I, consequently, mention it as from the Fseroes, though I very 
much doubt its occurring there at all as it has never been found 
there, either by Lyngbye or by any investigator since his time, 
e. g. Simmons, Helgi Jons son or myself. It is just possible 
that Mr. Randropp has confused the labels or made some other 
similar mistake. But, on the other hand, I would emphasize the 
fact that it would be strange if Chcetopteris plumosa were absent 
along the Faeroese coasts, it having been found along the coasts of 
the nearest adjacent countries.

This plant occurred on the open coast in a very exposed locality, 
where it grew in rock-pools near low-water mark. Being gathered 
about the middle of May it was sterile. 
Found only near Gjov (Ost.) on the projecting point between the 
village and the large ravine.

var. lubrica (Rupr.) Rosenv., 1. c. 
The cells in the erect filaments of var. typica are very variable, 
being sometimes longer than they are broad, sometimes only half 
as long as their breadth. The thickness of the filaments also varies 
considerably, the latter often attaining to a breadth of 50 p and 
even more; the thickest filament I measured was about 65 p. As 
E. ftaccida has been reported from the Faeroes (see below), one is 
led to think that these specimens with thick, assimilative filaments 
might possibly be small examples of the latter species, but in all 
the specimens which I examined the assimilative filaments tapered 
gradually to the base, and not suddenly, as is characteristic of 
Elachista ftaccida ; the assimilative filaments of the latter are also 
much thicker. 
The main form is an extremely common epiphyte on different 
Fucacece in the littoral zone and occurs both on exposed coasts
