The Flora of Disko Island and Adjacent Coast of West Greenland. __ 149 
Disko: North-east coast, rather common down to about 70° (P.). — Hare © (P). 
Mainland: Coast of Nugssuaq peninsula towards the Waygat rather common 
from 70° to 70°45’ (P.). Holsteinsborg 66°55’ (alpine?) (Htz. affirm. Vierh.). 
A high-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. Viern. 
(E. alpinus 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 £. uniflorus. 
The species is in Greenland, according to the determinations of VirrHAp- 
PER, a distinct southern type, rather common from the fjords at 
64° and southwards. North hereof it has been collected at Qaumarnit 
Qingua, 65°12’ (Jens.), S. Isortog, 65°20’ (Ros.) Kangerdluarssugssuaq, 
66°17’ (Jens.), and once in Nordre Stromfjord, 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 (Vieru.) Simmons. 
(E. alpinus LANGE p. p. E. neglectus Auctt. non KEern. 
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 Qaumarnit, 65°12’ (S. H.) and another 
damaged specimen, which cannot be determined with certainty, from 
N. Isortog, 67°10’ (V.). If this specimen were right, it would 
range within our area. 
Several times plants such as “E. alpinus” or “E. neglectus” have 
been reported from our area, up to 69°30’ on Disko, but aceording to
