ALPINE FLORA AND FERNS OF NORWAY. 289 



found up to the continual snow. It has a very decided tendency 

 to vary. A variety with a long stalk and delicate leaves, 

 bearing a great similarity to S. HYPNOIDES, is found growing on 

 loose gravel near Blaahoe and other places. The little stunted 

 form which has been named S. grcenlandica is common on dry 

 places at high altitudes. 



S. CERNUA, L. ; Fl. D. tab. 22 and 399. From the limit of fir 

 up to the continual snow. It has, like the last, a great ten- 

 dency to vary ; sometimes being found more or less branched) 

 with a single terminal flower, or with more ; more or less hairy. 

 Flowers white. 



S. RIVULARIS, L. ; Fl. D. tab. 11. On high places on the 

 Fjeld, commonly by snow-water streams, fissures in the rock, 

 &c., up to the permanent snow. Scarcely found as low down as 

 the limit of fir. 



S. NIVALIS, L. ; Fl. D. tab. 28. In places over the whole 

 Fjeld, especially by Kongsvold and in Drivdal. Flowers, 7 to 8, 

 white or reddish. A variety, /3 tennis, is found near Fogstuen,
