The Flora of Disko Island and Adjacent Coast of West Greenland, ^ 149 



Dis ko: North-east coast, rather common down to about 70° (P.). — Hare (P). 

 Mai ni and: Coast of Nugssuaq peninsula towards the Waygat rather common 

 from 70° to 70°45' (P.). Holsteinsborg 66°55' (alpine?) (Htz. affirm. Vierh.). 



Ahigh-arctic type, without northern limit, the above mentioned 

 localities are the southern limit of the species in West Greenland. 



Flowers earlier than the preceding and fructificates abundantly. 



Only covered by scanty layers of snow and perhaps sometimes 

 snowbare in winter. 



Where this and the preceding species are found together, e. g. on 

 the coasts of Waygat, the differences in the colouring in the live state 

 are very conspicuous. 



A 269. Erigeron uniflorus L. emend. Vierh. 



{E. alpimis var. leucocephalus, Lange). 



When we made our collections, we had no access to the work of 

 ViERHAppER and no clear knowledge of this species and its distribution. 

 Therefore some of our field notes from the southern parts of our area, 

 referred to E. unalaschkensis, may perhaps belong to E. uniflorus. 

 The species is in Greenland, according to the determinations of Vierhap- 

 per, a distinct southern type, rather common from the fjords at 

 64° and southwards. North hereof it has been collected at Qåumarnit 

 Qingua, 65°12' (Jens.), S. Isortoq, 65°20' (Ros.) Kangerdluarssugssuaq, 

 66°17' (Jens.), and once in Nordre Strømfjord, probably Ungoriarfik, 

 67°42' (Korn.). The last mentioned locality is the northern limit and the 

 only one lying within our area. 



The specimens in H. H. are flowering and fructificating. 



Without doubt covered by snow during winter. 



A 270. Erigeron (Trimorpha) borealis (Vierh.) Simmons. 

 {E. alpinus Lange p. p. E. neglectus Auctt. non Kern. 

 E. alpinus f. fastigiatus Ros.). 



According to the determinations of Vierhapper, also this species 

 is a distinct southern type with a still more southerly distribution 

 than the preceding. Its main occurrence in West Greenland is south of 

 the 62° parallel. A few specimens are collected in the fjords at 64°, 

 north hereof one specimen from Qåumarnit, 65°12' (S. H.) and another 

 damaged specimen, which cannot be determined with certainty, from 

 N. Isortoq, 67°10' (V.). If this specimen were right, it would 

 range within our area. 



Several times piants such as "E. alpinus" or '"E. neglectus" have 

 been reported from our area, up to 69°30' on Disko, but according to
