green in colour than are the older ones, which are more down- 
wardly directed (Fig. 4 F). 
The flowers, numbering from two to six, are aggregated 
in a terminal, umbelliform inflorescence which arrests the growth 
of the branch, and which passes the winter protected by arched 
scale-leaves (Fig. 4 F). The floral buds are larger and more 
globose than are the vegetative ones (cf. Fig. 4 A and F). 
No foliage-leaves occur between the scale-leaves and the 
inflorescence.

After flowering two or more new shoots arise immediately 
below the dead apex of the shoot and dichotomy takes place. 
The flowers, which have large, thin bracts, scale-like and 
curved, erect or more or less inclined, are formed during the 
year previous to that in which they expand and reach in the 
development of their different parts at least to the stages shewn 
in Fig. 4 B—E. 
The corolla is widely bell-shaped (12—17 mm. wide) and 
purple in colour: in its interior, immediately above its base, 
it bears a ring of short hairs, probably as a protection to the 
honey which is secreted by the low, ring-shaped and some-
