C. LÆKJAMOT (THE NORTH COUNTRY). 
With the farm Lækjamét as my starting point I had an op- 
portunity of studying the vegetation in a valley in North Iceland 
for some days in the middle of August 1925. The principal types 
of vegetation are the same here as in the south country, viz. melar, 
mo, and myri. The following applies to their distribution. Up the 
sides of the valley, at the top only the melar vegetation is met 
with, lower down there occurs a belt in which the mo prevails with 
spots of melar, but devoid of myri, and at the foot there is a belt 
where the myri vegetation is dominant and where mo and melar are 
only found over small areas. In the bottom of the valley the 
depressions are occupied by the myri vegetation, the more elevated 
areas by melar and mo. Along the banks of the rivers the vegetation 
consists mainly of jadar. Between the vegetation of the valley sides 
and that of the valley bottom there is the essential difference that 
the myri vegetation of the valley sides consists exclusively of halla 
myri (well myri), while in the valley bottom it consist exclusively 
of förmyri (swampy myri). On the boundary line between mo and 
myri, flag mo was met with, both on the valley floor and on the 
sides of the valley. 
Such is the appearance of a transverse section of a vally in 
North Iceland. Unfortunately time did not permit me to investigate 
a longitudinal section. What I have seen fragmentarily would seem 
to show that at any rate the floor of the valley exhibits typical and 
interesting differences, especially as regards the myri vegetation. At 
the head of the valley, where there was no level bottom, the halla 
myri (including the dy vegetation) extended right down to the river. 
This was the case at Adalbol in the Austerädalur. Further out, 
as at Lekjamot in the Vididalur, halla myri is only found on the 
mountain slopes, while the level bottom of the valley is covered 
with the förmyri (including the flöi vegetation). Still further out 
the förmyri seems to have been replaced by the fetmyri, the Carex 
cryptocarpa myri (including the fen vegetation, the Equisetum 
limosum swamp). This at any rate was the case at the mouth 
of the Vatnsdalur. 
Tables 19 A and 20A show the circling results for melar, mo, 
and myri in the neighbourhood of L&kjamöt. The circling results 
for the flag mo are given in table 17 A together with the flag ve- 
getation from the south country.
