In the succeeding Tables the horizontal series of numbers represent the lengths in 
millimetres of the successive segments of an axis, the nature of which is indicated in the 
left-hand column. Branches springing from the axils of leaves actually or phylo- 
genetically belonging to the same node are bracketed in the left-hand column. The 
branches are numbered successively upwards. The vertical columns, so far as they refer 
to measurements of branches, thus give means of comparing the lengths of corresponding 
segments of the successive branches.
