The Flora of Disko Island and Adjacent Coast of West Greenland. 59 
T 42. Dupontia Fisheri В. Br. 
In moist marsh-land and meadows or submerse in shallow pools 
and lagoons. 
A pronounced high-arctice plant with southmost occurrence in 
the northern part of the area. 
Disko: On the northland from several localities between Qutdligssat at the 
Waygat about 70° and the head of Nordfjord and the valleys herefrom (P.). 
Mainland: The coast of Nûgssuaq from 70°15’ to the mouth of the great 
river, about 70°30’ (P.). 
In the localities, from which I 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. 
| 43. Phippsia algida (Sor.) В. 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. 
Г 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
