Fig. 45 Illustrates the positions of the bundles in the upper 
and lower regions of the leaf. 
A transverse section of a leaf, just above its junction with 
the stem, shows the general arrangement of the bundles, the 
largest one (1) being in the centre. Intercalated between the 
larger bundles are smaller ones, sometimes consisting of quite 
a few elements ; these small bundles may completely disappear 
higher up in the leaf. The diagram A in Fig. 45, PL VII, 
shows the bundles in the upper regions of the sheathing leaf- 
base ; all the bundles here represented are to be found in the 
higher portions of the leaf, although their relative positions are 
different. In order that this may be followed more easily the 
bundles have been numbered, those having the same number 
in the two diagrams being identical. 
As the bundles pass up the leaf the first changes in position 
noticed are: 2 and 11 in the sheathing base move towards 
the convex side, and the bundles of the horns of the crescent 
gradually travel obliquely up towards bundle 1. 
The large bundle 1 remains in practically the same central 
position. 
The bundles 3 and 10 travel in such a way as to retain their 
relative position with regard to bundle 1. Passing upwards 
from the sheathing base, the bundle 9 moves towards the plane 
(ventral) surface of the leaf, taking up a position below and 
a little to the right of 1 ; bundle 4 does likewise, taking up 
a similar position on the left side of 1. Before the bundles 4 
and 9 have taken up their final position (shown in B), it was 
found that three new bundles arose near the periphery of the 
convex (dorsal) side of the leaf, and almost opposite to the 
bundles i, 3, and 10 ; they are indicated by the letters a, b, 
and c in diagram B. 
All the bundles have now left the sheath; a branch is then 
given off from 6 and joins up with 4, and subsequently a branch 
from 7 unites with 9. Bundle 6 now gives off another branch 
(6'), which runs up the leaf in a position between the two first- 
named bundles. Bundle e, which occupies a similar position 
to 6 ' in the opposite side of the leaf, was found not to be
