Art. LXXIII.—On the Botany of Kawau Island: Physical features and causes influencing distribution of Species.

[Read before the Wellington Philosophical Society, 2nd September, 1876.]

In attempting a descriptive sketch of the botany of Kawau Island it will be necessary, for the better appreciation of the subject, to notice shortly some of

– 504 –

the influences which have contributed towards its existing facies. And first among these, and most important, is its geographical position.

Kawau, the property of Sir George Grey, K.C.B., stands as an outlying island on the east coast of the North Island, 27 miles north of Auckland, being one of many islands in that neighbourhood which no doubt at one time formed part of the main land, its proximity to the latter being distant only four miles, and possessing no higher altitudes, will naturally indicate a closely allied or nearly identical Flora.

The island is irregular in form, three and a half miles north and south, by three and a quarter miles east and west, and containing 5;200 acres of land.

According to Dr. Hector's Geological Report, the rocks from which the soil is derived are “palæozoic slates and tertiary sandstones.” On the higher ridges and spurs are found stiff clay and sandy soils, similar to much of that on the main land; on the lower slopes again the soil is much superior; and on the lower levels and small vallies it is very rich, as shown by the luxuriant vegetation growing there.

The indirect influence of arid soils has through the progress of time produced much of the varied features of the existing vegetation, as from drought on stiff clay or sandy soils, making repeated burnings easy, and preventing the growth of trees, hence the present amount of scrub land and fern. Again, at critical times the native grasses are burnt out.

The whole surface drainage of the island is westerly, the easterly side presenting a precipitous face, a part of the island in that direction having apparently been removed by the action of the sea.

This peculiar system of drainage is more strikingly seen in the Island of Kapiti, in Cook Strait, where the highest alitudes are situated along the edge of the seaward cliff, which at one time appears to have formed the longitudinal centre of the island.

Kawau, viewed from the sea as it is approached from the south or west, presents a most picturesque combination of headlands, bays, and smooth grassy downs, with large masses of bush, reminding one of the cultivated park scenery of Britain. Much of the surface condition of New Zealand before settlement possessed this park-like appearance, being especially fine in Southland; but in the clearer atmosphere of the North the colour-effects are more varied and pleasing.

Kawau is well watered by numerous streams, which fall into the harbours and bays which indent its westerly shores. The surface configuration being rounded, and the higher elevations under 600 feet, the rugged and grand does not exist, but in its place a quiet beauty reigns, much of it in places being the outcome of artistic cultivation. On shore, as the island is

– 505 –

traversed, the ever-changing scenery is beautiful, and the Fauna might puzzle the visitor as to his whereabout on the face of the earth. The Deer of Britain may be seen hurrying past to the covert; the Kangaroo of Australia, spanning across the path, pulls up erect to view the stranger; Tree Kangaroos from New Guinea are seen hopping up and down Puriri trees; the visitór is ever kept on the alert by the whírr of Californian Quail, or Chinese Pheasants, and the Wallabi Kangaroo, in numbers, keep zigzagging across his path; the Cape Barren Goose might also exhibit to him the unusual sight of a bird carrying her young under her wings The introduction of so many animals and plants must produce some influence on the indigenous Flora of the island either for good or evil in future years.

Flora of the Island.

The lists appended have no claim to be considered as exhaustive of the Flora of Kawau, and future collectors on the island may therefore search with hope of being rewarded for their labours by further discoveries both in native and introduced plants.

Many interesting plants collected by Mr. Kirk on the Great and Little Barrier Islands, and Arid Island to the eastward, do not seem to be found in Kawau. The absence of sufficient altitude may account for this with such species as Ixerba brexioides, Dacrydium colensoi, Phylloclades glauca, Archeria racemosa, and others, and the rare plant Pisonia umbellifera is not likely to be found so close to the main land.

Introduced species.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

A remarkable feature in the indigenous Flora of Kawau Island is the great number of orders and genera represented by so few species. The following are the proportions:—75 orders, 189 genera, 348 species and varieties, which give nearly 4 ¾ species to each order, and about 1 5/6 species to each genus. When it is considered that the entire number of phænogamic orders given in Hooker's “Handbook for New Zealand” is only 87, it must be admitted that the indigenous Flora is well represented in families, if not in species.

Introduced species.

In this list only three cultivated garden plants are included, the others being chiefly accidentally, or otherwise, introduced weeds. They are, although numerous in species, with few exceptions, not abundant in numbers, and are represented by 31 orders, 96 genera, and 125 species, thus showing the same disproportion of species to genera and orders as the índígenous Flora.

In Cryptogams, of which ferns and allies only are given, there are 2 orders, 25 genera, and 90 species, including varieties.

Botanical divisions of the Flora.

The botanical divisions may be popularly arranged under three groups: Grass, Scrub, and Bush.

Grass.

The lists of indigenous and exotic grasses and other pasture plants were noted at an early period of the season, and consequently some might have been overlooked. The number of species, however, in the list is great, although a few are worthless as food, and several others, although valuable, are neither abundant nor wide spread. There are 65 species, including varíetíes, in all, among which the following are abundant everywhere, and which may be said to constitute the main part of the pasture.

Dichelachne crinita, Dichelachne sciurea, Danthonia semi-annularis, Anthoxanthum odoratum, Holcus lanatus, Festuca myurus, Lolium perenne, Trititcum scabrum, Agrostis vulgaris, Poa annua, Poa pratense, Poa anceps, Trisetum antarcticum, Aira caryophylla, Dactylis glomeratus.

The early supply of food for sheep in spring depends largely on these fifteen species, and putting the comparative nutrient value of some of them aside, they may be considered the most valuable on the whole, as being available when most needed.

The following species on the list are worthless as food, and fortunately they are neither abundant or found on the pasture, being chiefly confined to the sea-shore:—

Spinifex hirsutus, Arundo conspicua, Festuca littoralis, Bromus arenarius, Bromus sterilis, Hordeum murinum, and Avena pratensis.

Among the remaining species on the list, several are valuable as pasture grasses, but seem to be either rare or confined to certain localities, as Sporobolus elongatus, and Stenotaphrum glabrum, both valuable because permanent, although inferior as sheep grasses.

The clovers are abundant and widespread, being adapted from their deep rooting to resist droughts.

The grasses on the more exposed ridges where stiff clay or sandy soil is present, are sparse, and suffer from the heats of summer. They are also liable to displacement by the growth of arid weeds, but the lower slopes and damp vallies carry a rich growth of superior grasses.

Stomachic plants are also present, so useful in preserving the health of stock. The following are common:—Parsley, Veronicas, Yarrow, Canadian Flea-bane, Centaury, etc.

There can be no doubt that the extensive pastures of Australia and New Zealand have been deteriorating during the past 20 years, and chiefly from the disappearance of the finer fibrous-rooted grasses, whose roots ramify near the surface of the ground. The cause of this is evident, by the exposure of

– 507 –

their roots to the excessive heat of the sun or frosts, from over-feeding with stock, and burning the grass at improper seasons. Any alleviation of this can only be obtained by the introduction of deep-rooting grasses; but the only permanent remedy will be got by the formation of resting-paddocks, or fenced divisions of the land, by which portions of the pasture may rest even for even a short time. Further notice of this does not, however, come within the limit of this paper.

Scrub.

The scrub vegetation of Kawau is the after-growth of fire, and at first is composed of species of arid growth, such as Leptospermum (Manuka), Coprosma (Mingimingi), Pomaderris (Kumarahou), Carmichaelia (Whakaka), Coprosma (Karamu), etc. Under the shadow and shelter of their close growth numerous young plants of the larger trees soon appear, with a host of smaller species, and thus, after a long period of time, if no other fire occurs, is the gradual renovation of the bush accomplished.

When the dense scrub land of Otago was first burned 20 years ago, a rich growth of Native grasses sprung up afterwards, producing a pasture of the first class. It is probable, however, that, in Kawau and similar arid soils in Auckland, an early sowing of grass seed during cool moist weather would be necessary to ensure success after burning.

Bush.

Under this head are included extensive patches of valuable timber trees in general, mixed with numerous species of smaller growth, which although ornamental have little commercial value except as firewood. The growth is dense and luxuriant; in places where the Nikau Palm and Tree Ferns are abundant, as in some of the deeper vallies, forming a close canopy of foliage overhead, a gloomy silence prevails, unbroken by the sound of animal life, the numerous opossums and birds finding a more congenial sphere above in the sunshine of the higher trees.

The indigenous trees which contribute most to seenic effects are Pohutakawa (Metrosideros tomentos) a valuable timber tree, in many places lining the shores of the island, and exhibiting a gorgeous beauty when in flower; Taraire (Nesodaphne taraire), having a rounded form of fine foliage; Puriri (Vitex littoralis), another valuable timber tree, with much of the sturdy gnarled aspect of the oak; Tawaapou (Sapota costata), with bright green foliage and rounded form; several species of pines (Podocarpus and Dacrydium), all valuable timber trees, and contrasting their peculiar small-leaved foliage with the large-leaved trees of the bush; Rewarewa (Knightia excelsa), a tall tapering tree, is a prominent object on the hill slopes. The wood of this tree makes beautiful furniture work. The following species are rare:—Tawhairaunui (Fagus fusca)—very few specimens of this tree

– 508 –

are now found on the island. Kauri (Dammara australis)—this valuable pine, with the last, is confined to the higher palæozoic rocks. Pukatea (Atherosperma novœ zealandiœ), always known by its large buttressed trunk, and Tangeo (Tetranthera calicaris), of which only one specimen was seen.

As the visitor on leaving the island recedes from Moana Bay by steamer, the extreme beauty of the landscape, as its features change by distance, is very pleasing. There is seen to great advantage that scientific combination of nature and art, which is ever the aim of the landscape gardener. The object often necessary as a principle of this science being architecture, we have here in the middle distance Sir George Grey's residence at the head of the bay, surrounded by rare and beautiful trees and shrubs, many of them sub-tropical. On the lawn may be seen Erythrina caffra, the coral tree, covered with brilliant scarlet flowers; Fourcroyia gigantea, a plant of the Amaryllis family, with remarkable flowers. This tree produces a fine fibre, and grows well without any cultivation on the worst clay hills. Foureroyia flavavirides, another fine fibre plant; Chamaerops excelsa, a palm tree also producing a fine fibre, and Chaemaerops fortunii, Bœhmeria nivea, another fine fibre tree belonging to the nettle family; Musa textilis, the Banana fibre tree from which the manilla fibre of commerce is procured; as also Musa sapientum, the fruit Banana, which yearly ripens fruit here; Brousonetia papyrifera, from which a kind of paper is made in Japan; Punica granatum the pomegranate; Olea europœa the Olive; a tree likely to become important in the North Island, from the oil product of its fruit as a commercial export; all the finest varieties of this valuable species are cultivated here. Arduina grandiflora, the Natal Plum, worthy of cultivation for its fruit; Ficus carica, the Fig tree, and several other species of this family; Anona muricata, the Custard Apple; Ceratonia siliqua, St. John's Bread tree; Eriobotrya japonica, the Loquat tree, which bears abundantly; Zingiber officinalis, Ginger, several species of this family; Stilingia sebifera, the Tallow tree, from which the Japanese manufacture candles. This plant, one of the Euphorbia family, succeeds well here. Quercus suber, the Cork tree, is represented by several large specimens; this tree is worthy of attention by the Forests Department. Several curious species of Japanese Oaks; groves of Aralia papyrifera, the Paper tree; Xanthorea hastilis, the curious Grass-tree of Australia; numerous species of Bamboos, including the gigantic Bamboo. These bamboos form good shelter hedges. When to this list are added Cinnamon, Camphor, Orange, Lemon, and Citron trees, sufficient proof is given of the existence of a remarkably mild climate.

It is Sir George Grey's opinion, that many of these valuable commercial plants are well adapted for the climate of Wanganui, and he is now making arrangements to send several young plants there as a trial.

– 509 –

The shore lines of massive Native trees flank this central portion of the landscape on either side; among them prominent, the Pohutakawa, in a full blaze of crimson blossom, harmonizing well with the dark green foliáge of the Puriri and Tawaapou trees. On the rising background, numerous large grown trees, Australian and American Pines, including species of Auracaria, Pinus, Cupressus, etc., add to the beauty of the scene by their artistic groupings, in some places their sharp-pointed outlines, as seen against the sky, contrasting finely with the rounded forms of the Native species, and their sombre green relieved by the pale silvery-white foliage of the Leucodendron argenteum trees from the Cape of Good Hope. The visitor, as the island fades away from his view, can only wish that a settled population may never be found within its shores, and that its peace and beauty may always remain undisturbed.
