Looking at the points of contact bétween the two floras afforded by 
Leguminose alone, the relationship appears but slender. This order, 
which stands second only to Composite amongst flowering plants in the 
number of species it contains, includes more than one-eighth of the 
Phanerogamia of Australia, where it comprises nearly as many species as 
are found in the entire Phanerogamic flora of New Zealand; yet, amongst 
the thousand Australian forms not one is common to both countries, a fact 
which is the more remarkable as the seeds of most plants of this order 
suffer less than others when drifted by marine currents. The seeds of 
Entada scandens are drifted from the shores of Northern Australia to the 
coast of New Zealand, and have been picked up even on the East Coast as 
far south as Tauranga. It is certainly matter for remark that no sea-borne 
seeds of Acacia or other large Australian genera appear to have germinated 
on the New Zealand coasts. 
Three genera of this order, however, are common to both countries, and 
the first two are not found elsewhere. Clianthus, of which a single species 
is endemic in the extreme northern portion of New Zealand, and another in 
Australia, the first being a glabrous undershrub, the second a pilose herb. 
Swainsonia, which is represented here by a single species confined to the 
Southern Alps, and by numerous species in Australia. Sophora has two 
species in Australia and another in this colony, but belonging to a different 
section of the genus. Carmichelia and Notospartium, the only additional 
genera in New Zealand, are endemic, and have no near allies in Australia. 
Both countries are characterized by a great paucity of Rosacem. In 
New Zealand we find four genera and thirteen species; in Australia, seven 
genera and seventeen species; four genera and four species being common 
to both. 
In Saxifragezm, the relationship is generic only. Quintinia and Ackama 
not being found elsewhere, and Weinmannia having a wider distribution. 
Drosera is largely developed in Australia, where it comprises forty-one 
Species, five of which extend to New Zealand, but with the possible excep- 
tion of D. spathulata, are not found in other countries. In Haloragesm, four 
genera and eight species are common to both countries. 
Myrtaces ranks next to Leguminoss, in the extent to which it imparts 
2 peculiar character to the Australian flora, but has only a single species 
common to both countries. Metrosideros, Myrtus, and Eugenia are repre- 
sented by different species in each country. 
Epilobium, a genus developed in New Zealand to a remarkable extent, 
has six species common to both countries, four of which are not known to 
occur elsewhere. 
Of umbelliferous plants, eight genera and six species are common to 
both countries. The trimorphic araliads of New Zealand have nothing to 
represent them in Australia.
