the position of the pores, and may occur more easily in pumi- 
lum than in the form from Central Europe; but the Greenland 
flower is evidently adapted also for pollination by insects. Honey 
is secreted by the thick, lobed disk at the base of the style 
(Fig. 33 @). The style and the stamens are often placed near 
to the upper side of the corolla. Lısoman has seen specimens 
in which the stamens had been bitten off by insects (Dovre). 
Exsram and O. Saxresson saw Bombus visit the flower. 
The plant sets fruit in West Greenland (Exsram records : — 
“Epizoische Samenverbreitung” “durch beerenfressende Vögel” 
in Nova Zembla).

Observations from Norway (Finmark) and Denmark. 
A creeping dwarf shrub; the prostrate, rooting stems which 
occur above ground, are very slender and delicate, and have 
elongated internodes (Fig. 35); the roots, which arise from above 
the axillary buds, are hair-like and branch fairly abundantly 
(Fig. 35 K). 
The foliage-leaves remain green on the stems about two 
years; their under sides are covered with a very glaucous layer 
of wax. 
The buds are protected by scale-leaves, and the lateral 
buds also by the somewhat erect, subtending petioles (Fig. 35 
F,@, H). Branches arise not only below the apex of the floral 
shoot (Fig. 35 B, D, E), but also occur scattered here and there 
lower down on the stem. The year’s growths have at their 
bases a few scale-leaves which are not close-set. 
The flowers are in a small inflorescence of from one to 
four flowers, at the apex of the leaf-bearing shoot. They are
