ALPINE FLORA AND FERNS OF NORWAY. 277 



the whole Fjeld in Alpine Flora ; nearly all the Alpine Flora of 



the north seems to have concentrated itself in this valley." There 



is good fishing in the Driv. Good quarters. 



The " birch-limit," under lat. 61, is 3,750 feet above the sea ; 



under 62 it is 3,700 feet above the sea. " The dwarf birch 



(lld'tla nana) grows everywhere in the Alpine regions, and at 



higher altitudes than any other of the tribe." UK SCHUBELEB. 

 The limit of eternal snow under lat. 62 is about 5,500 feet 



above the sea. That of the larger willows, e.g., Salix lanata, 



limosa, glauca, &c., under the same latitude, is about 5,000 feet. 



Whenever "corn-limit" is used the limit of barley is to be 



understood. 



ANEMONE VERNALIS, L. ; Fl. D. tab. 29. Common over the 



whole Fjeld. At Storhoc above Toi'te, and near Drivstuen, it 



reaches the limit of eternal snow. 



RANUNCULUS BEPTANS, L. ; Fl. D. tab. 108. Common up to 



and a little beyond the birch-limit, by Fogstuen ; near Kongsvold, 



it apparently vanishes at the above limit. 



Kongsvold is an excellent station for the botanist good 



quarters. The station is over 3,000 feet above the sea. Good 



shooting and fishing here. 



R. PLATANIKOLIUS, Fl. D. tab. 3. Rather common in Driv- 



dalen. On the heights by Drivstuen it is found up to the birch- 

 limit. 



R. GLACIALIS, Fl. D. tab. 19. Varieties of this plant, with 

 snow-white, light or dark rose-coloured flowers, are abundant on 

 the edges of melting glaciers. It appears to be the advanced 

 guard of the flower world towards the regions, of eternal snow. 

 Reindeer are extremely partial to it. The peasants call it the 

 rein-flower ; and wherever the sportsman finds this plant in great 

 quantities untouched, he may feel sure of not finding deer. In 

 places e.g., near Kongsvold it is found below the birch-limit. 



R. NIVALIS, Fl. D. tab. 1,699. Is found scattered about near 

 the highest parts of Vaarstien, on ascending the Fjeld from the 

 right. On the road from Vaarstien to Knudshoe, and on this 

 Fji-ld, it is general. It is found in large quantities on the heights 

 near to where the snow never melts, usually in company with 

 the Phipptiia <t/f/i<l<t, ,SV/.c//'my< oppoeittfolia, !>raba alpina, &c., 

 and reaches even higher than S. glacialis. Its flowers are bright 

 yellow ; and, where they are found in large quantities, as above
