A prostrate dwarf slirub, with a strong primary root. The 

 long, prostrate shoots form adventitious roots, which may grow 

 very strong, and therefore the plant may produce off-shools, 

 which become detached from the parent and form independent 

 plants. The older branches are closely pressed to the ground, 

 and often more or less subterranean and hidden under decaying 

 leaves or other plants.

Fig, 23. Arctostaphylos cclpina. 



A, Terminal bud (Noi-way; Aug.). B, Young inflorescence (Finmark; July/, 1S85); all the 

 parts of the flower are formed, and are fairly large. 



The foliage-leaves turn deep red in autumn , and then 

 decay, but persist a very long time in the faded and decayed 

 condition until they crumble away. They have a peculiar silvery 

 lustre owing to the fact that the two lowest layers of cells, by 

 separating from the others, form a hollow space inside the leaf 

 filled with air. 



The buds are protected partly by the petioles which are 

 somewhat erect at the base and adpressed to the stem, and 

 partly by true scale-leaves (Fig. 23 Л). The terminal buds are 

 much larger than the others (Fig. 23 A].
