Obs. A few of the spccinions were determined by H. Dahlstedt. 



North of our aroa known to at least 12° b' (Ryder), south of 66°45' 

 no findinijs are roportcd till aii isolated one at 61°, Not observed in 

 Easf Greenland. 



In accordance wilh tlie range of the species in Greenland und Arc- 

 tic America (see Dahlstedt) probably a northern type. 



Abundantly llowering and fructificating. 



Covered by snow during ^^^nter. 



T 281. Taraxacum arctogenum Dahlst 1. c. p. 27. tab. 16. 



A high-arctic type, occurring north of 76°, only once observed 

 in our area on an islet in Sydost Bugt, 68°35' (Htz. det. H. Dahlstedt). 



A 282. Taraxacum croceum Dahlst. coll. 



Confer. H. Dahlstedt: Om skandinaviska Taraxacumformer. Bot. 



Not. 1905. idem: Nordsvenska Taraxaca. Ark. f. Bot. 12. N. 2. 1912. 



For the present I thus denote the most common species of Taraxa- 

 cum in our area. They occur on favourable, sheltered spots, common in 

 the Southern parts of the area and, for instance on the southern half 

 of Disko, but scarce or absent on the northern. Thus their occurrence 

 corresponds to that of the southern types. The northernmost point, 

 where I have seen a representative of this group, is on the south coast 

 of Svartenhuk peninsula 71°25' (P.). 



In our area at least two species occur, one more common ^^^th pale 

 flowers and a rarer one with larger and darker heads. The last mentioned 

 seems to be restricted to the most favourable situations in the south- 

 most parts of the area and on South Disko. I have not tried to identify 

 them with some of the species of the group provisionally described by 

 Dahlstedt in Bot. Not., but they seem to me to be related to Dahl- 

 stedt's N. 2: spectahile and N. 3: croceum, which, according to the 

 author, are known to him from Greenland. 



Abundantly flowering and fructificating. 



Covered by thick layers of snow^ during winter. 



J. 283. Hieracium hyparcticum Almq. 



In luxuriant herb-mats and willow-t liickets. 



Mainland: Only observed in the southern parts of our area: N. Isortoq, 

 67°15' (Ros.); S. Kangerdluarssuk, 67^ (Ros.); Holsteinsborg, Præstefjæld, 66°55' 

 (several coiiectors) all determined by H. Dahlstkdt. Naujarssuit in QeqertaJik- 

 fjord, 66°45' (P. & E.) det. by C. H. Osten fem.. 



A distinct southern type, soutli ol thr area known to 60°. The 

 above mentioned localities are the northern limit.
