one is indigenous to New Zealand, which, however, possesses two endemic 
species, one representing the nucumentaceous section of the order, the other 
the folliculaceous section ; the former belongs to Persoonia, a genus largely 
developed in Australia, but not known elsewhere ; the latter to Knightia, of 
which one other species is known in New Caledonia. The large genus 
Pimelea, restricted to New Zealand and Australia, comprises nearly seventy 
species in the latter country and ten in the former, but except P. longifolia, 
which extends from this colony to Lord Howe’s Island on the Australian 
coast, no species is common to both floras. 
Fagus, which forms so large a part of the mountain forests in New 
Zealand, is represented in Australia by three species, all of which are 
endemic. 
In Conifers there is no species common to both countries; the common 
genera Dammara, Podocarpus, Phyllocladus, and Dacrydium; except Podocar- 
pus, each is represented by a single genus in Australia, but Phyllocladus and 
Dacrydium are especially characteristic of New Zealand, the first having 
three species, one or other of which is found scattered throughout the colony 
except in the driest districts; the other contains seven species, some of 
which occur in all districts. In this, as in many similar cases, the Australian 
flora has been influenced by that of New Zealand rather than the reverse. 
A much larger proportion of Monocotyledons is common to both countries, 
chiefly owing to the wide distribution of many species of Cyperacew and 
Graminez. 
In Orchidaces there is a close generic relationship, no fewer than sixteen 
genera being common to both countries, but not more than six species, two 
alone of which are found elsewhere ; the restricted distribution of the species 
of this order is strongly marked all over the world. 
Astelia, a liliaceous genus largely developed in New Zealand, is repre- 
sented in Australia by a single endemic species. Juncem has eight species 
common to both countries, six of which are found nowhere else. 
Twelve genera of Cyperacez, and thirty-two species, are common to both 
floras; many of the species exhibit a wide distribution, and not more than 
twelve are restricted to Australia and New Zealand. 
In Graminew the relationship is still more strongly marked, more than 
half the New Zealand species, and twenty-five genera out of twenty-seven, 
being common to both countries; only ten of the species are restricted to 
these countries, many of them having a wide distribution. 
In ferns and allied plants, the proportion of species common to both 
countries is still larger. Australia exhibits two hundred and thirty-two 
Species, comprised under forty-seven genera; New Zealand has thirty- 
nine genera and one hundred and fifty-three species. ga me genera
