XXXV. Vacciniaceae. 
| 235. Myrtillus uliginosa (L.) Dres. var. microphylla Lance. 
On heath-land, cliffs and barrens. 
Very common throughout the area. 
The widest distributed shrub in Greenland, horizontally as well 
as vertically, without southern or northern limits. 
Abundantly flowering and fructificating. 
Often snow-less during winter. 
Locally, on favourable spots, especially on sunny rock-ledges or 
in clefts with sufficient moisture in summer, a stouter, tall-leaved form: 
var. pubescens (Horn) LANGE occurs. It is always covered by thick 
layers of snow in winter and late flowering, whereas var. microphyllum 
is early flowering (Conf. Porsttp: Medd. om Gronl. 50. p. 381 fig. 14 
and p. 362 fig. 9). Perhaps there is a certain connection between the 
late flowering and the snow covering. Another direct effeet may be 
that his form, at least in the northern parts of the area, but seldom 
or never fructificates. 
The berries of var. microphylla are very juicy and palatable and 
are much coveted by Europeans in Greenland. Also the natives do 
collect and eat them, but not to the same extent as those of Empetrum, 
principally because they ripen before the frosts set in and are impos- 
sible to keep in the natural state. 
A 236. Vaccinium Vitis Idaea L. var. minus Lopp. (Syn. 
vy. pumilum Hoxy). 
On luxuriant heath and not too wet mossbogs. 
Disko: Very rare, near Godhayn, 69°15’, on a single spot, hardly 10 m in dia- 
meter between Lyngmarken and Osterdal (E. P.). “Disko’’, special locality not 
mentioned, found by Margrete Krarup Smith, perhaps from the same spot. 
South coast at Igpik, 69°18 and Kugssuaq, 69°20’, on both places only a few speci- 
mens (P.). — Diskofjord, according to the natives the plant is said to grow somewhere 
near the mouth of the fjord, but nobody knows the locality now. 
Mainland: Jakobshavn, 69°13’ (Pfaff.). South of the Icefjord rather common, 
especially in the Sydostbugt (P.). Also common on the islands around and south 
of Egedesminde as well as in the fjords on those latitudes (P.). Very common in 
Nordre Stromfjord and in the fjords inland from Holsteinsborg (P. & E.). 
A southern type principally occurring in the middle parts of 
the west coast. In the southernmost parts of Greenland the occurrences 
are searce. North of our area the plant has several times been reported 
in the literature, right to 76°, but all the reperts want confirming and 
until then Disko has to be considered the northern limit. 
The var. minus Lodd. is at the same time a western type, widely
