 the coast, and these fit in ratlier well with the Færoese.conditions. 

 He gives Calluna as dominant species, refers next to Erica cinerea, 

 and regards as secondary species Jiiniperiis, Polygala serpijllacea, 

 Hypericiim piilchriim, Galiiim saxatile, Enphrasia fgracilis), Biiniiim

in the Færoese heath-formation. There is also a list of dominant 

 species given by A. Bly tt (1869, p. 49) from »Torvemyrene og Lyngen 

 i de vestligste Egne« (turf-moors and heath in the most western 

 tracts). Of the 19 species mentioned there, no less than 14 are 

 common in the Færoese plant-association of a similar type; but the 

 heath of the West-Norwegian coast, so far as I can make out, is a 

 much purer type of Calluna heath than the Færoese. This is the 

 case at all events with the heath-formation around Lerwick on 

 Shetland, which I saw^ for a few hours during a passing visit in 

 1903. The following notes from my diary refer to this: »Undulat- 

 ing ridge on primitive (archaic) rock, north of the town. The vege- 

 tation is typical heath, with Calluna strongly dominant. Aira flex- 

 iiosa, Nardus, Juncus squarrosus, Festuca ouina vivipara, Scirpus 

 caespitosus and Potentilla erecta are rather common, but generally 

 in hollows. The Calluna heath is remarkably uniform. On a 

 somewhat moister soil Eriophorum polystachyum occurs, Calluna
