The Flora of Disko Island and Adjacent Coast of West Greenland. 45 



One of the main-plants of the clay-plains in the interior, from the districts 

 of Holsteinsborg to Disko Bay. Besides from some localities on the shores of 

 Waygat. 



Probably a southern type in West Greenland. 

 Abundantly flowering and fructificating. 



1 57. Puccinellia tenella (Lange) Holmb. hoc loco! 



(Incl. Glijceria Langeana Berl.). 



In localities similar to those of the preceeding species, rarer or 

 overlooked because of its diminutiveness. 



No doiibt to be found in a great many piaces when only searched 

 for. 



Disko: In several piaces near Godhavn (P.). 

 Hare O (P.). 



Mainland: From several localities in the Sydostbugt (Htz.; P.); the archi- 

 pelago of Egedesminde: Kullen (K.); Kangåtsiaq (Bl.; K.); Augpilagtoq 68°44' (K.). 



Abundantly flowering and fruiting. 

 Hibernates covered by snow. 



i 58. Festuca ovina L. 



In all sorts of soil from the most barren gravel and sand, in cre- 

 vices between boulders and pebbles to heath, vigorous herb-mats, 

 thickets and manured piaces. 



Very common throughout the whole area. 



Being common in the littoral halophilous zone of the coast, it 

 ascends the hills to the snow-hne. 



Widely distributed in Greenland; if the rather much deviating 

 F. brevifolia R. Br. is to be reckoned as a form of F. ovina the species 

 has neither northern nor southern limit. Otherwise the northern limit 

 has to be searched for somewhere at the shores of Melville Bay. 



Very much variable, and numerous forms and varieties have been 

 described. To be sure most of them are dependent upon the quality of 

 the native place. I have not been able to ehcit whether hereditary 

 constant forms occur too or not. 



Abundantly flowering and fruiting. 



In many of the native piaces hibernating without cover of snow. 



A 59. Festuca rubra L. var. arenaria Osb. 



On fairly moist sand, for instance, along the shores of rivers and 

 lakes; among other Gramineae in heath; at the base of dunes and 

 often in manured soil or in thickets.
