latifolia. On the contrary old mountain-slides are richly covered 
with mosses, and here and there with patches of phanerogams. 
The furrows of the wildbrooks are most often completely naked, but 
soon receive plants from the surrounding vegetation, because tufts 
of the latter tumble down into the furrow. The freshest part of 
the moraines is absolutely devoid of plants. In the older parts, 
from which the ice has retired, small sandy spots are found depo- 
sited by the névé-brooks showing minimal specimens of Salix glauca, 
Oxyria, Trisetum, Chamaenerium latifolium, Poa alpina, Anthelia 
julacea, Amblystegium exannulatum and Stereocaulon denudatum. The 
sides of old moraines are most frequently covered with Stereocaulon, 
Salices and Trisetum, but may be bare of plants due to recent 
relaying. | 
The cones of débris consist of coarse gravel with rolled blocks 
relaid every spring by the numerous ramifications of the brook. 
They are covered almost exclusively with Chamaenerium latifolium 
which often dyes the locality red; but in the shelter of blocks may 
be found: Salix arctica, Oxyria digyna and, rarely, Calamagrostis 
neglecta, Silene acaulis, Polygonum viviparum, Carex glareosa and 
Empetrum. 
Bogs (p. 276). 
Three forms of bogs are distinguished: 
1. Tuft-bogs, on gently inclined bottom, nearly dry in the 
high summer. They are made up of Carex rigida, C. rariflora and 
C. scirpoidea; the tufts are 10—30 cm high and are separated by 
grooves, ab. 10cm wide, with Anthelia, Amblystegium stramineum, 
Equisetum arvense f. decumbens, E. variegatum f. anceps and Sphagna. 
2. Flat-bogs with stagnant water during the whole summer- 
period, not dry till the fall. The vegetation is made up by Erio- 
phorum Scheuchzeri and, more rarely, Comarum palustre and Carex 
rariflora. Among the Eriophorum are found numerous Amblystegia, 
Dicranum and Anthelia julacea. 
3. Moss-bogs are found close to brooks in heather-moor, 
round springs, and on the northwest sides of ponds. Their moss- 
flora is noted on page 278. The vascular plants are but few and 
stunted. 
The Strand-Flora (p. 279). 
On the littoral every vestige of proper strand-flora is wanting; 
on the highest summits of the skerries are found gull-tufts made up 
af Carex glareosa, Stellaria humifusa, Poa pratensis, Cochlearia offict- 
nalis f. minor, Sedum rhodiola, Saxifraga decipiens, S. rivularis, Ce- 
rastium alpinum, Polytrichum juniperinum and Grimmia hypnoides. At
