Betula subalpina, Larss. Th. M. Fr. 
This is the shrub or small tree of 
which the so-called "Icelandic 
forests " are chiefly composed. It 
grows about 4-8 feet high. Its 
affinity is with B. alba, Z., rather 
than B. nana, Z., but it is quite 
distinct from both. My specimens 
were unfortunately too immature 
for Dr. Fries to speak with abso- 
lute certainty about them. 
B.nana,Z.,is found withB.subalpina, 
and on the mountains over Akreyri, 
in plenty. 
Salix lanata, L. This shrub, which I 
did not happen to meet with in 
Norway or Lapland, is very fre- 
quent in Iceland.

which is not rare in Iceland, seems
