The Flora of Disko Island and Adjacent Coast of West Greenland. 33 



Sometimes it occurs in piaces that are inundated in the spring- 

 and early summer. In these piaces it develops long floating leaves 

 and rescmbles the following species. 



Diiring wet summers, when the pools do not dry up, it does not 

 flower, thus difTering from the following one. 



Because of its vegetative luxuriance in manured plåces it is par- 

 ticularly adapted to fodder for sheep and goats, both as green fodder 

 and as hay, and perhaps it may prove itself a valuable fodder-plant in 

 subalpine regions. But there is an inconvenience by the hay-making: 

 the plant forms big semispherical tufts which render the mowing with 

 scythe difficult. The green turfs formed by its web of roots are very 

 compact, hence preferred by the natives for house-building 



Very common on Disko and the Mainland around Disko-Bay; 

 also common in the archipelago of Egedesminde district and south- 

 wards along the coast down to Holsteinsborg. 



Still frequently to be found at the tent piaces in the fjords, but 

 else very rare here or quite absent. 



Possibly it may be found isolated in alpine habitats; we did not 

 find it during any of our excursions on tho hills although we searched 

 for it. 



In N. Strømfjord it was very common on the islet Taseralik at 

 the mouth of the fjord, where yearly 3 — 400 men and women meet; 

 at the tent- and fishing-place Eqaluarssuit it was found in great abun- 

 dance, but locally; but not at any of the tentplaces within that, 

 not even in the hills. 



In the region of Holsteinsborg it has been found a few times in the 

 vicinity of Amerdloq-Fjord down to 66°45' and for the present this 

 place must be etablished as the south limit of its continual distribution. 

 It has been recorded isolated from the head of Kangerdluarssuk-Fjord 

 at Frederikshaab by Th. Holm (Englers Jahrbiicher VIII, p. 200), 

 but the specimen does not exist. Mistake of identity is excluded; per- 

 haps it was alpine here, but this is not recorded by the collector. 



Northern type; in East Greenland known to ca. 68°, but does 

 not occur on Iceland (yet in Scottish mountains). 



Ascends, following the bog-formation, to the snow-line. 



Abundantly flowering and fruiting, 



Hibernates covered by snow. 



A 31. Alopecurus aristulatus Michx. 



Rooted in small ponds and on lake-shores with floating leaves and 

 stalks. During exceptionally dry summers to be found trailing on the
