The Flora of Disko Island and Adjacent Coast of West Greenland. 65 
A decided southern type, on the mainland from a few places 
in Godthaab-fjord till 64°30° and not very common at 60° 62° 
according to ROSENVINGE. 
All the mentioned places are in the lowland. 
At Godhavyn usually not flowering, only during favourable, i. e. 
damp and moist summers, but then abundantly. 
We found unripened fruits in August 1917. 
Under a thiek cover of snow in the winter. 
i 114. Corallorrhiza trifida (L.) Cuarec. (C. innata R. Br.). 
In vigorous herb-mats and near hot springs. 
Disko: Engelskmandens Havn 69°15’ (Sor.) 1891, not re-found; in Disko- 
fjord at Kudanerssuit (Th. Fr.). 
A decided southern type. On the mainland known from N. 
Isortog 67°15’ (V.); southwards not till Godthaab-fjord. 
The above-mentioned specimens from Engelskmandens Havn are 
flowering. 
Covered by snow in winter. 
Dicotyledones. 
XV. Salicaceae. 
115. Salix herbacea L. 
In bogs and moist spots in the heath, among stones in the outlets 
of springs; very typical for places where the snow-cover lasts long. 
Very common throughout the whole area. 
Widely distributed in West Greenland without south limit; the 
north limit is unknown, no doubt to be found north of 76°. 
Ascending the hills to considerable altitudes, though not in newly 
formed mineral soil. 
Abundantly flowering and fruiting. 
Hibernates covered by a thick layer of snow and often besides 
by ice. 
1E 116. Salix Myrsinites L. var. parvifolia Anp. 
S. trigtutiana Lunpstr., S. Uva Ursi Pursu sec. SCHNEIDER. 
Recorded from Ritenbenk 69°45’ (V.) and from Jakobshayn 69°13’ (V.). 
A decided southern type; not known till 64°48’ in the Godthaabs- 
fjord; and it is possible that the above-mentioned specimens may prove 
themselves to be something else, for instance, a hybrid between the 
other species.
