The Flora of Disko Island and Adjacent Coast 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; Ritenbenk (Bg.); Pakitsoq-fjord (V; Bg.; P.); Atanikerdluk (Htz.); 
Niigssuaq (P.). 
A southern type with hitherto known north limit on Schades 
Ber 71°22’ (P.). 
Often forming carpets recognizable at a distance by the green 
colour and without admixture of other species. 
Abundantly flowering and fruiting. 
Hibernates covered by snow and often by ice. 
A 37. Calamogrostis Langsdorfii |Link.) Trin. 
On favourably exposed, moist hill-slopes, along rivulets and espe- 
cially at the edge of thickets. 
Disko: Very rare; at Godhayn 69°15’ (R. Br. Wetherill, not re-found by us: 
perhaps extinct owing to the felling of willows; near Skansen (Rikli!), and in the 
valley of Kigssuaq 69°30’, within this locality (L. Geissler). 
Mainland: Qeqertaq 70°, seen in the houses of the natives used as boot- 
straw (P.); Pakitsoq-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. Stromfjord very common (P.&F.), 
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 domestie 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. 
1 38. Deschampsia flexuosa (L.) Trin var. montana (L.) HAartM. 
Very rare, not common till the southmost part of Greenland 60° 
— 61° (Ros.). 
In the area found at Itivneg 66°58’ (W. & H.); besides recorded by Sorensen 
from Godhavn 69°15’. Determined by L. K. Rosenvince and approved by GeLerr 
in Fl. Aretica, but the specimen may not originate from Godhavn. The only member 
of the genus, which | have found at Godhavn after a search extending through 
many years, is a form belonging to the following species. 
A pronounced southern type.
