92 Rhodora [May 
The paper opens with an account of the general geographic and 
physical features, followed by a well prepared catalogue of the flora 
of the mainland township of Brooklin and the adjacent insular town- 
ships of Deer Isle, Stonington, Swans Island and Isle au Haut. The 
region is one of great topographic charm but composed for the most 
part of acid rock and consequently with a meagre flora—a total of 
only 612 indigenous species, varieties and named forms, besides the 
usual introductions. On this account it is to be regretted that Mr. 
Hill so closely circumscribed his area, for by including the western 
side of Penobscot Bay with its more varied and often calcareous 
soils—Islesboro, Camden, Rockland, etc.—he would have added to 
his flora hundreds of species such as Deschampsia caespitosa, Agropy- 
ron tenerum, Scirpus occidentalis, Carex aurea, Anemone canadensis, 
Vitis novae-angliae, Dirca palustris, Viola rotundifolia, Galium labra- 
doricum and Erigeron pulchellus, calcicolous or at least scarcely 
caleifuge plants which would have furnished a striking contrast to 
the group of acid-rock species which compose so much of the flora 
on the east side of Penobscot Bay. 
In the compilation of his catalogue the author has shown great 
industry, and alertn:ss to make his records complete and to bring 
them into accord with the !atest critical studies. Aside from its 
great value as a local flora, therefore, the paper is a convenient com- 
pendium of references to recent monographic studies of such plants 
as reach Mr. Hil"s area. In the main the work is carefully done, 
only a few minor points impressing one as inaccurate. For instance, 
Lycopodium clav tum, var. megastachyon is var. monostachyon of the 
Manual but no’. of Greville & Hooker, the latter plant being more 
boreal than ours. Similarly, Potentilla pacifica is not P. Anserina 
L., as the synonymy would indicate, but a distinct plant formerly 
included unde’ P. Anserina. 
The last pirt of the paper, “Phytogeographical Aspects of the 
Flora," is, mo t unfortunately, not of the high grade of the catalogue. 
The author h:.s allowed himself to become fascinated by the alluring 
categories prc vided by Merriam's life zones and has felt obliged to 
thrust almost every species of his flora into a single restricted geo- 
graphic pigeon-hole. The result is what might be expected, for 
any botanist of not too limited experience either in the field or the 
herbarium soon learns that “it can't be done." "The majority of 
plants are not simply " Hudsonian," “Canadian,” “ Alleghanian," 
“Carolinian,’ ete.! Most of them occur in two or more of these 
! Merriam's zones were defined chiefly by the characteristic animals: the H vub- 
SONIAN, "the ncrthern part of the great trans-coutinental forest . . . stretching 
from Labrador o Alaska. . . . In the north inhabited by the wolverine, wood- 
land caribou, moose [probably better ''Canadian''—see Scharff, Distrib. and Origin 
of Life in Am. fig. 3. . . . In the eastern United States . . . restricted 
to the cold summits of the highest mountains"; the Canapran, ''the southern part 
of the great tri.ns-continental coniferous forest of Canada, the northern parts of
