PHYSICAL GEOGRAPHY 301 



officinalis, Vicia sepium, Galeopsis Tetrahit and Sangnisorba offtcinalis 

 occur only in southern and south-western Iceland. Anthyllis vnlneraria 

 is fairly common in south-west Iceland, but has otherwise been found 

 only in one place in East Iceland (Njardvik); Cakile maritima is 

 common in the sea-sand in south-west Iceland and in the southern 

 part of the north-western peninsula, but has not been found else- 

 where. Lathy r us palnster, L. pratensis and Veronica anagallis have 

 been found only in south-west Iceland, and Haloscias scoticum, also, 

 does not grow in other places with the exception of the islands in 

 Breidifjordur where it occurs rather frequently, and on the islands 

 in Horna fjord; Hydrocotyle vulgaris occurs near hot springs in South 

 Iceland, especially in the district of Borgarfjord, but has not been 

 found elsewhere; Zoster a marina is very common in south-west 

 Iceland, but is rare in other places. 



The plant life of the north-western peninsula is as a rule poor 

 in species and not very characteristic. Frag aria vesca has not been 

 found there, although it is fairly common all over the island; Cor- 

 nus suecica grows in some places in Vestfirdir and near Breidifjor- 

 dur. but has not been found elsewhere, and Melampyrum silvaticnm 

 has been found only in wooded valleys near Isafjord. Papaver nn- 

 dicaule appears to be more common on the north-western penin- 

 sula than in other parts of the island. In North Iceland only a 

 few characteristic plants occur. Pleurogyne rotata is, however, very 

 common in North Iceland, but rather rare in other places; Milium 

 effusnm also is especially characteristic of the northern districts. 

 Phyllodoce coerulea, which is so common in Greenland, is also fairly 

 common on the northern mountainous peninsulas on either side of 

 Eyjafjordur westwards as far as Fljot, but has not been found else- 

 where; Primula stricta has been found only near Eyjafjordur, and 

 Antennaria alpina and Erigeron nniflorns have been found only on 

 mountains in North Iceland. 



Moreover, it may be mentioned that, here and there, a few 

 otherwise rather rare species, by occurring in great abundance in 

 certain localities, give a characteristic appearance to the landscape. 

 Thus, in Selvogur Anthyllis vnlneraria occurs so abundantly that 

 during the flowering period large tracts are quite yellow; in Eyja- 

 fjordur and in Hrappsey considerable areas are closely covered with 

 Viola tricolor. In Trostansfjordur the whole strand is densely over- 

 grown with Cakile maritima, which, although rather common in 

 western Iceland, occurs nowhere so abundantly as here. An
