heathcr-moor on Myggenæs and Store Dimon, »but the conditions 

 for heath were also entirely lacking.« 



The form of heather -moor which appears on the Færoes ought 

 to be called Calluna-E rica-cinerea moor to dislinguish it from 

 the moist heath which Warming and other Danish autliors have 

 named »CaUuna-Erica lieatli«. This last bears much more of the 

 true lieath character, and differs (among other things) in that it is 

 Erica tetralix which occurs, and not E. cinerea. 



In the Færoese heather- moors, numerous herbs and grasses 

 put in an appearance among the healh-shrubs; so predominant may 

 they become at times, that one can no longer use the term heather- 

 moor. In one direction we may have an approach to the grass- 

 slopes described later. In other directions the heather-moor passes 

 over gradually into the grass-moor (see p. 952), or it may present 

 transitions from the heather-moor of the lower regions to the 

 rocky-flat formation and to the Grimmia heath of the mountain- 

 plateaux. 



A few examples may aid towards forming a concept of the ap- 

 pearance and character of the Færoese heath (heather-moor). 



1. Banks of the lower course of the Tra ngisvaag-river, Sydero. 

 Nearly flat stretclies of river alluvium (gravel, sand and clay), and not 

 particularly turfy. These spots are partly covered with pure Caltiina, 

 but the bushes are low and badly developed. The following secondary 

 piants were noted: Anthoxanthum, Succisa, Potentilla erecta, Luzula mul- 

 tiflora, Festuca ovina vivipara, Scirpus caespitosus, Nardus, Empetrum, 

 Thymus and some Grimmia hypnoides. The vegetation here is relatively 

 young and the habitat is unstable on account of the river. 



2. Slopes of the »roches moutonnées« on terrain north of 

 Thorshavn (compare example 3, p. 951). Calliina gives the tone, and 

 after that Empetrum. Secondary species: Erica cinerea, Thymus, Galium 

 saxatile, Potentilla erecta, Plantago maritima, Anthoxanthum, Festuca 

 ovina, Leontodon autumnale, Polygala serpyllacea. Viola silvestris, Lu- 

 zula multiflora, Hypericum pulchrum. Agrostis vulgaris, A. stolonifera, 

 Brunella, Nardus, Juncus squarrosus, Viola palustris, Pinguicula; mosses: 

 Grimmia hypnoides, Hypna and Thyidium. 



3. Outfield at Videreide, Vider 6. Lower part of the north side, 

 south exposure; a slightly sloping undulating and tufted terrain, the 

 peaty soil showing in hollows and drains, because it is imperfectly 

 covered by piants; Campylopus atrovirens, Carex flava, Narthecium, 

 Scirpus caespitosus, etc. The tufts consist of Calliina, Empetrum and 

 Erica cinerea, among which we find: Nardus, Juncus squarrosus, Poten- 

 tilla erecta, Anthoxanthum, Carex panicea. Brunella, Festuca ovina vivi- 

 para, Luzula multiflora, Selaginella, Cerastium vulgare, Polygala serpyl- 

 lacea, Euphrasia sp.. Agrostis vulgaris and Leontodon. 



4. Slope along the northern side of Bordovig (»Skaarene«); the
