The Flora of Disko Island and Adjacent Coast of West Greenland. 41 



P. alpina often characterizes rather large areas, but it never form& 

 dense associations. 



On favourable spots, ascending the slopes to considerable altitudes. 



Abundantly flowering and fruiting. Viviparons specimens have 

 never been seen by us. 



Snow-covered during winter. 



J. 47. Poa laxa Haenke. 



In Fl. Arct. Gelert states the distribution of this species as lying between 

 60° and 70°! ; the sign of ! indicates that he has seen and approved the determination 

 of the specimens from within these limits. But in H. H., revised by Gelert, I did 

 not in 1910 lind any specimens gathered from localities north of GCSS'. I have vari- 

 ous specimens myself from the coasts of Disko and Nugssuaq corresponding fairly 

 well with the diagnosis of P. laxa. but owing to the lack of figures and exactly 

 determined Greenlandic material of P. laxiuscula Lange I dåre not quite trust these 

 determinations, the closely related P. glauca being so very much variable. 



A southern typo. 



Abundantly flowering and fruiting. 



Hibernates covered by snow. 



T 48. Poa abbreviata R. Br. 



On barren sand and gravel and newly formed moraine. A high- 

 arctic species found a few times in the northmost part of the area. 



Disko: The north-western coast: Igdlorpait 70°5' (Th. Fr.); the coast of Way- 

 gat: Kugånguaq 70°15' (Th. Fr. ; P.); Asuk 70°10' (Th. Fr. ; P.); Qutdligssat 70" 

 (Htz.). 



These localities represent the hnown southern limit in Greenland. 

 Here flowering and fruiting. 

 No doubt often snowless. 



I 49. Poa glauca M. Vakl. 



On fell-field; gravelly, sandy and stony soil, newly formed mo- 

 raine, sand-shores and dunes, but also to be found under better con- 

 ditions, for instance, in manured soil and thus frequent at the settle- 

 ments. Varies without limits according to the quality of the place. 

 Often forming extensive patches, especially when manured and irrigated 

 during the period of vegetation. Not well adapted to forage plant for 

 cattle, having only a few leaves and the straw being short, stiff and 

 too early ripening. 



Very common throughout the whole area. 



Widely distributed species without neither northern nor southern 

 limit in Greenland.
