usiially continues its groNvth in a vertical direction, larger 



leaves are developed, and the growth can be terminated by 



a few-flowered racerne 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 fruithasripened, 



the stem dies as far down as to some- 



what above the boundary line be- 



tween the Ist and 2nd year's growih ; 



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
