Bucwanan.—On the Botany of Kawau Island. 505 
traversed, the ever-changing scenery is beautiful, and the Fauna might 
puzzle the visitor as to his whereabout on the face of the earth. The Deer 
of Britain may be seen hurrying past to the covert; the Kangaroo of 
Australia, spanning across the path, pulls up erect to view the stranger ; 
Tree Kangaroos from New Guinea are seen hopping up and down Puriri 
trees; the visitor is ever kept on the alert by the whirr of Californian Quail, 
or Chinese Pheasants, and the Wallabi Kangaroo, in numbers, keep zig- 
zagging across his path; the Cape Barren Goose might also exhibit to 
him the unusual sight of a bird carrying her young under her wings 
The introduction of so many animals and plants must produce some influence 
on the indigenous Flora of the island either for good or evil in future years. 
Flora of the Island. 
The lists appended have no claim to be considered as exhaustive of the 
Flora of Kawau, and future collectors on the island may therefore search 
with hope of being rewarded for their labours by further discoveries both in 
native and introduced plants. 
Many interesting plants collected by Mr. Kirk on the Great and Little 
Barrier Islands, and Arid Island to the eastward, do not seem to be found 
in Kawau. The absence of sufficient altitude may account for this with 
such species as Iwerba brewioides, Dacrydium colensoi, Phylloclades glauca, 
Archeria racemosa, and others, and the rare plant Pisonia wumbellifera is not 
likely to be found so close to the main land. 
Indigenous Species. 
A remarkable feature in the indigenous Flora of Kawau Island is the 
great number of orders and genera represented by so few species. The fol- 
lowing are the proportions :—75 orders, 189 genera, 848 species and 
varieties, which give nearly 41 species to each order, and about 1$ species 
to each genus. When it is considered that the entire number of phano- 
gamie orders given in Hooker's ** Handbook for New Zealand ” is only 87, 
it must be admitted that the indigenous Flora is well represented in families, 
if not in species. 
Introduced species. 
In this list only three cultivated garden plants are included, the others 
being chiefly accidentally, or otherwise, introduced weeds. They are, 
although numerous in species, with few exceptions, not abundant 
‘and are represented by 31 orders, 96 genera, and 125 species, thus show- 
ing the same disproportion of species to genera and orders as the indigenous 
Flora. 
In Cryptogams, of which ferns and allies only are given, there are 2 
orders, 25 genera, and 90 species, including varieties.
