362 THE CANADIAN NATURALIST. [Sept. 



No. 84. Asplenium alpestre {Hoppe) Metten. Identical with some Californian speci- 

 mens in my herbarium. 



No. 92 a. Allosurus crispus {L.) Bernk. These specimens appear sufficiently distinct 

 from our Crypto^ratnme acrostichoides to give the latter the rank of a variety, though I 

 have in my herbariujn a specimen from California which is identical with one from 

 Scotland. It is singular that some European botanists should insist on the identity of 

 our Pellcea gracilis with this species. 



The Lycopodiaceae and Equisetaceae of Europe are also very 

 fully illustrated, there being seven species of Lycopodiuin (in- 

 cluding L. inundatum, L. aJpinum, L. selaginoldes and L. 

 ffeheticum), seven of Tsoetes, and no bss than twenty-two species 

 and varieti'^s of Equisetuin. Any of Dr. Rabenhorsfs works can 

 be obtained through the publishers of this journal.

The Acrogens of Lake Superior. — Mr. Macoun, of Belle- 

 ville, has lately returned from a somewhat extended botanical 

 tour around the north shore of Lake Superior, which occupied 

 him during July and part of August. By dint of excessive work 

 he has made a large collection, many of his specimens being of 

 great rarity and interest. A catalogue of all the plants noticed 

 and collected by him is in progress, and will probally be pub- 

 lished by instalments in this journal. The Acrogens, being 

 worked up, are here given as a beginning ; and the opportunity 

 to include the species obtained by other collectors, in the 

 same locality, is availed of. I am indebted to Prof. T. C. Porter 

 for a list of the species collected by a party, consisting of him- 

 self, Dr. Bobbins, and Mr. Smith of Philadelphia, who botanized 

 around the south shore in 1 865 — these are marked Port. ; also 

 to Prof. Eaton, for such as are authentically known to him as 

 occurring on the shores and islands of the Lake — his being 

 marked Eat. The mark Gr. is for Dr. Gray, referring to his 

 Manual ; and Ag. is for Prof. Agassiz's work, 'Lake Superior,' 

 (Boston, 1850). Mr. Macoun's own species are marked Mac. 

 His most interesting ferns are Cystea montana, Woodsia hyper- 

 borea, W. glabella, Botrychium matricarice/olium and B. simplex ; 

 while it is remarkable that he did not find Crijpfogramme crispa, 

 Polystichum Ftlix-mas or Woodsia Oregana, which occur on the 

 south shores of the Lake, the first-named being also abundant on 

 He Royale. The personal-name attached to each species (and 

 variety) is that of the author who first gave the specific name here
