often more or less dark-red in colour. Scale-leaves are absent, 

 but the branches bear, at first, entire foliage-leaves, and only- 

 higher up do the characteristic three points appear on the 

 leaves (Fig. 34C). In West Greenland, Va^höffes found a form 

 suhintegrifolia Abrom. il. c. PI. V. Fig. 3i of which almost all 

 the leaves were entire. 



The leaves are seated very closely together upon a long, 

 slender stem ; sometimes a shoot is developed which has longer 

 internodes.

The leaves remain green throughout one winter, but stay 

 upon the branches a long time after death, colourless or black 

 (Fig. Zi A. Bi. During winter iMay 10, 1887i. at Upernivik, in 

 places bare of snow, judging from the material gathered by C. 

 Rtder, the leaves are more erect 'Fig. 34 ^i: during summer 

 they are more spreading, and at that time the young leaves 

 pass gradually into the old ones; often also the young leaves 

 are red-coloured, as are those that have outlived the winter.

 to three new shoots are developed in the upper leaf-axils, but
