exclusively of Gramineae and Cyperaceae: Glyceria maritima f. 

 vilfoidea, G. distans, G. angustata, Carex incurva, Poa pra- 

 tensis, partly f. vivipara and some badly torn and worn tufts 

 of Carex nardina. 



At a somewhat longer distance from the stream grew upon 

 the stony plains: Some tufts of Salix groenlandica, Papaver, 

 Draba nivalis, Armeria, Fe- 

 stuca rubra, Potentilla pul- 

 chella, Dryas, Braya purpur- 

 ascens and Arabis arenicola. 

 The two lastmentioned species 

 evidently thrive well on these 

 localities, whereas most of the 

 other species were greatly 

 damaged by the w ind ; thus for 

 instance the i)ri/as-bushes 

 were always badly worn, with 

 long, white, dead branches 

 trailing flatly over the stones 

 and the gravel. 



Upon the large stony 

 plains, a little farther towards 

 the east (south of the tributary 

 rivulell, which were furrowed 

 by violent northern gales and 



intersected by spring-streamlets (now dried-up) were found, 

 besides the above-mentioned plants some specimens of Ranun- 

 culus glacialis, Luzula confusa, Melandrium apetalum and M. 

 triflorum, Cerastium alpinum, Oxyria, Lesquerella and Potentilla 

 nivea. 



Here and there a few coffin-shaped sandhills rose above 

 the stony plain, 1 — 3 m long, ^/s — Im high, evidently remnants 

 frome rosion, preserved by the aid of the roots from the 

 Salix arctica- or Chainaenerium-iufts which grew upon their 



Fig. 22.
