Sometimes, however, the hairs on the inside of the corolla, 
especially those at the throat, occur rather sparingly. 
Cross-pollination by insects may easily take place. Honey 
is secreted by a hypogynous disk of ten glands (Fig. 21 @). 
The capsule is erect. Poprrus observed Colias Paleno L., 
Plusia microgamma Hb. and Bombus agrorum Fabr. visiting 
the flowers. 
The flower is obdiplostemonous, and the carpels are anti- 
petalous. I have found 4-merous flowers in Finmarken and in 
Greenland. 
I do not find any important difference between Greenland 
and European individuals.

Material from Finland (flowering in the Botanie Garden in 
Gopenhagen). 
A low, erect shrub. The coriaceous leaves remain for 
more than a year on the branches, and turn reddish in colour 
in the autumn. The buds, which are protected by scale-leaves 
are still small even in autumn. 
The flowers, which are white, occur singly in the axils of 
the upper leaves, and are drooping. Towards the apex of the 
shoots they rather cluster together, and the subtending leaves 
becoming smaller they approximately form a racemose inflores- 
cence. Two ovate-acute bracteoles occur immediately below 
the calyx of the flower (Fig. 22 C). 
After flowering, the whole of the floral portion of the shoot. 
i. e. about one third to one half of the whole of the years 
shoot, dies, and then just below it long shoots, from one to 
several, all similar in appearance, are developed while the lower 
part of the shoot remains branchless. 
The corolla is cylindrical-urceolate, about 7 mm. long; and
