floms, Triglochin paliistre) may be regarded as belonging to the 

 second category given above, and they indicate that the soil is not 

 very saline. 



Tlie taller Carices, on the contrary, are species indigenous to 

 the salt-marshes of Scandinavia from Bohuslen to the Murman-Sea 

 and always in close proximity to the ocean. 



The salt-marsh has an appearance peculiar to itself (see Fig. 175), 

 with its sharply defined »pans« devoid of vegetation save some 

 drifted Enteromorphae. This characterislic feature is familiar in our 

 salt-marshes at home, (compare for inst. Fig. 175 with the picture 

 Fig. 113 of Warming 1906, p. 262). 



Another salt-marsh (with Carex-salina association) was found 

 on the north side of the Trangisvaagfjord at Skarvatange, on a 

 narrow flat tongue lying out in the fjord. The substratum is solid 

 rock covered by a shallow humous soil, closely pernieated with 

 roots and rhizomes. The dominant species were: Carex Goodenoiighii, 

 C. salina, Agrostis stolonifera, Plantago maritima and Leontodon au- 

 tumnale, var. Taraxaci, with Glyceria maritima nearer the shore in 

 hollows in the cliffs. The following species were subdominant: 

 Festuca rubra, Poa pratensis, Armeria, Triglochin palustre, Lychnis 

 flos cnculi and Jnnciis lampocarpus. A number of other less charac- 

 terislic species were also observed scattered in the association. 



A salt-marsh of the same kind was observed on Sydero at the 

 head of Vaagfjord, with Carex salina also dominant. 



Glyceria maritima occurs constantly amongst the coast-clifts of 

 Sydero, where there are hollows with some soil, often enriched 

 with remains of drifted Algæ. This species was also found under 

 similar circumstances, north of Thorshavn, but elsewhere its place 

 was taken by the allied species Glyceria distans. 



As Sydero is the island with the greatest extent of low coast- 

 line, it follows that salt-marshes occur most frequently there. Small 

 areas with Carex-salina association have been observed, however, on 

 other islands, for example on Stromo near Torsvig, and at Ejde 

 and Selletræ on Ostero. Another example was found on the land- 

 ward side of the dune on San do (see pag. 925) at the point of 

 Sandsvatn nearest the ocean, and again at the mouth of the stream. 

 On Bord 6 a fully developed Carex-salina association was observed 

 at Klaksvig, but unfortunately there was no opportunity for a close 

 examination of its constitution.
