S. GLATJCA, L.; ft Lapponum (Fl. D. tab. 1,058) ; y appendi- 

 culata (PL D. tab. 1,056) ; 8 denudata. Grow over the whole 

 Fjeld, under very different forms. They mount up towards the 

 permanent snow in company with S. lanata, S. limosa, &c., but 

 not quite so high as S. herbacea and S. polaris. The capsules 

 are always covered with a thick white, or greyish-white wool 

 (according to age). The catkins of the male and female vary in 

 length, as also do the leaves, both in respect to colour, surface, 

 and margin ; but generally they are entire, and of a darker 

 colour on the upper than on the under side. 



S. LANATA, L. ; FL D. tab. 1,057. Found over the whole 

 Fjeld, at the same altitude as the last. The catkins of the female 

 are sometimes two to three inches long. Leaves generally broader, 

 and of more uniform colour on both sides, than in the last. Pro- 

 fessor Blytt found on Blaahoe a creeping willow scarcely one foot 

 high, in company with S. polaris. The leaves were more ellip- 

 tical, and nearly smooth, catkins shorter, and naked scales, bear- 

 ing a striking resemblance to specimens found in Greenland. 

 " Unfortunately," he writes, " I found but one fruit-bearing spe- 

 cimen of this apparently very early flowering form." 



S. HASTATA, L. ; Fl. D. tab. 1,238. Common over the whole 

 Fjeld ; extends far above the birch-limit. The form of leaves is 

 very variable sometimes elliptical, lanceolate, or oval. The 

 colour generally constant, dark on the surface, and a pale green 

 below. The plant varies much in size. As a creeping bush it 

 approximates to S. Arbuscula, but differs from it in the smooth- 

 ness of the capsules. 



S. ARBUSCULA, Fries. In places abundant. At Bergsgaard, 

 above Tofte, between Dombaas and Fogstuen, Jerkin, and Kongs- 

 vold, it is found above the birch-limit. 



S. PHYLICIFOLIA, L. (Fl. D. tab. 1,052) ; ft nigricans (Fl. D. 

 tab. 1,053) ; y majcdis. Besides these varieties a great many 

 intermediate forms are found over the whole Fjeld. S. phylici- 

 folia is found up to the birch-limit, ft nigricans grows as a 

 small tree near Fogstuen, and is found up to the limits of the 

 larger species, S. lanata, limosa, &c. 



S. CAPRCEA, L. ; FL D. tab. 245. Disappears below Tofte. 



S. DEFRESSA, L. On dry sandy places, near Tofte and Jerkin, 

 but not above the birch-limit. 



S. LIMOSA, Wahl. Grows at same altitude as S. lanata, &c.
