So too with regard to the European genera and species, there { 
ies found in New Zealand but not in Australia, such as —

j points of affinity betwen Australia and New Zealand, these ar« 
and decided as to render the dissimilarities all the more singular. 
In the first place, there is no New Zealand Order absent from Australia except Coriariece, 
Brexiacea, and Chloranthacea, which are single genera rather than Orders. Of the 282 genera of 
Phamogams in New Zealand, 240 are also Australian, and 60 are almost confined to these two 
countries. The greatest amount of generic affinity exists in thi-ee of the largest Orders in each, viz. 
Composite, Orchidece, and Grammes, which may be considered generically identical in both. To this 
category of resemblances also belong the antarctic genera and representative genera, many of which 
are also found in America, and which will be hereafter considered. Of these 240 genera, by far the 
larger proportion are confined to eastern Australia, not one being exclusively western Australian. 
Descending to species, I find that 216, or one-fourth of the New Zealand Phamogams, are natives 
of Australia,* and of these 115 are confined to these two countries. Of the remaining 101, 77 are 
common to America, 75 to India, and 52 to Europe. The comparatively small number of these that 
are common to India, and greater number common to America, is a remarkable fact, considering the 
relative position of these countries ; and the large number of European genera is no less so. 
Another interesting anomaly is, that of the 115 species peculiar to Australia and New Zealand, 
only .26 belong to genera peculiar to those countries, and only 6 to the long list of Australian genera 
that contain upwards of 20 species each. Again, upwards of 20 of these 115 are scarce and chieflv 
alpine plants in both countries, occupying comparatively very small areas; whereas of the 101 that 
are found in other lands besides Australia and New Zealand, only 5 or 6 are alpine, and most of these 
are antarctic also. 
Thus, under whatever aspect I regard the Flora of Australia and New Zealand, I find all attempts 
to theorize on the possible causes of their community of feature frustrated by anomalies in distribu- 
tion such as I believe no two other similarly situated countries in the globe present. Everywhere 
recognize a parallelism or harmony in the i 
a common features of contiguous Floras, which
