(a) Species forming carpets, (b) occurring abund- 

 antly, (c) dispersedly, (d) sparsely, (e) rarely. — 

 Are lichen and moss-heaths met with here otherwise than in 

 small patches, and if so, where? Do these formations occur 

 in sheltered places or in those exposed to the wind? How 

 far up the hills do they extend? How far up does the vege- 

 tation extend as a whole? Which of the lichens are the 

 dominant ones? (In Lapland several varieties of lichen-heaths 

 are met with, formed in different localities according to the 

 strength and desiccating power of the wind). Are the rocks 

 coloured by lichens and algæ ? Photographs of landscapes and 

 vegetation are much wanted, also of single tufts of plants 

 (e. g. large examples of Silène acaulis and the like) and of 

 single plants (e. g. willow, bushes of dwarf birch). 



2. The height of the bushes should be measured. Specimens 

 of the thicker branches should be taken (only a few inches 

 are necessary, but for the sake of the determination, preferably 

 лvith branches bearing leaves attached, or at any rate tied on). 

 It is desirable to get illustrations of the habit (not photographs 

 but drawings of the forms of the bushes, espalier formations 

 etc.). Are there any indications that the forms of the bushes 

 are dependent on the height of the snow-sheet (the branches 

 projecting beyond it being killed by desiccating wind). 



Can any information be had of the extent and duration 

 of the snow-sheet in the interior of the country? 



3. With regard to the marine alga-vegetation the following points 

 should be noted: 



Which species form the main part of the vegetation at 

 each place, both in the littoral region (beach) and in the 

 sublittoral? It will be desirable to get photographs of the 

 alga-vegetation at low water. Also photographs of single large 

 Laminafiaceæ. Information is required as to the duration of 

 the Ice-foot at different places. Does Ascophyllum nodosum 

 occur as commonly in the littoral region as the two Fucus- 

 species {F. vesiculosus og F. inflatus)? Which of the Fucaceæ 

 extends farthest into the fjords? Is Laminaria cuneifolia 

 peculiar to disturbed waters (running water, exposed places, 

 etc.) ? Can this form, which typicahy is quite short-stalked, 

 also occur in forms with longer stalks? Can Agarum Tuneri
