glacialis, and some small tufts of Tortula riiralis; but no 

 coherent vegetation. Above the débris the mountain ascends 

 in broad steps towards the east. On the lower steps the snow 

 still lies in most places metrehigh, and wherever it has melted 

 the bottom is a mire of clay, upon which is rarely seen a 

 Grimmia-tuU, and still more seldom, only in the lee of 

 stones, some few specimens of Luzula confusa, Saxifraga 

 stellaris v. comosa, S. nivalis v. tenuior, Ranunculus glacialis and 

 Oxyria. All here is still thaw and early spring, but even later in 

 the year this cold bottom will house but a very sparse vegetation. 



Higher up the steps become more snowless and are 

 covered by moorland-soil, and here the steep slopes between 

 them, wherever is abundant, equally distributed moisture, be- 

 come densely covered, and if anywhere in the localities a small 

 depression is found, the sides of which protect against wind 

 and weather, one may meet with a veritable herby slope with 

 dense, complete and fresh-green cover of a height of 10—15 

 cm, formed by:

The horizontal flats upon the steps, especially when fa- 

 cing the steeply descending margin, were very moist and covered 

 with extensive flat moss-bogs formed by:
