terranean runner is round, the assimilatory shoot is angular 

 owing to the edges of the decurrent leaves (Fig. 27 C). The 

 year's shoots are unbranched; they have scale-leaves at their 

 bases. It is a usual thing for the terminal bud to die and 

 then the apex of the shoot has the form of a small, pointed 

 cone (Fig. 28 L; Fig. 27 C). The uppermost lateral bud gene- 

 rally continues the growth sympodially. Besides this bud, from 

 one to three of the other upper lateral buds may grow out. 

 The foliage-leaves fall in autumn. The buds are protected by 

 scale-leaves which sometimes persist at the base of the year's 

 shoot even after the leaves have come out.

(E. W., 1884.) 



The flowers occur singly in the axils of one or two of the 

 lower foliage-leaves on the year's shoot, but rarely in the axil 

 of the uppermost scale-leaf. They are 4- and 5-merous. 



The corolla is urceolate-globose (Fig. 28). and entirely 

 glabrous. Usually it is of a dull deep-red colour, but according 

 to LiNDMAN and Skottsberg on the Dovre and in Lapland the 

 colour is much deeper than in the lowlands. The length is 

 from 4 to 5 mm., the width of the throat is 2 mm. 



The filaments are bent inwards towards the style, and the 

 anthers stand erect, parallel to the latter (Fig, 28 B]. The pores
