New Zealand Flora , with a Reply to Criticism.

When we examine the zoning of these species, given above, it is 
clear that on the whole they are very old in New Zealand, for they 
take no notice of Cook’s Strait, between the fifth and sixth figures, and 
comparatively little of Foveaux Strait, between the tenth and eleventh. 
But this is no proof, without much confirmatory evidence from other 
countries, that they are absolutely very old. 
If from the list of families we exclude these which have just been con¬ 
sidered, it will be noticed that all the rest have their maximum of species to 
the south, sometimes towards the north end, sometimes towards the south 
end, of the South Island. If we take only those families which have 
a maximum in the zone 701-800 miles 1 (south of North Cape), or to the 
south of that, we get the following list of families :

Now if we zone these families from north to south, as'we did with the 
northern group, we get the result:

Both wides and endemics taper off from south to north, but, as in the 
case of the northern families, the endemics taper down far more rapidly.
