The Flora of Disko Island and Adjacent Coast of West Greenland. 147 
Abundantly flowering and fructificating. Probably always covered 
by some snow during winter. 
Varying in size, broadness of leaves etc. according to the conditions 
of the habitat. 
i 265. Campanula rotundifolia L. 
On similar spots as the preceding, but much more common. 
Widely distributed in West Greenland, without southern limit, 
the northern limit may lie between 74° and 76°. 
Abundantly flowering and fructificating. Probably always covered 
by some snow during winter. 
Varying very much. Whether the Greenlandic cycle of forms of 
the collective species C. rotundifolia deserve to be united under a spe- 
cial name, С. Gieseckeana (Vest.) Witas., I cannot say. On the other 
hand I am inclined to suppose that the different varieties recorded from 
Greenland and provided with names are merely ecological forms, con- 
nected through numerous transitions. The variety arctica of LANGE 
is the normal form, occurring on somewhat favourable spots in our 
area. On exposed spots the plants are smaller, especially lower, whe- 
reas the corolla is as large or even larger, than on the luxuriant form 
from rock-shelves. On the most barren spots we find a low form also 
with small flowers: var. uniflora LANGE. 
XLVII. Compositae. 
V 266. Erigeron compositus Pursu. 
On gravelly moraines and barrens, in sandy river-beds and deltas, 
descended from the highland. 
Disko: The northern part of the Waygat coast, common (P.), in the big valleys 
and on the basaltic plateaus on the Northland (P.), Mellemfjord (Th. Fr.). — Hare 
(2) (18%) 
Mainland: Nügssuaq peninsula, common in the basaltic and sandstone area, 
as well near the coast as on the hills and in the big valleys (P.). South hereof not 
found till Claushavn, 69°5’ (Bg.), Nordre Stromfjord at Eqaluarssuit, 67°36’ (P. & Е), 
N. Isortog (V.), Holsteinsborg district, near the colony and especially in the interior, 
where it becomes rather common (Р. & E.). 
Without doubt a northern type, probably without northern limit. 
South of our area observed in the fjord-regions at 64° and 60°— 61°, 
probably here descended from the highland. 
Abundantly flowering and fructificating. 
Often snowless in winter.
