5. Kirkebo on Stromo; Bo sown with foreign grass-seed. 

 Dominant species: Phlenm pratense, Holciis lanatiis and Festiica pratensis; 

 in piaces Poa trivialis and Ågroslis viilgaris. Ranuncnliis repens and 

 Trifolium pratense dominate in the bottom. Other species noted : An- 

 thoxanthum, Rumex domesticus (isolated), R. acetosa, Cerastium vulgare, 

 Trifolium hybridum, Bellis, Dactylis, Alopecurus pratensis and Poten- 

 tilla anserina — a motley mixture of indigenous and foreign species. 



6. Bo at Sjov, Stromo. Dominant species: Holcus lanatiis, 

 Agrostis, Anthoxanlhiim and Holcus mollis; subdominant: Equisetum sil- 

 vaticum and Trifolium repens; scattered: Rumex acetosa, Ranunculus 

 acer, Angelica silvestris, Luzula multiflora, Plantago lanceolata and Alec- 

 torolophus. On the whole this Bo has few »flowers« and hardly any 

 moss in the l)ottom. 



7. A younger Bo at the same place as the preceding. 

 Dominant species: Holcus mollis and Ranunculus acer; subdominant: 

 Holcus lanatus, Agrostis vulgaris and Anthoxanthum; scattered: Rumex 

 acetosa, Poa trivialis, Stellaria media and Cardamine hirsuta. 



8. Bo in Thorshavn; the surface sloping slightly, and the soil 

 rather dry. Dominant species: Agrostis vulgaris, Anthoxanthum and 

 Holcus lanatus; subdominant: Rumex acetosa, Plantago lanceolata, Luzula 

 multiflora, Ranunculus acer and Alectorolophus; scattered: Cerastium 

 vulgare, Poa pratensis and Bellis. 



In another Bo Holcus mollis was among the dominant species, but 

 as a rule it is subordinate to the three species mentioned above. 

 As a Bo gets oldcr, Holcus lanatus gradually disappcars. 



9. Bo at Næs parsonage, Oster 6. Dominant species: Agrostis 

 vulgaris and Holcus lanatus; Anthoxanthum is subdominant. Scattered 

 species: Rumex acetosa, Holcus mollis, Ranunculus acer, R. repens, 

 Luzula multiflora, Poa trivialis, Carex Goodenoughii, Juncus lampocar- 

 pus, Caltha, Equisetum arvense, E. palustre. 



10. Bo at Klaksvig, Bord 6. The fieids on the whole are moist 

 and poor in »flowering« herbs; and this example is typical of most of 

 the northern istands (Nordreoer). Dominant species: Agrostis vulgaris, 

 Anthoxanthum, Luzula multiflora, Rumex acetosa, and Ranunculus acer. 

 Other species noted: Holcus lanatus, Alectorolophus, Alopecurus geni- 

 culatus, Epilobium palustre, Poa trivialis, Caltha (mostly in the ditches), 

 Holcus mollis, Ranunculus repens, Cerastium vulgare, Lychnis flos cu- 

 culi, Equisetum silvaticum, Juncus lampocarpus. Viola palustris, Carex 

 Goodenoughii and Potentilla erecta. Abundance of moss in the bottom. 



The roof vegetation I regard as a special form of the Bo 

 formation. Nearly all the Færoese houses are thatched with turf 

 (see Fig. 195) and this carries a luxuriant verdure which may 

 be regarded as composed of a selection of the piants from the 

 Bo. The grass-turf used is certainly often obtained outside the 

 home-fields, but the relatively dry situation on the roof where it is
