New Zealand and their Distribution.

Now if Natural Selection were the determinant, one would hardly expect, 
when one considers the extremely different climatic, geological, and other 
conditions of these widely separated islands, that they would, so to speak, 
choose their floras from just the same families. One would anticipate 
finding considerable differences between them, and that more of the 
other important families of New Zealand would occur, or that the islands 
would contain relicts belonging to some of the less important families in 
New Zealand. 
(1) We shall therefore expect to find that the islands have proportionately 
more in common with Stewart in the matter of families than with New 
Zealand proper.

Thus all the islands, even the Kermadecs, contain a considerably 
higher percentage of Stewart families than they do of New Zealand families. 
All the Auckland families occur in Stewart, 41 out of 48. or 85 per cent., 
of the Chatham families, and even 28 out of 37, or 75 per cent., of the 
Kermadec families. 
(2) We shall expect to find that a large part of the families in the different 
islands are the same, and that most of them are selected from the Stewart 
list. The following table gives, in ordinary type, the 60 Stewart families, 
with the islands in which they occur. Those not occurring in Stewart are 
printed in capitals.
