Under Mr. Larsen’s guidance we went straight to the plant. It 
grew between mosses — no Sphagnum — in company with Myrtillus 
uliginosa, Ledum decumbens, Betula nana, species of Carex and Juncus 
ete., on morainic soil. The island consists totally of gneiss and granite. 
The area occupied by the Andromeda was barely more than 50 m. 
across. It was in full flower, on Aug. 22nd, and we found a few fruits 
from the year before. 
In identifying plants from West Greenland it is quite appropriate 
to look up the status of the species in question in Northern Atlantic 
America. In regard to Andromeda, M. L. FERNALD has shown, (Rhodora 
1903, p. 67) that here are two species, viz., the common A. glaucophylla 
Link. and the much rarer A. polifolia, restricted to arctic-alpine situa- 
tions. For the history and nomenclature of A. glaucophylla see FER- 
NALD’S paper, as well as a later article by the same author in Rhodora 
1916, 100. Of the first species, I had a specimen from Nova Scotia (Gray 
Herbarium N. 24289, leg. M.L. Fernaıp and B. Lone.) showing a 
fruiting shrub 2—3 dm. high with leaves up to 33 mm. in length; thus, 
in habit and size very different from all the small Greenland specimens. 
As my partner on the trip, A. E. Porsitp, wanted to leave Greenland 
to go to America that autumn, I was forced to label our collections 
of the trip somewhat hurriedly, as he wished to compare some critical 
plants with the large collections in the Copenhagen herbarium. The 
Andromedas from both of the new localities were thus labelled “A. poli- 
folia L.” and duplicates with that name issued. At Copenhagen, however, 
A. E. Porsitp found ample material of A. glaucophylla, by which he 
could prove that the Andromedas from all the southern localities in 
Greenland really belonged to this species, whereas the specimens col- 
lected at Manitsoq, six degrees farther north, were A. polifolia L. After 
a renewed investigation of the specimens I quite agree with him. 
Before going into detail, I have still to mention that WARMING 
in his “Biology of Arctic Plants” (Medd. om Grl. 36, p. 29) studied the 
morphology and biology of the flowers of A. polifolia, chiefly on Danish 
and Norwegian material. He also mentions material from West Green- 
land, of which he says, in describing the flowers: 
“I do not find any important difference between Green- 
land and European individuals.” 
As the plants of Kornerup, at that time, were the only ones known, 
this statement must refer to those specimens, i. e. herbarium specimens 
with but few and quite young flowers.
