europa vol. V. 3, p. 1652, where he states the occurrence to be coin- 
cident with that of Trientalis europaea, for which a map is given in the 
same volume p. 1862. Northward, it stops where the forest stops and 
the tundra begins. At its northern limit it is a lowland plant, in Norway 
only ascending to low or moderate altitudes (NoRMAN), and only on 
the most favourable points it reaches high latitudes, f. inst., in Norway 
and in the Lena valley, up to 71° N. If, indeed, the climatic require- 
ments of the American and Eurasian stock of A. polifolia are different, 
a renewed investigation of their identity might be appropriate.’ The 
arctic Andromeda of America may, with the Greenland plant, constitute 
an undiscerned form, making Andromeda analogous to such species 
as Vaccinium Vitis Idea of which Greenland and America have only 
the variety pumilum, or of Saxifraga comosa, the nearest relative of 
which S. stellaris is in Europe and South Greenland, but not in America. 
For A. glaucophylla, FERNALD, l|.c., gives the distribution: Ailik 
Bay 55° N. in Labrador, west to Lake Winnipeg, south to Minnesota, 
Pennsylvania and Northern New Jersey. A remarkable extension is 
Southwest Greenland 62°20’—38’ N., but it has a great number of 
parallels, f. inst., Carex pratensis, Streptopus amplexifolius, Orchis ro- 
tundifolia, Anemone Richardsoni and some 30 others. It seems easiest 
to interpret the small and isolated Andromeda occurrences in Greenland 
as the dwindling remainder of a more genial postglacial optimum- 
climate when probably the areas were much larger. 
IV. 
THE GREENLAND CRANBERRY. 
In the southern part of West-Greenland, from the Godthaab Fiord 
region, in 64°32’ N., and down to the southernmost point, a cranberry 
is quite common. By J. VAHL, in his printed labels, and by Jon. LANGE, 
in his “Conspectus Fl. Grl.”, 1880, p. 90, it was simply called Oxycoccus 
palustris Pers., but A. BERLIN identified plants collected by himself as 
O. palustris *microcarpus Turcz., and claimed this subspecies to be new 
to the Greenland flora (Ofv. K. Vet. Ak. Férh. Stockholm 1884, Nr. 7,
