gathered by Mr. C.Jensen near Sumbo (Syd.) was notewortby on 

 account of its very long, lanceolate, swollen receptacles (like Har- 

 vey's fig. 2, 1. c.). It bad quantities of bladders. It is this specimen 

 which I have thougbt proper to refer to var. subfusiformis f. lan- 

 ceolata. Near Thorsbavn I gathered a few specimens, which on 

 account of their large, cordate or broadly oval receptacles appear to 

 correspond to Kjellman's f. robusta. Lastly, the Færoese rnaterial 

 contains a great many specimens, which are quite destitute of 

 bladders. Botb for this reason and on account of the very long, 

 almost lanceolate receptacles these specimens when cursorily exa- 

 mined resemble in no slight degree forms of Fucus inflatns, but it 

 is obvious that they do not belong to it, as the conceptacles are 

 unisexual. 



It grows attached to rocks and stones, and occurs in the littoral 

 zone at about half-tide level; it grows by choice in well-sheltered 

 localities, but may also flourish luxuriantly in piaces which are not 

 much sheltered, e. g. in the small inlets (»Skærgaarde«) which occur 

 along the east coast of Stromo between Thorshavn and Hojvig — 

 a comparatively exposed stretch of coast. It is, however, entirely 

 absent from absolutely open sea-shores. At piaces where tides are 

 not felt it grows directly below the surface of the sea in quite 

 shallow water. It thrives excellently in brackish water, e. g. at the 

 heads of fjords where it even occurs abundantly in the streams at 

 the point where they flow into the sea. 



It fructifies d uring summer. Specimens gathered in November 



were sterile, a few found in December bore quite young receptacles, 



and those collected in April had conceptacles which had not as 



yet fully ripened. 



This species is extremely common along those coasts of the Færoes 

 which are either not very much exposed or entirely sheltered. It was 

 first reported by Landt, 1. c. p. 226. 



Fucus ceranoides L. In Hydrophyt. p. 5 Lyngbye reports 

 this species from the Færoes: — »etiam ad insulas Færoenses«. But 

 his herbarium contains no specimens of this species, and as it has 

 not been found since, the correctness of his report is open to doubt. 



Fucus serratus L. is reported by Landt, 1. c. p. 226, who 

 writes: — »Grows every where at the foot of cliffs covered by the sea 

 at high-tide« 1 . But this report must be due to some confusion as 



1 »Voxer overalt paa Klippe-Rødderne, hvor Havet gaar op ved Flod«.
