Measurements were made along two tertiary axes, A and B, which sprang from a 
secondary axis at nearly the same level. Measurements were also made along 
branches (quaternary axes) of these and are numbered from below upwards. Both the 
tertiary axes, and also the quaternary axes l-4 on axis A and 1-3 on axis B, had 
completed their growth in length ; the terminal part of Branch 6 on axis A had been 
broken off, so that the measurements cease abruptly (and its curves are not printed). 
The internode-subcurve of the tertiary axis A is rather irregular in the early part of 
its course, but comparison with that of tertiary axis B indicates that the first descent is 
due to the curve being transitional towards a descending one. The second depression is 
probably due to the external circumstances, as we note similar depression taking place 
in the displacement-subeurve at the immediately preceding point in tertiary axis B. 
The subcurves of the quaternary axes on axis A show admirable gradual transitions to 
the descending form. 
On several of the stems the branches were displaced upwards into a supra-axillary 
position. In the following skeletal sketch of these displacements, the number of each 
leaf is given first in Roman numerals and is followed by the number in ordinary type 
denoting the number of millimetres of upward displacement. 
Tertiary axis A: IX, ; XL, 4; XII, b; XIII, 3; XIV, 8. Tertiary aris B: xu 99; 
XIV, 4°5 (obliquely above the leaf); xv, 2°75 (obliquely above the leaf). 
Quaternary axes:—Third branch on A: vr, 29 (line of fusion very clear). Fourth 
branch on A: Iv, 3°5 (line of fusion very clear). Third branch on B: VI, 8 (line of 
fusion very clear) Fourth branch on B: vir, 11°5; VII, a.
