Table VIII shows at a glance that the ‘wides’ and endemics are 
arranged as predicted, the former much the commoner, and both in 
graduated series, the one with numbers increasing upwards, the other 
with them increasing downwards. 
If it be preferred to include as endemic to New Zealand those species 
which also occur in the outlying islands, we get the result shown in the next 
table, which corresponds to column H or J in the imaginary history of the 
Ceylon species given on p. 20 of the preceding paper in this volume.

The arrangement of the plants in the different classes is very much the 
same as in the preceding table, but the endemics begin to show an accumu- 
lation at the top of the list , 1 though from the third class onwards they show 
the same graduated series as in the other table. 
The regular arrangement of the endemics in the various classes from 
top to bottom of the scale is by itself almost enough to show that natural 
selection cannot be responsible for their distribution, but it may be enor- 
mously strengthened, as in the case of Ceylon, by a comparison of the 
different families and larger genera. These all, if of reasonable size, agree 
in the arrangement of their members with the total of the flora, and it will 
suffice to give as examples half a dozen of each, chosen by drawing the 
numbers from a hat.
