NOTES. 
Par. 6. Note, a.— Hohcria populnea: the Botanist Allan Cunningham, (who first 
visited this North Island of New Zealand in 1826, and who created this genus,) was 
an accurate and enthusiastic observer of Nature ; he thus characteristically and truly 
notices the beauty of this tree, in drawing up its generic character, (published in 1836,) 
—“ Arbuscula, spectabilis, sempervirens ct maxime omata iu sylvis naturalibus iis.”__ 
Ann. Nat. Hist vol. iii. p. 313. 
Par. 8. Note, b. I had also drawn a third division, or classification, of many of 
the plants of the North Island, according to its geognostic formation ; but I have been 
obliged to abandon it, chiefly through want of space. No doubt, hereafter, it will bo 
both interesting and useful to show the geognostic habitats of the various species,— 
whether on Clay or Alluvial Soils, — on Limestone, Sandstone (Paleozoic,) or Volcanic 
formations, Ac. I feel assured, that much more attention is absolutely needful to this 
branch of the science than has hitherto been given it, as a necessary step towards tlio 
solving of the great problem concerning the Distribution of Plants. ’ I remember well 
(in 1845) being forcibly struck with seeing certain Bay-of-Islands plants, (e. g. Metro - 
sideros seandeus,Gaultheria antipoda , Conlyline xtricta, Lindsaa linearis , Lycopodium 
volubile, &c.,) on the clayey hills near Wellington. — Plants, which I had not beforo 
Been south of the Thames. I may also mention that, iu 1844, Dr. Hooker published 
(in the “ I.ondon Journal of Botany,” vol. Ill,) the names, &c,, of a Collection of 123 
Plants made in the neighbourhood of Wellington by a visitor, of which number only 2, 
or perhaps 3, were not identical with the Bay of Islands plants. Hence arose a suspi¬ 
cion, that the North Island of New Zealand possessed but few species, seeing that the 
Barne plants were collected in latitudes so far apart. But the fact is, that the same 
geologic features obtain on those hills, as at the Bay of Islands, although but rarely 
intermediate. And many of those species (as far as I know,) are not elsewhere found 
between 36° South und Cook's Straits.

Par. 12. (i.) Note, c. The Poliutukuwa ( Metrosideros tomentosa ) is truly a littoral 
plant; and yet (in 1811,) I detected it growing on the Sandstone rocks of the high 
inland lake Waikare, about 70 miles from the sea ; and I find, from DiefFenbach, (vol. 
i. p. 384,) that he too had observed it growing on the trachytic cliffs of the inland 
lake Tarawera, (1075 feet alt., apud Roclistetter,) at about the same distance from 
the sea. 
Par. 12. (ii.) Note, d. The Knraka ( Corynocarpus lavigata) is naturally a coast 
plant; but it is sometimes found growing in the interior, in clumps or singly,— 
particularly in the more Northern parts, and on the shores of lake Taupo,—where it 
has been planted a3 a fruit-hearing tree by the New-Zealanders. 
Par. IB. (iii.) Note, e. “Fagusfusca has not been seen north of Poverty Bay." 
In 1839, however, I visited a small isolated wood of Fagus at the head of Whangarei 
Bay, but failed in getting any fruiting specimens. That plant, from its vernation, is 
believed, by the writer, to be a different species, or, at all events, a marked variety. 
{Vide, “ London Journal of Botany,” vol. III., p. 20.) The same tree grows also 
near Kaitaia Mission Station, North of 35 0 South. By the Northern Natives, it is 
called Hutu • 
Par. 16. Note, f, Dr. Sparmann seems scarcely to havo been done justice to ; no 
New Zealand plant beurs his name. G. Forster, however, in his “Voyage round the 
World, (vol. i. p. 67? 4to. ed., speaking of his father and himself, while collecting 
specimens at the Cape, on their voyage out with Captain Cook,) says — “ Our abundant 
harvest gavo us the greatest apprehensions that with all our efforts, we alone would be 
unequal to the task of collecting, describing, drawing, and preserving (all at the same 
time) such multitudes of species, in countries where every one we gathered would in all 
probability be a nondescript. It was therefore of the utmost importance, if we meant 
not to neglect any branch of natural knowledge, to endeavour to find an assistant wcdl 
qualified to go hand and baud with us in our un lertukiugs. We were fortunate enough
