Material from Greenland, Iceland and the extreme north of 
Scandinavia. 
A prostrate, creeping dwarf shrub; the out-spread and 
prostrate branches all occur above ground, but often in the 
Fig. 25. Arctostaphylos Uva-ursi. 
A, B, F, G, H From Denmark; C from West Greenland; D, E from Iceland. A, Shews the 
relative position of the buds and of the leaves. B, An inflorescence (July 21). €, Flowering 
branch (almost natural size). D, A young inflorescence, and a vegetative bud. Z, A 
flowering branch with buds in the act of expanding (June 3); HK, the primary bud; 
1 to 5, the leaves. F, A seedling (1/1) with cotyledon (@) and primary leaf (A). (E. W.) 
course of time the older ones become covered with soil and 
plant-remains. The last of the year’s shoots curve slightly 
upwards, but afterwards become more horizontal (plagiotropic). 
The plant has a centrifugal growth. The younger branches are 
only sparingly furnished with adventitious roots; but these are 
more abundant upon the older ones especially those covered 
with soil, and one plant may break up into a number of inde- 
pendent plants. The leaves are more or less vertical (Fig. 25 
A, C, E), and remain green upon the stems from two to three 
years.
