This species which is extremely common along the coasts of the 

 Færoes was already reported ironi the latter place by Landt, Le. p. 230. 

 Lyngbye writes with reference to it: — »ad insulas Færoenses copiose, 

 nbi rupibus præruptis in superficie maris adnascens summae lluctnum 

 vehementiæ exponitur«. — f. pinnata has beeo found at a few piaces in 

 the fjords, e. g. in Trangis vaagfjord Hosenvinge).

I have only felt justilied in referring a few specimens to this 

 species, and they were all rather small. The specimens in question 

 had a distinctly two-edged mid-rib; and as soon as the latter showed 

 the slightest indication of being four-sided or even if the two sides 

 only ran parallel along a short distance I re ferred the specimens 

 to Alaria esculenta, as young specimens of the latter species often 

 have a mid-rib which must most properly be cailed two-edged. 



This species occurs in fairly sheltered localities where it grows 

 in company with the preceding. Fructifying specimens were found 

 in April, May, June and Octoher. 



It has hitherto been found only in the following piaces: — Ost.: 

 Skaalefjord (!), Saltnæs (H. J.); Str. : Thorshavn (!); Syd.: Trangisvaag 

 (Rosenvinge). 



This species was already found by Lyngbye as J. Agardh's Her- 

 barium contains a specimen gathered by him which according to Agardh's 

 determination (cfr. J. Ag., Spec. Algarum I, p. 144) belongs to this species. 

 Of the genus Alaria Lyngbye's Herbarium in Copenhagen contains some 

 small fragments only, but they all doubtless belong to Alaria esculenta.

This plant varies very much and a large number of forms 

 have been described (see, e. g. Kjellm., 1. c, and Foslie, Ueber die 

 Laminarien Norwegens, p. 90). I think the three above-mentioned 

 forms are distinguishable in the Færoese material. The specimens 

 referred to f. linearis (see fig. 85) are marked by their long, narrow 

 lamina, which is highly rugose and slightly or not at all waved,

 indication of luning changed leaves. the leaves as in the Færoese specimens being 

 worn at the apex and growing gradually younger towards the base.
