In addition to purely tropical fruits a number of semi-tropical fruits are grown on our eastern seaboard, but are not entirely confined thereto, as many of them are cultivated to a considerable extent in some parts of our coastal and inland tablelands, particularly in sheltered positions. Under the heading of semi-tropical fruits, all kinds of citrus fruits, persimmons, loquats, date palm, wine palm, pecan nut, Brazilian cherry, Natal plum, ki-apple, and many other fruits are included, as well as several fruits that more properly belong to the temperate regions, such as Japanese plums, Chickasaw plum, peaches of Chinese origin, figs, mulberries of sorts, strawberries, cape gooseberries, &c. Of all of these the citrus fruits, which include the orange, mandarin, Seville, lemon, lime, grape fruit, kumquat, citron, and pomelo are by far the most important, and are grown successfully over a very large portion of the State, so that we will consider them first.

CITRUS FRUIT.
Quite a number of fruits are included under this heading, and all reach a very high state of perfection in this State. The whole of the family, the lemon-shaped citron excepted, is noted for the beauty and symmetry of growth that its trees make, and I know of few more beautiful sights in the vegetable world than a well-kept citrus grove in full bearing. Take the common round orange as an example, its well-balanced and evenly grown head, its dark glossy green foliage, its wealth of white blossoms, which perfume the whole neighbourhood, or its mass of golden fruit between its dark-green leaves, render it one of the most beautiful of fruit trees at all times, but especially so when covered with blossoms or ripe fruit. A typical Queensland grove is even more beautiful than those of many other places, as the vigour and size of our trees, their exceptionally healthy appearance, their dark foliage, and the heavy crop of high-class fruit that they bear, are at once evident to a stranger who has never seen the orange grown under such favourable conditions as are experienced here. The yield is often so heavy that the trees actually bend to the ground with the weight of their fruit, and a stack of props has to be used to prevent the tree from splitting into pieces. Those who have seen the enormous crops of apples that are produced on some trees in Tasmania or the old cider orchards of Devon or Somerset can form an idea of the crops; but the writer, who has seen both, as well as our Queensland trees, has no hesitation in saying that a Queensland mandarin can give points to either as a heavy cropper; in fact, if it has a fault, it is its proneness to overbear, particularly when young. This all tends to prove how well adapted Queensland is to the growth of citrus fruits, and were I asked to select a country particularly suited to their culture I should have no hesitation in naming this State, as I know of nowhere where their culture can be carried out with less trouble, or where the trees will produce better fruit or heavier crops. Queensland may well be termed the home of citrus fruits, as we have no less than three native species which are indigenous to the State, and are by no means uncommon in our scrubs. Their presence gives unmistakable proof of the suitability of this State for the culture of fruits of the same family, so that I think a short description of these native species may not be out of place, but will be of some interest to my readers.

Citrus australis, the native orange or lime, is both the largest and most common. It grows into a large tree, having a diameter of 15 to 18 inches in the trunk, and a height of 60 feet or more. It produces a quantity of thick-skinned acid fruit, of from 2 to 3 inches in diameter. The skin is full of a resinous sap, and the fruit is of little value. It is a slow-growing tree, though, as just mentioned, it attains a considerable size, is very hardy, and produces a quantity of fruit. Its slow growth, when young, has prevented its use as a stock on which to work improved varieties, but I have no doubt it would make a very hardy stock that would be distinctly disease-resistant.
The second variety is Citrus australasica, the so-called finger lime, a thorny bush, producing a fruit of from ¾ to 1 inch in diameter, and 3 to 4 inches long. The fruit has a thin skin, and contains an agreeable acid pulp that varies in colour, in some specimens being of a reddish tinge that resembles the pulp of a blood orange. These two varieties are met with in the Southern part of the State, but the third is a Northern species, to which Mr. F. M. Bailey, our Colonial Botanist, has given the name of Citrus inodora, the North Queensland lime. It is met with in the scrubs of the Russell River, and is described by Mr. Bailey as bearing a greater resemblance to the cultivated species than the two former varieties. It produces a fruit over 2 inches long by 1¼ inches in diameter, having a thin rind and a juicy pulp of a sharply acid flavour, so that even in its wild state it is a desirable fruit, and takes the place of the cultivated lemon. Where native species flourish as they do here, there is every probability of cultivated species thriving equally well, and this is found to be the case in practice.
