A native of Nepal at Suembu and Sirinagur, where it forms a tree from 20 ft. to 40 ft. in height, the leaves and branches of which are poisonous to goats, as is implied in the epithet capricida. It flowers in May. It was introduced in 1825, and there are plants at Messrs. Loddiges's. With a view to keep up a distinctive character between the plants kept in green-houses and hot-houses, and those grown in the open air, we do not think it advisable to multiply, in collections, exotic species of genera of which the majority are hardy, and common in gardens; but, botanically, every species is interesting. App. i. Half-hardy Species of Pieris not yet introduced. P. formosa D. Don (Don's Mill., 3. p. 832.), Andrómeda formosa Wall., is a native of Nepal, where it forms an evergreen tree, with the habit of A'rbutus or Clèthra. The leaves are lanceolate, acuminated, crenulated, and glabrous; and the flowers rose-coloured, each furnished with a small bractea at the base. This would appear to be a very desirable species; and if it were introduced, and even found only half-hardy, some new sort might be obtained from it by means of cross-fecundation with hardy freegrowing species. P. lanceolata D. Don (Don's Mill., 3. p. 382.), Andrómeda lanceolata Wall., A. squamuldsa D. Don (Prod. Fl. Nep., p. 149.), is a small-branched tree, with elliptic leaves from 3 in. to 4 in. long, and purplish corollas. P. japonica D. Don, Andrómeda japónica Thunb., and our fig. 914., is a native of Japan, with glabrous, lanceolate, crenulated leaves, and red flowers. 914 GENUS XI. PHYLLO'DOCE Sal. THE PHYLLODOCE. Lin. Syst.

The following forms of this species are given in Don's Miller, and are to be procured in the principal London nurseries. A. U. 1 álbus Ait. Hort. Kew., ii. p. 71. - Flowers white. This is the common sort, raised in nurseries by seed. The flowers are sometimes of a greenish or yellowish-white, and sometimes reddish. The colour of the fruit also varies in a similar manner. A. U. 2 ruber Ait. Hort. Kew., ii. p. 71.- Flowers reddish. This is A. U. 3 plenus Ait. Hort. Kew., ii. p. 71.- Flowers semidouble. of segments constant to the corolla of the species. A. U. 5 integrifolius. - Leaves entire. (Sims Bot. Mag., t. 2319.) A. U. 7 salicifòlius. Leaves narrow. Description, &c. The common arbutus will grow to the height of 20 ft. or 30 ft.; but, unless pruned to a single stem, it assumes more the character of a huge bush than that of a regular-headed tree. When it is pruned, however, it forms a small, picturesque-headed, evergreen tree of great beauty, at every season of the year; and particularly so in autumn, when it is covered with its white bell-shaped flowers, which are slightly tinged with pink, intermixed with its large strawberry-like fruit, which is 12 months before it arrives at perfection, and which is, therefore, seen on the tree at the same time as the flower. Smith says that the fruit is insipid, and scarcely eatable in England; but that in the Levant it is said to be much larger and more agreeable, as well as more wholesome. The reddish hue of the bark is very remarkable in this and some other species of A'rbutus. The rate of growth of the tree, when young, and properly treated, will average 1 ft. a year for the first 10 years; and the plant is of considerable durability. Geography. The arbutus is a native of the south of Europe, also of varous parts of Asia, and of Africa, about Mount Atlas and Algiers; and it is particularly abundant in Italy, in the woods of the Apennines. In France, it grows as far north as lat. 56°; but it requires protection, in the winter, in the neighbourhood of Paris. In Britain, it is one of the doubtful natives; for, though it seems to be perfectly naturalised in the south of Ireland, it is, as we have seen (p. 34.), considered by many as having been introduced there. Some of the defenders of our indigenous flora, however, feel no doubts on the subject. Mr. Babington, a writer in the Mag. Nat. Hist., says, "It has been doubted, if" A'rbutus U`nedo "is indigenous at Killarney; but I cannot conceive it possible for any person, who has observed it on the spot, to believe it to have been introduced by the monks of Mucross Abbey,' which is the theory of the sceptical. It grows in several isolated spots, far up the mountains, and is in its greatest beauty when springing from the crevices of rock on the islets of the upper lake. My conclusion is, that it is truly an aboriginal native of that country. The fruit is excellent." [!] (Vol. ix. p. 245.) Mr. J. Drummond, in Mackay's Flora Hibernica, says that it is certainly indigenous. History. The arbutus was known to the Greeks and Romans; but, according to Pliny, it was not held in much esteem; for, as the specific name implies, he adds, the fruit was considered so bitter, that only one of it could be eaten at a time. There can be no doubt, however, that it was an article of food, in the early ages, both in Greece and Italy; since in these countries, and also in Spain, as well as about Killarney, in Ireland, it is still eaten by the common people. Virgil recommends the young shoots as winter food for young goats, and as fit for basket-work. Horace praises the tree for its shade; and Ovid celebrates its loads of“ blushing fruit.' It is spoken of by Gerard as, in his time, growing only in some few gardens in England. It is mentioned by various writers, both in poetry and in prose, who have been charmed with its beauty. Among others, Mrs. Barbauld, in her poem entitled Corsica, written in 1769, gives the following description of its appearance in that island in a wild state: And Miss Twamley "While, glowing bright Beneath the various foliage, wildly spreads has the following lines on this tree in her Romance of Nature published in 1836. 1119 In the Properties and Uses. from the fruit in Spain, and a wine in Corsica: but, in Britain, the sole A sugar and a very good spirit have been extracted use of the plant is as an ornamental evergreen shrub or low tree. neighbourhood of Algiers it forms hedges; and there, in Greece, and also in Spain, the bark is used by tanners; and the charcoal made from the wood is highly valued. The wood is white, hard, and heavy, but brittle, and with little elasticity. The durability and abundance of its shining green foliage; the brownish red colour of its young shoots; the waxy and delicate ance of its flowers, which are produced in abundance, at a season when most plants are beginning to shed their leaves; and the splendour of its fruit, which, as before observed, is intermixed with the flowers, and often remains on all the winter; render it a most desirable plant. In ornamental plantations, the pink-flowered variety deserves the preference, not only on account of the beauty of its flowers, but because the young shoots and the nerves of the leaves partake of a reddish hue. appear Soil, Situation, &c. The common arbutus will thrive in any tolerably free soil; though it seems to grow fastest, and attain the largest size, in deep sandy loam. It will grow either in open or sheltered situations, but does not thrive under the shade of trees. which should be sown, as soon as they are separated from the pulp of the The species is readily propagated by seeds, fruit, in pots of light, rich, sandy soil, or heath mould, and then placed in the shade, where they can be protected from the frost and the sun. Plants raised from seed do not generally flower till 5 or 6 years old. The double, and the scarlet-flowered, and all the other varieties, are propagated by layers; or by cuttings of the wood in a growing state, taken off in July, and treated like cuttings of heath. Statistics. In the environs of London, in the arboretum at Kew, the common arbutus is 12 ft. high; and it is equally high, or higher, at a great number of places within the same distance of the metropolis. In the Mile End Nursery it is 15 ft. high, and the diameter of the head is 45 ft. In the Garden of the Horticultural Society, and in the arboretum of Messrs Loddiges, plants, 10 years planted, have attained the height of 10 ft. In Scotland, in Argyllshire, at Castle Mainard, it is 13 ft. high. In Ireland, on the lower lake of Killarney, a tree, or large bush, was 36 ft. in diameter in 1805; one at Power's Court is equally large; and a similar one existed at Newtown Mount Kennedy, but was blown down in 1804; at Morn Park, Cork, it is 32 ft. high, the diameter of the trunk 2 ft. 3 in., and of the head 23 ft. The price of plants, in the London nurseries, is from 6d. to 1s. each, according to the size, or from 11. 78. 6d. to S. 15s. per hundred; and the scarlet-flowered variety is 2s. 6d. a plant. At Bollwyller, and at New York, both the species and varieties are green-house plants. ? 2. A. HY BRIDA Ker. The hybrid Arbutus, or Strawberry Tree. Identification. Ker Bot.
