Polypodium vulgare Linn.

The following specie.s of Li/copocUum was identified in the 

 field : 



Lycopodium selago Linn. 



Found si)arinuly in a few places, particularly on St. George 

 Island. 



]Mr. John M. Holzinger has kindl}^ undertaken the determina- 

 tion of the mosses. In this he has been assisted by Mrs. E. G. 

 Britton of New York. Dr. V. F. Brotherus of Helsingfors, Fin- 

 land, and Dr. C. Warnstorf of Neuruppen, Germany. The latter 

 is sole authority for the Sphagnums, in the list of which, owing to 

 the peculiarities of the nomenclature employed, the word 'forma ' 

 and the name following are inserted as given by Dr. Warnstorf 

 in order to avoid the use of pure quadrinomials. The Dicranum 

 was determined by Prof. C. R. Barnes of Madison, Wisconsin. 



In the case of these Sphagnums I fear a transposition of laljels 

 has taken place, since most of the specimens were collected on 

 St. George Island and only one or two on St. Paul — the latter 

 from Bogoslof hill. 



Species and subspecies preceded by an asterisk (*) were col- 

 lected by Mr. James M. Macoun on St. Paul Island in July and 

 August, 1891, and described as new by Dr. N. C. Kindberg in 

 the Ottawa Naturalist, vol. v, January 12, 1892, p. 179.
