HE vascular cryptogams of Greenland have been described by 
Тон. LANGE: Conspectus Flore Groenlandicæ I, IT (Meddelelser om 
Grønland, Kjøbenhavn 1880, 1887) and С. Н. Озтемевьо: Flora Arctica I, 
Copenhagen 1902. The reason of my presenting this list is to collect in 
one work all the Pteridophyta, species and varieties, known from Green- 
land as well as their localities. During a visit to Copenhagen 1917, through 
the ready courtesy of the Museuminspektor Dr. С. H. OSTENFELD, 
I had an opportunity of going through the large collection of ferns from 
Greenland, preserved in the Botanical Museum there. Further I have 
had access to the material contained in the Museums of Stockholm, 
Uppsala, Lund, Kristiania and Bergen.
