It has already been stated that this type of vegetation does not 

 appear in the typical »Gjove«, but the following example shows a 

 transition from the moister south-exposed type to the dry. 



Tlie ravine near Husum on Kalso (notes by Mr. R. Rasmus- 

 sen, 1905). The direction of the cleft is east-to-west, the ravine being 

 very open and consequently rather dry and v^'ell-situated with regard 

 to light. The species noted were the following: Alchimilla færoensis, 

 Angelica silvestris, Bellis perennis, Blechnum spicant, Caltha palustris, 

 Cardamine hirsuta, Chamaencrium angustifolium, Cirsium palustre, Coch- 

 learia officinalis, Draba incana, Empetrum, Epilobium sp.. Geranium 

 silvaticum, Hieracium spp., Luzula multiflora, Orchis maculatus, Oxyria, 

 Pinguicula, Plantago lanceolata, P. maritima, Polygala sp. , Potentilla 

 erecta, Ranunculus acer (very tall specimens), Rubus saxatilis, Rumex 

 acetosa, Saxifraga caespitosa, S. hypnoides, S. stellaris, Sedum rhodiola, 

 Spiraea ulmaria, Taraxacum sp., Thalictrum, Thymus, Vaccinium myr- 

 tillus, Viola palustris, V. silvestris; altogether 36 species. 



As an example of the dry Hammer of the alpine region I will 

 take the vegetation on ledges with so uth- western exposure 

 on Fugl 6, about 600 m. above the sea. These were unshaded 

 and rather dr}', with a luxuriant vegetation of phanerogams, many 

 arctic species being represented in this elevated habitat. Mosses 

 were few, both as regards species and individuals; Grimmia hyp- 

 noides here, as nearly everywhere on the Færoes, w^as the most 

 conspicuous. The dominant phanerogams were: Alchimilla alpina, 

 A. færoensis, Oxyria, Sednm rhodiola, Silene acaulis, Saxifraga cae- 

 spitosa and S. hypnoides. 



Other species noted: Alchimilla filicaulis, A. acutidcns, Cerastium 

 Edmondstonii, Polygonum viviparum, Salix herbacea, S. glauca, Dryas 

 octopetala. Thymus, Papaver radicatum, Aira flexuosa montana, Luzula 

 spicata, Festuca ovina vivipara, Saxifraga oi)positifolia, S. nivalis, S. ri- 

 vularis (in crevices of the cliffs), Arabis petraea, Thalictrum, Euphrasia 

 minima, Taraxacum spectabile, Saxifraga stellaris, Sagina procumbens, 

 Empetrum, Ranunculus acer, Draba hirta, Cochlearia oflicinalis and 

 Archangelica (a single individual); altogether 33 flowering piants. 



These ledges were not particularly dry, and this, together with 

 their alpine situation, has produced a vegetation somewhat different 

 from that of the two following examples which, in my opinion, are 

 more representative of the dry »Hamre«. 



Hammer o n O s t n æ s , the s o u t h e r n point o f O s t e r 6 ; ex- 

 posure to south and south-west. Among the more conspicuous phane- 

 rogams were: Luzula silvatica, Sedum rhodiola, Plantago maritima, 

 Oxyria, Epilobium alsinifolium (in crevices), Alectorolophus groenlandicus, 

 Hieracium veterascens, Polygala vulgaris Ballii, Chamaenerium angusti- 

 folium. The ferns noted were: Aspidium filix mas, Polypodium vulgare and 

 Cystopteris; Asplenum adiantum nigrum and A. trichomanes both occur 

 here sparsely and are only recorded from this one place on the Færoes.
