considerably less frequency-degree and physiognomical dominance. 
Lichens were found in all the samples (F °/o 100), but nevertheless 
played physiognomically a less considerable part than in the level 
Dryas-grass-Empetrum-heath. They all occurred on the sides 
of the knolls, while the horizontal surfaces of the knolls were 
covered by phanerogams.

Alectoria ochroleuca and Lecanora tartarea constituted the most 
conspicuous features of the landscape, while reindeer moss, which 
is so common in Danish heaths, was of very little importance there. 
On a knolly heath, in the district around Åsbyrgi, sitting on 
the knolls themselves, I also noted down the following species: — 
Cladonia fimbriata (fruticose lichen; sterile). 
— cariosa ( — ; fertile). 
— pityrea ( — ; sterile). 
Leptogium lacerum (foliaceous lichen; sterile). 
Peltigera venosa ( — » fertile): 
Bacidia flavo-virescens (crustaceous lichen; sterile). 
Psoroma hypnorum  ( ; fertile): 
Lecidea assimilata ( — : fertile).
