whose industrious research includes not only his own personal observa¬ 
tions, but also a careful examination of the various herbaria existing 
in the Dominion, and of the proceedings, reports, and lists that have 
from time to time emanated from the various natural history and 
scientific societies of the Dominion. The work which this volume 
records commenced considerably prior to the opening up of the 
country by modern enterprise, at a time when what are now flourish¬ 
ing communities were vast forests, prairie lands, and swamps, so that 
a true idea could be formed of the primitive flora ; the gradual spread 
of alien weeds, the results of cultivation, reclamations, and the 
like could be watched and their presence accounted for. Hence this 
work will not only be a good foundation for a fuller and more perfect 
Flora of Canada, but a work of standard value for all future botanists. 
Comparing this “Catalogue” with Asa Gray’s excellent “ Manual of 
the Botany of the Northern United States,” it will be found, as might 
be expected, that a great affinity exists between the Flora of the United 
States and that of the Dominion. What, however, appears to the 
writer most interesting is the great number of British plants to be 
found as either native, alien, or introduced plants in this region, some 
of them being wide spread and evidently of very ancient origin there. 
Out of the 2,201 species recorded, about 400 are found also in Britain. 
Of these about 235 are indigenous to Canada, and 161 aliens, being 
either introductions, casuals, or escapes. Many of these alien plants 
have established themselves, and are in some cases somewhat unwelcome 
visitors. A few instances may be given. Ranunculus acris. L., which 
is stated to be a pernicious weed in the eastern provinces and western 
part of Ontario. Brassica Sinapistrum Boiss., a vile weed in cultivated 
fields and waste grounds, from New Brunswick, throughout Quebec and 
Ontario. Capsella Bursa-Pastor is, Moench, found in profusion, w’herever 
there is cultivation, from the Atlantic to the Pacific. Raphanus raph- 
anistrum, Linn. ; a troublesome weed in many parts. Lychnis githago, 
Lam.; wherever wheat is cultivated this weed is found abundant. 
Stellaria media,'With ; introduced into all garden ground from the Atlantic 
to the Pacific. Spergula arvensis , L. ; troublesome in damp fields. 
Chrysanthemum leucanthemum, L. ; an obnoxious weed in many sections 
of the eastern provinces and Ontario. Polygonum aviculare, L.; wher¬ 
ever the smallest settlement is made this weed is sure to appear. 
Chenopodium album, L., is rapidly taking possession of railway banks, 
ditches, and other places, and is used as a pot herb in many places. It 
is known in Canada by the common name of Lamb’s quarters. Many 
others might be mentioned did space permit. 
Of the British species also indigenous to Canada only a few of the 
more rare can be noticed. Myosurus minimus, L., which with us is a 
local cornfield plant, is found there in rocky pastures and arid spots 
occasionally, from Ontario to Vancouver Island. Arabispetrcea, Lam.; an 
alpine plant in Wales and North Britain, is found throughout 
Canada, extending westward to the Kocky Mountains. Cochlearia 
anglica and C. danica, L., are plants of the arctic shores. 
Silene acaulis, L., is found on elevated parts of the Rocky Mountains, 
and throughout arctic and sub-arctic America from Labrador to 
Behring’s Straits. Cerastiumalpinum, L.; arctic America, and adjacent 
islands, Rocky Mountains, etc. Linum perenne, L., is very common 
throughout the prairie regions. Astragalus hypoglottis, L., is abundant 
in the eastern prairie region and north to Peace River, and east of the 
Rocky Mountains. A. alpinus, L., has a wide range from Newfound¬ 
land and Labrador to the Rocky Mountains and northern British 
Columbia. Dryas octopetala, L. ; Rocky Mountains, and over a wide
