Far low’s specimens are also destitute of muciparous canals then 
they resemble the present form in no slight degree. 
Thus Laminaria fceroensis , of which the typical form is parti¬ 
cularly characteristic and easily recognizable is owing to the occur¬ 
rence of this form perhaps not so clearly marked off especially 
from L. saccharina, just in the same way as Rosenvinge (»Gronl. 
Havalg.«, p. 846) points out that L. longicruris on account of the 
occurrence of not decidedly typical specimens, is less distinct from 
L. groenlandica and L. cuneifolia. 
The typical Laminaria fceroensis which is undoubtedly the 
largest alga of the Faeroese coast, grows by preference in the most 
sheltered situations; it attains to its highest development at the head 
of fjords and in the narrow sound between Ostero and Stromo. 
As I said before, it develops more vigorously in shallow water — 
in a few metres — where it can reach the surface by means of 
its air-vesicles; but well-developed specimens may also occur at 
greater depths, at about 10 fathoms. Forma sacchariniformis occurs 
at the boundary of the area of distribution of the typical form, 
especially in deeper water where the sea begins to be somewhat 
disturbed. But the species has never been met with in the open 
sea. It grows especially on stony and gravelly bottoms and even 
on quite fine-grained gravel, and in such a case it attaches itself 
by means of its finely divided haptera to numerous small stones. 
Fructifying specimens were found in May, June and July. 
With regard to the size of the plant, I may refer to the 
measurements given in Bot. Tidsskrift (1. c.). 
This is a common species and occurs abundantly in all well- 
sheltered localities: — Syd.: Head of Vaagfjord and Trangisvaagfjord; 
Str.: Kollefjord, Kalbakfjord and in fact everywhere in the sound be¬ 
tween Ost. and Str. from the narrow tideway to the north to about 
Kalbakfjord; further, in Skaalefjord on Ost. During a brief stay in 
the interior of Sorvaagsfjord I searched for it in vain; it is possible 
that this fjord, being open and rather exposed even in the interior, does 
not afford a suitable habitat for this species.
