The species was gathered in May — August and October, 

 with sorus in June and July, in a depth of 3 — 19 fathoms. At 

 Ikerasak it grew in a luxuriant vegetation of Lammaria, on a 

 steep rockside, in very rapid current, sheltered by a sea cliff, 

 where no drift ice would normally appear. According to a 

 statement from C.Kruuse the species is common in sheltered 

 places in East Greenland.

У greatest breadth 





The lamina of most of the specimens is broadest below 

 the middle, oblong-ovate ; but sometimes the greatest breadth 

 of the lamina is in the middle, and its shape is narrowly ellip- 

 tical, or the lamina is almost equally broad and linear-lanceolate. 

 The base of the lamina is generally broadly cuneate, sometimes 

 narrowly cuneate or rounded, and in some cases it shows a 

 disposition to the cordate form. The sorus occupies the middle 

 of the lamina in its whole length except the basal part, it is 

 narrow, almost equally broad, or its greatest breadth is in the 

 inferior part, or sometimes in the middle, and then its form is 

 elliptical. The lamina is thin, and its transverse section agrees 

 with Kjellman's description; the middle portion is destitute
