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. 34 C). In West Greenland, Vanhoffen found a form 

 subintegrifolia Abrom. (1. с PI. V, Fig. 3) 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.

A, A flower in its first stage of development; two antisepalous stamens are bending over the 

 middle of the flower, and have their anthers open; the stigmas are in the same stage of 

 development as those shown in Fig. B. C, From a flower, the stigmas of which are func- 

 tional; there is already pollen upon them. D, Longitudinal section of pistil at a some-

The leaves remain green throughout one winter, but stay 

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

 (Fig. ^i A, B). During winter (May 10, 1887), at Upernivik, in 

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

 Rtder, the leaves are more erect (Fig. 34 A); 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. 



The branching. Below the terminal inflorescence one 

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