The Flora ol' Disko Island and Adjacent Coast of West Greenland. 65 



A decided southern type, on the mainland from a few piaces 

 in Godthaab-fjord till 64''30' and not very common at 60° — 62' 

 according to Rosenvingp:. 



All the mentioned places are in the lowland. 



At Godhavn usually not flowering, only d uring favourable, i. e. 

 damp and moist summers, but then abundantly. 



We found unripened fruits in August 1917. 



Under a thick cover of snow in the winter. 



± I 14. Corallorrhiza trifida (L) Chatel. (C. innata R. Br.). 

 In vigorous herb-mats and near hot springs. 



Disko: Engelskmandens Havn 69°16' (Sør.) 1891, not re-found; in Disko- 

 fjord at Kuånerssuit (Th. Fr.). 



A decided southern type. On the mainland known from N. 

 Isortoq 67°15' (V.); southwards not till Godthaab-fjord. 



The above-mentioned specimens from Engelskmandens Havn are 

 flowering. 



Covered by snow in winter. 



Dicotvledones. 



XV. Salicaceae. 



i 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. 



± 116. Salix Myrsinites L. var. parvifolia And. 



S. ivigUitiana Lundstr., ^S". Uva Ursi Pursh sec. Schneider. 



Recorded from Ritenbenk 69°45' (V.) and from Jakobshavn 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.
