I. Introduction. 



THE Danish Jubilee Expedition to North-Western and Northern 

 Greenland in the years 1920 — 22 made botanical collections onlv 

 in North-Western Greenland. During the year 1921 Mr. J. Noe Nygaard 

 who was in charge of a party intended to bring provisions to the main 

 party under Mr. Lauge Koch on its return to the west coast, made 

 elaborate collections on different piaces from the southern part of Wash- 

 ington Land (ca. 80° N. Lat.) southwards as far as Mac Cormick Bay 

 in Murchison Sound (77°40' N. Lat.). Mr. Nygaard visited Washington 

 Land in the spring only and did not bring many piants back from this 

 area; on the other hånd he stayed for a longer time in Inglefield Land 

 and used this opportunity to collect an ample amount of dried piants 

 from difYerent localities there. Later he collected a very valuable mate- 

 rial in the Murchison Sound area around the Expedition base at Igdlo- 

 (^ luarsuit and at Neke and lastly some piants in winter stage from Pite- 

 q1^ ravik. His whole collection is unusually rich in specimens which makes 

 *"" it very valuable for studying the range of variation of the species. It 

 seems to me, that it must be considered rather complete as far as the 

 ^ more conspicuous species are concerned. But on the other hånd I think 

 <i; that a trained botanist still may be able to add some more species to 

 the flora of the region in question. 



Besides Mr. Nygaard's collection the leader of the Expedition 

 Mr. Lauge Koch collected a small number of piants ■ — some very 

 interesting — , when he reached the southern corner of Washington 

 Land after his traverse of the Inland-ice. 



It has been a very paying task to name the piants of these collec- 

 tions ; we have now — when we add these new records to those already 

 existing — a fair knowledge of the flora of this part of North-Western 

 Greenland. 



The many older statements from this region are treated off by 

 H. G. SiMMONS in his valuable paper on the flora of North-Western 

 Greenland (1909). Since then there are only few contributions to add, 

 namely some records in a plant-list based upon the Peary Expeditions 

 and published by P. A. Rydberg (1911 — 12), and the two small lists
