 ments of the plant which according to my opinion agrees fairly 

 well with the plant figured by Rosenvinge (1. c. fig. 19). The erect

of cells, usually bear long hairs the base of which are enclosed in 

 sheaths such as are common in the genus Myrionema (cfr. Sau- 

 vageau, 1. c. p. 44); it was presumably this sheath which Rosen- 

 vinge saw and which induced him to write with reference to the 

 hairs: »poussant quelquefois å travers les sporanges vides«. While 

 Rosenvinge observed in the Greenland piants both basal hairs such 

 as are figured by Reinke, 1. c, and hairs on the erect filaments, 

 the Færoese specimens have hairs on the erect filaments only.
