IN NEW ZEALAND. 45 
species of Rubus in fruit (219), a shrubby plant, climbing 
over the bushes and young trees near it. Some natives 
informing me of a new and peculiar tree, which grew 
on Mokoia, the island in the middle of the lake, I crossed 
to it, and sought for the same, but found nothing new. 
From subsequent information, I was led to conclude that the 
tree of which I had been in quest was no other than the 
Vitex littoralis of X. Cunn. ; one individual of which, accord- 
ing to the natives grew on the island, but not another in the 
whole district. I observed the natives continually masticat- 
ing a kind of resinous gum, which was insoluble in water, 
and did not decrease through the process of repeated 
chewing; this, they informed me, they procured from 
the Pukapuka (Brachyglottis repanda, A. C.), assuring 
me that the swallowing of the substance would cause 
death. They pointed out the shrub, which, although 
slightly differing in general appearance, bore a strong re- 
semblance to Cunningham's plant; yet asit was neither 
in flower nor fruit, I did not colleet any specimens. It may, 
however, prove new. Mr. Chapman has kindly promised 
to procure me some of the resinous matter, and specimens 
of the shrub when the season comes. Through the kind- 
ness of the same gentleman l obtained, from a spring in 
the neighbourhood, several specimens of siliceous matter, 
deposited by the waters of the springs on twigs, leaves, &c. 
lying in it, some of which I inclose in the case now sent. 
The lake contains an abundance of small cray-fish, which are 
very good eating. Here are also two small kinds of fish, 
called by the natives Kokopu and Inanga, and a black bivalve 
a species of Unio; the whole of which are common in most of 
the fresh-water streams in New Zealand. 
Jan. 13th. — Early this morning I left Te Ngae. Crossing 
the lake to the N.W. extremity, I landed, and once more 
recommenced my journey. We soon entered the dense 
forest, through which the road to Tauranga lies, and in which 
we travelled until sunset. Here, in a low, wet, and shaded 
spot, I noticed another new and peculiar species of Lomaria
