Folien tetrads (Fig. 28 С) 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 Do vre the flowers are visited by Bombus alpmus 

 (Lindman), 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 iC); and then the style is thrust 

 far out. 



The form of the ovary varies (see figures, and Sprengel, 

 Entdeckter Geheimnis, tab. XXII, fig. 21. H. Müller, Befruchtung, 

 fig. 133, 1 ; Lindman 1. с).

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 E). 



The foliage-leaves generally fall at the end of the season of 

 growth, often turning red, but they may persist in a decaying and
