The terminal buds on the branches were very small in July; 

 they are protected by the basal part of the uppermost foliage- 

 leaves. The lateral buds are also protected by the erect basal 

 part of the petioles (Fig. 25 A, B). The buds bear scale-leaves, 

 greenish or reddish in colour which merge by easy stages into 

 foliage-leaves (Fig. 25 E). In spring the terminal buds are the 

 first to develop, and then the axillary buds in succession from 

 above downwards, but this succession is not always strictly 

 observed. The lowermost buds on the year's shoots may remain 

 dormant for several years, and may then develop. The inflores- 

 cence is terminal. When it has completed its growth a strong 

 lateral shoot is given off immediately below it (Fig. 25 E), often 

 forming a sympodium with the parent shoot. 



The inflorescence is a many-flowered raceme and is formed 

 during the year previous to that in which it opens; it passes 

 the winter naked with its flower-buds well- developed (the spe- 

 cimen shown in Fig. 25 В is from Denmark in the month of 

 July). It is drooping (Fig. 25 B, C), and has no foliage-leaves, 

 only subtending scale-leaves, and two bracts at the base of each 

 flower-stalk. 



The corolla, which turns its throat downwards, is more 

 brightly coloured and more conspicuous than in A. alpina : 

 whitish with a tinge of red, the limb of a deeper red. It varies 

 somewhat in size (from 4 to 6-5 mm. in length; the limb from 

 3 to 3-5 mm. in breadth; throat from 1-25 to 1-75 mm. in width). 

 The throat is wider than in A. alpina. The interior of the 

 corolla is covered with small, stiff hairs to which the pollen- 

 tetrads (Fig. 26 G) adhere for a long time (Fig. 26 L]. The hairs 

 do not extend so far towards the margin as in A. alpina. 



The stamens are half as long as the pistil (Fig. 26). The 

 two appendages which proceed from the anthers extend first in 

 a straight line and then curve upwards; they are rough with 

 small prickly hairs (Fig. 26 Я, N). Lindman found specimens in
