ALPINE FLORA AND FERNS OF NORWAY. 327 



Luzula arcuata may be found here and there, and 

 Diapensia in abundance. 



' On both sides of the road from Jerkin to Kongsvold, 

 over Jerkinshoe, the vegetation is remarkably interest- 

 ing. Perhaps in no other part of the Fjeld are there 

 such good opportunities for noticing the different forms 

 and growths of the very variable willow-tribe. The 

 Primula stricta grows in comparative abundance close 

 to the road side. On approaching Kongsvold the 

 AlsineUa nibella ft hirta, and Artemisia norvegica 

 begin to appear. On arriving at Kongsvold, where 

 excellent quarters are to be had, excursions should 

 be made on the east side of the river. The vegetation 

 of the western side is comparatively poor, although 

 many interesting lichens and mosses may be gathered. 

 Nystudal, a high-lying mountain valley, is situated 

 about five miles west of Kongsvold. Amongst the rarer 

 specimens that may be found here are Grimmia apicu- 

 lata (a Poa having much in common with Poa dis- 

 tichophylla}, Poa flexuoso, minor, and ablreviata, and 

 a variety of Carex saxatilis. But, as just said, explo- 

 rations on the eastern side will be far more remumera- 

 tive. And first, there is a little valley called Spraen- 

 bsekdal. It is best to follow the course of the stream 

 till after passing the willow-limit, and then to steer 

 in a northerly direction up towards the Knudshoe 

 heights.
