DURING the first Thule-Expedition (1912) Mr. Peter Freuchen 

 collected a fair number of plants at several of the tent-places of the 

 expedition. It is quite remarkable that he succeeded in making botanical 

 collections under the circumstances under which he worked, and in 

 bringing the plants collected home in good condition. 



His time for collecting was very restricted, and we may therefore 

 not expect that the list given below comprises the entire flora. It is 

 merely a list of the more conspicuous flowering herbs and shrubs, while 

 such plants as grasses and sedges naturally have been neglected, at 

 least in part. Of course also the cryptogames are very poorly repre- 

 sented in the collection; some few tufts of mosses and single pieces of 

 lichens and algse are brought home, and in the moss-tufts and among 

 the basal parts of the flowering plants several other mosses have been 

 discovered, when I was working up the collection. Mr. A. Hesselbo 

 has been good enough to prepare a list of the mosses, while I have thought 

 it of no importance to try to get names to the few pieces of algse and 

 lichens which are only very commonly distributed arctic forms. 



In 1909 Dr. H. G. Simmons pubhshed "A revised hst of the 

 Flowering Plants and Ferns of North Western Greenland" (Rep. Sec. 

 Norweg. Arct. Exped. in the "Fram" 1898—1902, No. 16), in which 

 he has critically compiled all earlier contributions to the flora of N. W. 

 Greenland north of Melville Bay. If we compare his list with that given 

 below, we will find no species enumerated here which has not been found 

 before in N. W. Greenland. On the other hand, our list is very useful 

 with regard to the regional distribution within this big area, extending 

 from ca. 76° Lat. N. to nearly 84° Lat. N., as it brings the records of 

 several species much farther north than hitherto. N. W. Greenland 

 may, from a botanical point of view, be divided into two natural parts, 

 a northern part north of the big Humbolt Glacier, and a sounthern 

 part south of it. The southern part is much richer in plants — is 

 also better explored, botanically, — than the northern one. Simmons 

 (I. c, p. 22) gives only 27 species known from the northern part, while 

 the flora of the whole N. W. Greenland contains 108 species, and all 

 of the 27 species of the northern part (except one: Diipontia Fiskeri, 

 which occurs farther south in Greenland) are also found in the southern 

 part.
