W. glabella , JF. hyperborea , and W. Ilvensis, all widely spread, and 
extending to the Arctic circle, often found in great abundance ; and 
the noble Flowering Fern, Osmunda regalis, is recorded as of common 
occurrence in the eastern half of the territory. 
Of the Club Moss family, 9 species and 6 varieties are recorded. 
Of European species, Lycopodium Selago is not uncommon on moun¬ 
tains and northwards ; L. inundatum is found in swamps, mostly east¬ 
wards ; L. annotinum, L. clavatum, and L. complanatum are spread over 
a wide extent of the territory ; L. alpinum is doubtfully recorded from 
the summit of Gold Range, altitude 6,500 feec ; and Selaginella spinosa 
is widely distributed in wet, grassy places by rivers, and on mountains. 
Of the Quillworts 7 species are found, the European species, 
Isoetes lacustris and I. echinospora , having a limited range, mostly in 
the eastern portion of the territory. 
The remaining portion of Part V. is devoted to Additions and 
Corrections to Parts I.—IV., which occupy 103 pages, and record 155’ 
species added to the flora of Canada since the publication of Part IV., 
raising the total number of Flowering Plants, Ferns, and Fern Allies 
found in Canada to 3,209 species ; of these 2,310 are Exogens, 771 are 
Endogens, and 98 are Acrogens. 
Part VI., which will be issued during the present year, will include 
Characeae, Musci, and Hepaticae, upwards of 1,000 species being now 
recorded. This will be of great interest to all bryologists. 
The author and his coadjutors are to be congratulated on the excel¬ 
lent results of their labours. The difficulties with which they have 
had to contend can scarcely be realised. The vastness of the country 
they have explored, the inaccessibility of many of the districts, and 
the difficulties of travel connected with this exploration, are such as 
to deter any but truly earnest workers; and no praise can be too high for 
the energy exerted in the investigation, and the ability displayed in 
determining the various plants found, and in arranging and classifying 
the materials obtained. 
With the above, and also forming part of the Natural History 
Survey of Canada, is a “ List of Canadian Hepaticae,” by Wm. H. 
Pearson. The author of this is one of our foremost British authori¬ 
ties on the Hepaticae, and this list is the result of the microscopical 
examination of a large collection of Hepaticae made by Prof. Macoun 
in various parts of Canada. To make this record more complete, Mr. 
Pearson has added species recorded by Mitten in the “ Proceedings of 
the Linnean Society,” and other writers. The result is a record occu¬ 
pying 28 pages of letterpress, giving an account of the distribution of 
163 species, several of them new to science, throughout the Dominion 
of Canada. The new and very rare species are illustrated on twelve 
beautifully drawn plates, which render the work doubly valuable. 
This is a very valuable and interesting addition to botanical literature, 
and will be fully appreciated by all lovers of bryological studies. As 
Mr. Pearson observes in his preface, “ The striking feature of the 
flora is its great similarity to that of Northern Europe.”
