of Silène, Polygonum, Oxyria, Salix arctica, Saxifraga oppo- 

 sitifolia f. reptans, Cassiope tetragona, Luzula confusa, Trisetum, 

 Poa alpina and Festuca ovina. All were low and far behind 

 in development; Oxyria f. inst. was here 6 cm high, whereas 

 at an altitude of 250 metres above the level of the sea it 

 reached 31 cm. 



This tract reached up to abt. 100 metres above the sea- 

 level, Bere began the talus proper, which is considerably 

 steeper, strown with big down-slidden boulders, and has numerous 

 dry brooklet beds with considerable gravel walls on the sides. It 

 stretches from 100 to abt. 250 metres' height. It was covered 

 by spare heather-moor which, on the gravelly walls merged into 

 rocky-flat formation of a somewhat drier description than the 

 above-named. Here were noted down: 



Dryas octopetala f. minor, Chamœnerium latifolium, Silène, 

 Alsine biflora, Cerastium alpinum, Draba alpina, D.Fladnizensis, 

 D. hirta, Arabis alpina. Ranunculus pygmœus, Saxifraga cernua, 

 S. decipietis, S. tricuspidata, S. oppositifolia, Vaccinium, Cassiope 

 hypnoides, С tetragona, Rhododendron, Arctostaphylos, Pedi- 

 cularis hirsuta, Oxyria, Polygonum, Salix glauca, Luzula 

 confusa, Car ex nardina, С rigida, Trisetum, Poa alpina, 

 Festuca ovina, Equisetum arvense and F. variegatum. 



At a height of abt. 250 m the firm rock protruded as 

 vertical walls "Hamre", highly intersected by clefts and with 

 minute weathering products at the base. Here were found coherent 

 plant covers, the fresh green colour of which is in contrast to 

 the brownish gray heather-moor below. The cover consisted 

 of: Potentilla maculata, Sibbaldia, Melandrium apetalum, Alsine 

 verna V. propingua, Arenaria ciliata, Cerastium trigynum, Saxi- 

 fraga nivalis, Sedum Rhodiola, Veronica alpina, Cassiope hyp- 

 noides, Phyllodoce coerulea, Campanula rotundifolia, Antennaria 

 alpina f. glabrata, Eriger on uniflorus, Arnica, Taraxacum 

 croceum, Hieracium alpinum, Betula nana, Salix arctica, S. her- 

 bacea, Luzula spicata, Juncus trißdus, Carex scirpoidea {(^ and Ç),
