much lower ; Empetrum nigrum^ rare and without fruit ; 
Galium saocatile, Aira jleocuosa^ Polygala vulgaris, Geum 
rivale, Ruhus Chamoemorus, Pinguicula vulgaris. Tor- 
mentilla officinalis, Gnaphalium dioicurriy Luzula campes- 
triSy Ranunculus acris, much diminished in size, and with 
fewer flowers; Euphrasia officinalis, and Anthoxanthum 
odoratum. 
By the rivulets of this region, the following plants are 
the most characteristic : Saxifraga stellaris, S. oppositifo- 
lia, Epilohium alpinum, Alchemilla alpina, Gnaphalium 
supinum, Veronica humifusa, V. alpina, Stellaria cerasti- 
oides, Poa alpina. 
Farther down, we find Thalictrum alpinum, in its true 
place. Aii'a flexuosa grows in tufts, and of large size. 
Alchemilla alpina begins to disappear in dry places. Oxy-^ 
ria reniformis, which above is small, grows here among the 
rocks to its greatest size. Saxifraga stellaris is still abun- 
dant along the streamlets, as well as Alchemilla alpina and 
Epilobium alpinum. 
The plants of lower situations which have straggled to 
this region are : Calluna vulgaris, which indeed is found 
higher, but extremely stunted, and in general flowerless ; 
Vaccinium Myrtillus, still fruitless ; Vaccinium oliginosum, 
occasionally ; Melica coerulea, of small size ; Agrostis vul- 
garis, Nardus stricta, Viola canina occasionally ; Galium 
saxatile, Sagina procumhens. Campanula rotundifolia, 
Rumex Acetosella, Eriophorum angustifolium, Cornus sue- 
cica, Car ex hinervis, C. pilulifera, C. panicea, Juncus 
squarrosus, Scirpus ccBspitosus, and many other species. 
Farther down, where the mountains expand, we meet 
the plarits common on the heaths of the central districts. 
Juniperus alpina is plentiful in many places ; yet even here 
Vaccinium Myrtillus seldom bears fruit. Arbutus Uva-ursi 
makes its first appearance, together with Erica tetralix^
