usually continues its growth in a vertical direction, larger 

 leaves are developed, and the growth can be terminated by 

 a few-flowered raceme without a terminal flower. Special 

 bud-scales do not occur; during the winter-rest the point of 

 the axis is protected by the uppermost, not yet expanded pair 

 of foliage-leaves, which are in con- 

 tact with each other by their hairy 

 margins. After the fruit has ripened, 

 the stem dies as far down as to some- 

 what above the boundary line be- 

 tween the 1st and 2nd year's growth ; 

 the perennial basal portions bear 

 the innovation shoots. Principal 

 buds proper do not occur, but the 

 uppermost buds appear generally 

 to be the most advanced, and it 

 is evidently especially these buds 

 which produce the flower-bearing 

 axes, while the lower ones often 

 produce only small, weak, few- 

 leaved shoots which — as recorded 

 by Warming (1890, ' p. 205) and 

 as also shown in Fig. 1 — may 

 be somewhat runner-like and fur- 

 nished with only a few small leaves. The specimen illustrated 

 in Fig. 1 is rather scantily branched ; each of the floral shoots 

 has only two real "innovation-buds", and of their parent- 

 shoots the one to the left has also had two, of which one 

 has developed into a vegetative shoot; the parent-shoot to 

 the right is somewhat more richly equipped: in addition to 

 the lowermost quite small shoot it bears two opposite floral 

 shoots, and in the axils of the next pair of leaves two more 

 shoots, of which the one (cut-off) was floral. Such a difference
