il has never since been found along the coast of the Færoes and 

 it is hardly possible that il should liave been overlooked. Lyng- 

 bye writes also in Hydrophyt., p. 5, with reference to this species: 

 — »Ad insulas vero Færoenses non reperitur«. 



PELVETIA Dtsne. et Thur.

 Lyngb., Hydrophyt., p. 6. 



As might be expected piants growing at higher levels are small 

 as they there lack sufficient nourishment, and such small examples 

 are especially met with in the interior of fjords. Si m mons, 1. c. 

 p. 296 calls them f. minima, and as pointed out by him they usnally 

 consist merely of a comparatively large receptacle horne on a short 

 stalk; hul they are only to he regarded as stunted specimens. 



This species belongs to the littoral zone and grows near high- 

 water mark or even somewhat above it; it is rare in exposed lo- 

 calities; it requires some sort of shelter as it never occurs on eliffs 

 which are exposed to the full force of the incoming waves from 

 the open sea, but grows in localities which are somewhat protected 

 by rocks standing out in the sea. In such it occurs several feet 

 above high-water mark and is able to endure a longer period of 

 desiccation. It always grows gregariously. I never observed it in 

 rock-pools. 



It was found bearing frnil in May, .lune, July, October and 



December so it seems to be able to fructify almost all the year 



round. 



This species is quite comnion along the Færoes though not every- 

 where, so Ly ngbye's (l.c. p. 6) statement: — »Ad insulas Færoenses hic illie 

 copiose is quite to the point. It was first mcntioned by Landt l.c. p.227. 



HIMANTHALIA Lyngb. 



156. H. lorea (L.) Lyngb., Hydrophyt., p. 36; Kjellm., N. I., 

 p. 242 (193). 



This characteristic species grows at about low-waler mark or 

 somewhat above it, but in particularly exposed localities it mav 

 occur at fairly high levels or at any rate up to some 2 metres 

 above low-water mark. It grows by preference on open sea-shores 

 and is in et with at the most exposed piaces, but it mav also grow 

 in more sheltered localities. Where tides are not felt, e. g. in Skaale- 

 fjord it grows at a depth of a few feet, but does not seem to thrive.
