unsuspecting European friends that 
Andromeda polifolia grows in Massachusetts bogs. The plant of New Eng- 
land is A. glaucophylla Link (see Ruopora, v. 67-71; Gray, Man. ed. 7).]
