5 towering aloft in silent grandeur, can never fail to strike the beholder with astonishmment and awe: a feeling sense of his own littleness and span-like existence - of admiration at "the (living) high embowered roof, with antique pillars massy proof, - casting a dim religious light," - (ending perchance in lofty thoughts tending towards immortality,) is sure in such umbrageous retreats to steal over him.

6. Of our shrubs and smaller timber trees, several are of strikingly beautiful growth, or blossom, or foliage; and are often seen to advantage when standing in some clear glade, or on the outskirts of a forest:- (e.g.) the Houhere, Hoheria populnae (a) and its varieties; the Horopito, Drimys axillaris; the Manuka-rau-riki, Leptospermum ericoides; the Kohuhu, Pittosporum tenuifolium; the Kowhai, especially the smallleaved mountain variety, Sophora tetraptera var.: grandiflora; the Koromiko-taranga, Veronica, several species; the Mairehau, Phebalium nudum; the Toro, Persoonia Toro; the Pukapuka, Brachyglottis repanda; the Northern Maire, Santalum Cunninghamii; the Tawari, Ixerba brexioides; the Tipau, Myrsine Urvillei and M. salicina; the Tangeao, Tetranthera calicaris; the Ramarama, Myrtus bullata; the Ti, Cordyline australis; the Kahikomako, Pennantia corymbosa; the Pate, Schefflera digitata; the Horoeka, Panax crassifolia: and, on the sea-coast, the Karaka, Corynocarpus laevigata; the Karo, Pittosporum crassifolium; and the truly evergreen Ngaio, Myoporum laetum, (fit symbol of vigorous health on its barren and desolate beaches!) - while the tree ferns are universally praised for elegance of form and, wherever seen, add an indescribable charm to the landscape, and draw willing homage from the delighted admirer.

7. The large virgin forests are generally composed of trees different in genera and sizes. The Kauri pine is always associated with other trees; yet, its loftiness, its colossal bulk, and peculiar growth, (including a huge mound of 8-12 feet alt. around its base, composed of its own fallen deciduous scales of outer bark,) ever gives the forest in which it grows a highly characteristic appearance, so that such is truly a Kauri forest. A few only of our timber trees can be said to form large forests of a single species; such as, (on the low grounds,) Kahikatea, or White Pine, (Podocarpus dacrydioides); this alone of all the timber trees is chiefly found growing thickly together. The Totara, (P. totara) may also sometimes be found forming clumps or groves. Te Tawhai, or Black Birch, (Fagus Solandri,) is frequently, in the south parts of the Island,

6 the prevailing tree on the sides of clayey hills, where it forms continuous woods. The Tawa (Nesodaphne Tawa), on both dry hills and low alluvial grounds, is commonly found forming large forests. On high grounds in the interior, especially on the old sandstone (Palaeozoic), the Tawhai-rau-nui (Fagus fusca) often grows together in large forests; and the peculiar glory of these woods is, their openness and freeness from underwood, so that a traveller may run through them - to the great danger, however, of losing the track. And, at a much higher elevation, - 4000 to 6000 feet, - on the top of the mountain ranges, grows an allied species, F. Cliffortioides; and with it many small tough thick-growing gnarled shrubs as underwood, which can only be passed by walking on (not among); and which, with the prostrate and concealed rotten trees and branches, sadly tires the traveller's strength and patience, causing him to wish he was again in the low alluvial woods by the water-courses, among the supple-jacks, polygonums and brambles! -

8. In order, however, that the Botanical Geography of this large island, may be the better known, especially to those at a distance, it will be necessary to go a little into detail, and to show the same, as far as practicable, from its insular position, climate, and situation; as well as from a brief comparison of its Botany with that of the nearest lands. In doing this the phaenogamous genera and species, including also Ferns, endemic to our island, will be particularly noticed; and those plants which are very local in their habitat will be pointed out. For, although the general climate of the whole island is temperate and genial, (extending as it does from 34° to 42° south, and with only two elevations above the line of perpetual snow,) several of its vegetable productions are remarkably local. And, that this may be the more naturally and readily perceived, it is purposed to show the same in two ways:- (1.) by area corresponding more or less to its degrees of latitude; and (2.) by zones increasing in altitude surrounding the island. (b)

9. Of phaenogamic GENERA which (as far as is at present known) are peculiar to the North Island of New Zealand, the following may be mentioned, viz., - Entelea, Ackama, Ixerba, Alseuosmia (several species), Colensoa, Rhabdothamnus, Nesodaphne (2 sp.), Dactylanthus, and Adenochilus; and of Ferns, Loxsoma. And of endemic SPECIES of genera hitherto unknown to the other New Zealand Islands, the following phaenogams, viz., - *Phebalium nudum; Pomaderris (3.), elliptica, Edgerleyi, and phylicifolia; Clianhus puniceus; Eugenia Maire; Meryta Sinclairii;
