whose chief habitat is around the Bay of Islands, where, in shady dry 
woods, it is plentiful ; A. macrophylla, was found at Te Whau, Manukau. 
Bay, in 1841 ; and, subsequently, a few plants of A. Banksii in one spot 
in the dense forest between the river Manawatu and Wairarapa, but none . 
intermediate ! ascending to nearly 1000 feet. Geniostoma ligustrifolium, 
abundant at the Bay of Islands, and farther north, ascending to 1200 
feet; a straggling plant (having thicker leaves) has been seen as far 
south as the woods at Hawke’s Bay; the only plant, however, noticed 
south of the Hast Cape. Vitex littoralis, a tree very plentiful at the 
north, extending quite across the Island, and growing as diffusely on the 
immediate sea coast as on the high lands, ascending to 1500 feet; is 
little known south of the East Cape ; one tree however is said to be on 
the islet Mokoia in the large lake at Rotorua, and one is also at Table 
Cape (north side), its extreme southern limit. <A vicennia officinalis, a 
maritime plant, very plentiful from the North Cape to about 374° south ; 
the mouth of the Waikato river on the west, and within Tauranga 
harbour on the east coast, being its south limits. Persoonia Toro, has 
not been met with south of Whangarei Bay. Santalum Cunninghamii, 
and its vars., plentiful at the north, has not been noticed south of 38°; 
yet, at the head of the Wairarapa valley, (just at the entrance of the 
long forest,) in about 41° south, two trees were most unexpectedly found 
standing together ; no more however were detected in a journey of 3— 
4. days through that forest, performed on several occasions. Z'rephis 
opaca, (or, Epicarpurus microphyllus,) has its south limits at Tolaga 
Buy, or about 39° south. Dammara qustralis, which grows from the 
sea side to an altitude of 1500 feet, in nearly all soils and situations, 
(though its favorite soil is a stiff sterile clay,) is very plentiful quite 
across the Island from the North Cape to the Thames, but has its limits 
on the east coast at 374° south, and on the west coast at Kauri river 
(Kawhia), 38° 4° south, where are a few stunted trees. The writer 
well remembers seeing, in 1841, a straggling tree on tle west bank of 
river Waikato, a little below Ngaruawahia. Libocedrus Doniana, keaps 
always in the interior on high ground (500 to 2000 feet), from 35° to 
the Thames seems to be its limits. It is, however, strongly suspected, 
that there are two species of this genus in the North Island; the 
Libocedrus growing in dense thickets on the Ruahine Mountains, has 
never yet been found in fruit,* and appears in foliage different from 
the Bay of Islands plant, which is also of more robust growth.
