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 Liypman and SxorrsserG 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
