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 the west bank of the River Waikato, a little below Ngaruawahia. 
. Libocedrus doniana keeps always in the interior on high ground (500 to 
2,000 feet), from 35? to the Thames seems to be its limit. It is, however, 
strongly suspected that there are wo 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. Phyllocladus 
trichomanoides, which is plentiful at the north, from about 35° south (where 
it has been observed growing from the sea-side to 1,200 feet altitude), has 
its southern limit at 391? south, in the mountains inland west from Hawke 
Bay. Arthropodium cirrhatum, a common littoral northern plant, has its south 
limit at Cape Kidnappers, in 38° 50' south. Trichomanes elongatum has not 
been met with south of the Thames. Lowsoma cunninghamii, for a long 
time only found at one spot (the noted Kerikeri waterfall in the Bay of 
Islands), has been also met with at Whangarei and in the Coromandel 
ranges. Doodia caudata (or media), so very common at the north, has not 
been seen south of the Thames, except in one locality near Napier; this 
plant, however, may prove to be a distinet species. Gymnogramme lepto- 
phylla, plentiful near the head of Manukau Bay, has only been again met 
with at Ahuriri and Cape Kidnappers. Lygodium articulatum, a northern 
plant, has not been noticed south of the East Cape; and Schizea dichotoma 
appears to be wholly confined to the Dammara (kauri) forests. 
(8.) Plants found plentifully in the southern parts of the North Island, 
but rarely, if ever, extending north beyond the East Cape. 
Among these the following may be noticed:—Eleocarpus hookerianus, 
extending north to Tolaga Bay ; Hypericum gramineum, from the coast to 
600 feet altitude, has not been noticed north of Table Cape. Coriaria thymi- 
folia (several varieties), from the sea coast (Hawke Bay) to 4,000 feet, has 
not been generally met with north of Poverty Bay; but the very small 
leaved species, C. angustissima, was found in 1838 on Mount Hikurangi, 
East Cape, and subsequently near the summits of the Ruahine range, at an 
altitude of 4,500 feet. Discaria towmatou, a coast plant, has not been 
detected north of Poverty Bay. Potentilla anserina and Geum magellanicum 
extend from Cook Strait to the East Cape. Aciphylla squarrosa, found 
from the sea coast to 3,500 feet altitude, has not been noticed north of 
40? 30' south. Craspedia fimbriata, several varieties, from the coast to 1,000 
feet, extends north to the East Cape. Microseris forsteri, common near the
