the position of tlie pores, and may occur more easily in pumi- 

 liim 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 G]. The style and the stamens are often placed near 

 to the upper side of the corolla. Lindman has seen specimens 

 in which the stamens had been bitten off by insects (Dovre). 

 Ekstam and 0. Santesson saw Bombus visit the flower. 



The plant sets fruit in West Greenland (Ekstam 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 Z). 



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, (r, H). Branches arise not only below the apex of the floral 

 shoot (Fig. 35 jB, Д Æ'), 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
