June. Kj ell man (1. c.) says that in the Norwegian Polar Sea it 
bears cystocarps in August. 
This species does not appear to be very common along the coasts 
of the Faeroes. I found it at the following places: — Str.: Kvivig (!); 
Vaago: opposite Kvivig (!); St. Dim on (!); Syd.: Kvalbo (!). 
PTILOTA C. Agardh. 
55. Pt. pectinata (Gunn.) Kjellm., N. I., p. 219 (174); Rosenv., 
Gronl. Havalg., p. 790; Ptilota plumosa, var. asplenioides Lyngb., 
Hydrophyt. p. 38. 
I have found some examples of this species, most commonly 
small ones, which are undoubtedly typical Pt. pectinata ; usually 
this species is easily distinguishable from Pt. plumosa , as Rosen- 
vinge 1. c. p.790 points out in the case of the Greenland specimens. 
Rut a single example of the Fseroese specimens appeared to be 
intermediate between this species and Pt. plumosa though most 
closely related to the latter. Owing to the occurrence of such 
intermediate forms, Gobi disputes the specific value of Pt. pectinata 
and Kj ell man also mentions having found some intermediate 
forms, but is of opinion that the species ought to be retained. The 
material at my disposal was too scanty to allow me to form any 
definite opinion on this point. 
This species belongs to the sublittoral zone, and has been 
found down to a depth of more than 20 fathoms, but in caves it 
may be met with in very shallow water. It is found both epiphytic 
and growing on rocks, on exposed coast as well as in quiet places. 
Cystocarp-bearing plants were found in June, July and August 
which agrees with what is the case in Nordland (Kleen, l.c. p.20). 
This species is presumably rare along the Faeroese coasts. Bordo: 
Haraldssund (!); Str.: Kalbakfjord (!); Kvivig (!), Thorshavn (Lyngb.), Gli- 
versnaes (!). 
As mentioned above, this species was already found by Lyngbye, 
as the material of Ptilota plumosa var. asplenioides Ag. (Hydrophyt., p. 38) 
preserved in his herbarium turned out on examination tq be small 
specimens of this species. In Rostrup’s list it is called Pt. serrata 
Kiitz. (l.c. p. 84), this determination being probably due to J. Agardh. 
Simmons (l.c. p.264) is therefore wrong in saying that it ought to 
disappear from the list of the Faeroese algae, and also in accusing 
Lyngbye with some confusion with regard to his var. |9 asplenioides , 
which Lyngbye very correctly reports both from Greenland and the 
Faeroes.
