T 42. Dupontia Fisheri H. Br. 



In moist iiiarsh-land and meadows or siibnierse in shallow pools 

 and lagoons. 



A pronounced hi gh- ar c ti c plant with sonthniost occurrence in 

 the northern part. of the area. 



Disko: On the northland IVom several loralities between Qutdligssat at the 

 Waygat about 70° and the head of Nordfjord and the valleys herefrom (P.). 



Main land: The coast of Nugssuaq from 70°15' to the mouth of the great 

 river, about 7n°30' (P.). 



In the localities, from which 1 have observed this plant, as well 

 within the area as farther northwards, it was growing near the shore; 

 a single exception is the great valley of Nordfjord where it grows on 

 newly raised fjord-bottom. 



Therefore I am inclined to consider the plant as halophilous. 



Hence all the localities in the lowland. 



Occurs forming widely extended carpets almost free from other 

 species and easily recognizable by the striking red-brown colour. In 

 water of some depth the whole carpet is ordinarily sterile, but near the 

 shore and on dryer ground it is abundantly flowering and fruiting. 



During winter covered by snow and, as a rule, also by ice. 



I 43. Phippsia algida (Sol.) R. Br. 



In moist localities among other Gramineae, in heath and bogs, in 

 manured soil near the houses and the deserted settlements, at pools, on 

 fowling islands and in the hills at the border of the melting snow-fields. 



Very common throughout the whole area, in the southern part 

 however, confined to the belt of rocks and islands girding the coast; 

 or in the mountain region of the interior, the ground of the lowland 

 here being occupied by competitors. 



At the settlements it has found its way, moreover, to the Danish 

 gardens and together with Stellaria media it has become a trouble-some 

 weed in the hotbeds. Here it develops to a phantastic size compared with 

 its appearance in nature. 



A widely distributed arctic plant, in Greenland without neither 

 northern nor southern limit, decreasing however, in frequency south- 

 wards, rather a northern type. 



i 44. Poa pratensis L. 



In nearly every kind of soil from the coast up to considerable 

 altitudes. On luxuriant slopes and on bushland very vigorous and often 

 forming dense extensive associations. Near new settlements it conquers
