390 THE CANADIAN NATURALIST. [Oct, 



A PROVISIONAL CATALOGUE OF CANADIAN 

 CRYPTOGAMS. 



The Editor of this journal is collecting material towards the 

 compilation of an annotated catalogue of Canadian plants which 

 he hopes to be able to publish in the next volume. With a view 

 to direct attention to the subject, he now prints so much of that 

 material as relates to cryptogams ; and takes opportunity to invite 

 contributions towards the proposed work from all the botanical 

 readers of the Naturalist. In all orders, save ferns and allied 

 plants, these lists are of course very incomplete, in view of which, 

 and to facilitate reference, the genera and species have been 

 arranged alphabetically. Should sufficient material accumulate, it 

 is intended hereafter to treat the fungi, lichens, mosses, and liver- 

 worts, as well as the phenogams, after the same manner as the ferns, 

 and to add descriptions to those few Canadian plants which are not 

 included in the last edition of Gray's Manual. 



Cryptogamic plants are classified in Rev. J. M. Berkeley's 

 " Introduction to Cryptogamic Botany," as follows: 

 Class I. Thallogens, (Lindley,) comprising alliance i. alga- 

 les (Seaweeds), alliance ii. mycetales, including A 

 Fungales (Fungi), B Lichenales {Lichens), Class II. 

 Acrogens, (Lindley), comprising alliance hi. chara- 

 CEALES (Charas), ALLIANCE IV. MUSCALES (Liverworts and 

 Mosses'), alliance v. filicales (Filicoid plants). 

 Alliance i. Algales, Lindley. 



Having little to add to what has already appeared in the Naturalist, 

 the editor would for the present merely refer to the contributions of Rev. 

 A. F. Kemp: — those on fresh-water alga?, in vol. iii, 1858, and on marine 

 algae, in vols, v, 1860, and vii, 1862. 

 Alliance ii. Mycetales, Berkeley. A Fungales, Lindley. 

 This list of fungi is very imperfect, and is capable of almost inde- 

 finite extension. It comprises the collections of Dr. W. P. Maclaggan, 

 whose species were determined by Rev. J. M. Berkeley, and those of the 

 Editor, most of whose passed under the eye of Rev. Dr. Curtis of North 

 Carolina. Both collectors confined themselves chiefly to the microscopic 

 forms. Mr. Berkley estimates the number of good species in Britain at 

 nearly 2500.
