species and i variety ; Filices, 29 species and 5 varieties ; Equi- 

 setaceae, 8 species and 8 varieties ; Lycopodiaceas, 8 species 

 and I variety ; Selaginellaceae, 3 species and i variety, and 

 Isoetacese, 2 species. Where the name of a collector is not 

 given, the localities mentioned rest upon published report in one 

 or another of the papers cited after the name of the species, the 

 works not fully cited being brought together in a bibliographic 

 list which follows the catalogue. 



For a reexamination of the Ophioglossaceas I am indebted to 

 Professor L. M. Underwood, who has also done me the favor to 

 look through the entire catalogue. Mr. B. D. Gilbert has 

 examined the specimens of Athyrmm, and Mr. A. A. Eaton has 

 examined and furnished some descriptions for the Isoetaceae 

 ^and Equisetaceae, the varieties of the latter now for the first 

 time recorded as Alaskan being no doubt more properly attribu- 

 table to his acumen in recognizing the more trivial forms in the 

 genus Equisetum than to the paucity of forms observed or 

 brought in by earlier botanists.
