S. erauca, L.; 8B Lapponuwm (FI. D. tab. 1,058); y appendi- 
culata (Fl. D. tab. 1,056); 6 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. nanaTA, 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 Blaahoé 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. gastaTa, 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. Arbuscwla, but differs from it in the smooth- 
ness of the capsules. 
S. ArpuscuLa, 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); B nigricans (FI. D. 
tab. 1,053); y majalis.—Besides these varieties a great many ~ 
intermediate forms are found over the whole Fjeld. S. phylici- 
folia is found up to the birch-limit. B nigricans grows asa 
small tree near Mogstwen, and is found up to the limits of the 
larger species, S. lanata, limosa, &c. 
5. capraa, L.; Fl. D. tab. 245.—Disappears below Tofte. 
S. DEPREsSA, 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.
