in a way that was not permissible it was not possible to collect all 
the material I should have liked; but I cut into the axis in several 
places and found leaf-bases still about an inch thick bearing buds 
which had no traces going back to the axis. In this connection an 
old wound on one of the trees should be mentioned. This wound 
had cut out an area of the leaf-bases about six inches square, 
leaving the axis itself exposed. No buds were formed in this 
region, though the leaf-bases round bore many, and some of these 
had exposed roots such as are shown in Fig. 9 (iii.) r and Fig. 11.

Fig. 11. Sketch of one of the irregular roots which stand out externally 
from the buds growing on the leaf-bases. Some roots like this tend to 
penetrate the bases again after growing for some time in the air. I, end cut off

Series of sections show that the “ buds ” are really attached to 
the leaf-bases. They arise in general on the upper surface of the 
base and grow directly upon it with no root or even definite 
constriction. The vascular cylinder of the bud tends to run through 
the flesh of the leaf-base for only a short distance, but may even 
penetrate an adjacent base. In any case it soon dies out, sometimes 
without seeming to connect definitely on to any of the vascular 
strands of the leaf-base. The diagram in Fig. 12 shows the attach¬ 
ment of such a “ bud.” This drawing is made from a longitudinal 
section through the whole structure.
