its glandular hairs closes on the ovary, which is also covered 

 with glandular hairs. 



The fruit, which is a septicidal capsule (Fig. 10 i^), ripens 

 both in West and East Greenland. It is seated upon an upright, 

 straight stalk. 



The carpels are antipetalous (Fig. 10 J) and the lobes of 

 the stigma antisepalous ; the arrangement of the parts of the 

 flower is the same as in the Ericaceae.

Material preserved in spirit, and observations from Green- 

 land and the north of Scandinavia. 



A creeping dwarf shrub vvith a strong primary root. The 

 prostrate, woody stems, which are often covered by moss and 

 soil, frequently give off many very slender, but much branched 

 roots. Hence it may spread over large patches of ground and 

 break up into independent plants. The stems branch sparingly, 

 generally with one to two branches from the upper part of the 

 year's shoots, especially when the latter produce flowers. But 

 owing to the shortness of the year's shoots numerous branches 

 often occur crowded together into dense cushions. 



The buds have no scale-leaves, but the year's shoots have 

 small foliage-leaves at their bases, the limits of each year's 

 growth are therefore not distinctly marked. 



The stems are slender (usually about 1 mm. thick), but 

 may attain to a thickness of 4 mm. The wood of an II -years- 

 old branch, according to Haglund, was only Г25 mm. in diameter, 

 its largest annual ring being 0"25 mm. 



The foliage-leaves are more or less erect (Figs. 13, 14); 

 they remain several years on the branches, but very possibly
