Bb. lapponicus and B. scrimschiranus in the north of Sweden 
(SKOTTSBERG). 
But self-pollination also must easily take place as the 
flowers are drooping and the stigma consequently is below the 
anthers. That self-pollination takes place I conclude from the 
fact that in one of the distriets of Greenland (Godthaab), where 
it was still quite winterly and quantities of snow were lying on 
the ground, pollination had already taken place, although | 
never observed any insects visit the flower, either there or 
anywhere else in Greenland. 
The flowering period is very long; during the whole of the 
summer I spent in Greenland | found newly expanded flowers. 
Abundant fruit is set regularly in East and West Greenland 
and ripens the same year as that in which the plant flowers. 
The berry is globular, from 9 to 12 mm. in diameter.

Observations and material from Greenland, Norway (Fin- 
mark) and Sweden. 
A dwarf shrub with long, subterranean runners, which 
bear scale-leaves (Fig. 32) and live sometimes for more than a 
year beneath the surface of the soil, being seen to consist of 
older parts which are brown, and younger parts pale in colour. 
The runners have very slender, branching roots which are 
given off beyond the buds, from the axils of leaves (Fig. 34 F); 
they have a straight apex (Fig. 32).
