Pollen tetrads (Fig. 28 C) may be found scattered abundantly 
upon the style, and may also, though with great difficulty, find 
their way to the small stigma (Fig. 28 D) which is situated at, 
or immediately within, the throat of the corolla, sometimes 
however slightly beyond the latter. 
Honey is secreted abundantly and occurs in large drops 
on the disk. 
On the Dovre the flowers are visited by Bombus alpinus 
(Lixpmay), in Lapland by B. consobrinus, B. lapponicus and B. 
scrimshiranus (SKOTTSBERG). 
The flowers are often found split at the throat; they have 
been split by insects (Fig. 28 AK); and then the style is thrust 
far out. 
The form of the ovary varies (see figures, and SPRENGEL,

Material from Greenland, Iceland and Finmark. 
A dwarf bush with subterranean runners the apices of which 
are straight (Fig. 29 D); at the point where the runner rises 
above the soil in a curve, the scale-leaves merge by easy 
stages into foliage-leaves (Fig. 29 C). 
Very slender roots, which branch rather abundantly, arise 
from the leaf-axils above the axillary bud (Fig. 29 /). 
The foliage-leaves generally fall at the end of the season of 
growth, often turning red, but they may persist in a decaying and
