Diagram 7. Mirabilis longijlora. Explanation : — c. indicates the bundles derived from the cotyle- 
dons ; p . represents those of plumular origin. Whenever one important bundle fuses with another, or 
divides into two, the resulting strands are indicated, when necessary, by the next available higher 
figures. For instance, c. 1 (Fig. 1) divides into two ; the next available numbers are c. 5 and c. 6, 
so these are used to represent the two branches (Fig. 3). Again, c. 17 (Fig. 8) divides into c. 19 
and c. 20, then c. 15 and c. 19 join and so there is formed c. 23 (Fig. 10). Further than this the 
numbers are meaningless.
