The Flora of Disko Island and Adjacent (]oa.st of West Greenland. 37 



« 



Mainland: From the tracts of Holsteinsborg to the icefjord of Jakobshavn 

 rather common. especially at some distance from the outcoast (P.). Becoming- rarer 

 northwards; Ritenl)enk (Bg.); Påkitsoq-fjord (V; Bg. ; P.); Atanikerdluk (Htz.); 

 Xugssuaq (P.). 



A southei'ii type with hitlierto kiiown nortli limit on Schades 

 Øer 71°22' (P.). 



Often forming carpets recognizable at a distance by the green 

 colour and without admixture of other species. 



Abiindantly flowering and fruiting. 



Hibernates covered by snow and often by ice. 



A 37. Calamogrostis Langsdorfii (Likk.) Trin. 



On favourably exposed, moist hill-slopes, along rivulets and espe- 

 cially at the edge of thickets. 



Disko: Very rare; at Godhavn 6!)"15' (R. Br. Wetherill, not re-found by us: 

 perhaps extinct owing to the felling of willov^'s; near Skansen (Rikli!), and in thf 

 valley of Kugssuaq 69°30', within this locality (L. Geissler). 



Mainland: Qeqertaq 70°, seen in the houses of the natives used as boot- 

 straw (P.); Påkitsoq-fjord several localities (V.; P.); Egedesminde 68°40' (P.). 



From here southwards becoming common in the fjords and the valleys of 

 the larger Islands; in the interior around of N. Strømfjord very common (P. &R.), 

 as well as in the fjords inland from Holsteinsborg (P. & E.). 



A decided southern type having its northern limit at 70°. 



As a rule forming extensive dense carpets. Because of the length, 

 the delicacy and the toughness of the straw highly valued as boot- 

 straw by the natives, being the best material for this purpose. From 

 Egedesminde southwards often used for the making of domestic indu- 

 strial objects, for instance trays, baskets and caps. 



All the above mentioned localities are in the lowland. 



Abundantly flowering and fruiting; at the northernmost localities 

 not annually getting ripe. 



Hibernates covered by thick layers of snow. 



J. 38. Deschampsia flexuosa (L.) Trin vai. montana (L.) Hartm. 



Very rare, not common till the southmost part of Greenland 60° 

 -61° (Ros.j. 



In the area found at Itivneq 66°58' (W & H.); besides recorded by Sørensen 

 from Godhavn 69°15'. Determined by L. K. Rosenvinge and approved by Gelert 

 in Fl. Arctica, but the specimen may not originate from Godhavn. The only member 

 of the genus, which I have found at Godhavn after a search extending through 

 inany years, is a form belonging to the following species. 



A pronounced southern type.
