Alaternus.—Figured in Mill. Icon., t. 16. fig. 2. This variety is so distinct, that it is by many authors considered as a species. There are two subvarieties of it, the gold-striped-leaved, and the silverstriped-leaved. They are all of remarkably free growth, more
especially R. A. angustifolia. Geography, History, fc. The alaternus is a densely branched shrub, growing to the height of 15 ft. or 20 ft. in sheltered situations, but always preserving the character of a bush, unless carefully trained to a single stem. The leaves are alternate, shining, and often glandular at the base, and serrated in some varieties, but entire in others. The flowers are numerous, male or female, or imperfect hermaphrodites, on the same or different individuals; and hence the plant is seldom seen in England bearing fruit. It is abundant in the south of Europe, and was observed by Sir James Smith, in Italy, sometimes only a foot or two in height, and at others as high as a low tree. Evelyn, also, observed it there; and says that its blossoms, which are produced from April to June, afford an early and marvellous relief to bees.” Evelyn boasts that he was the first who brought the alaternus into use and reputation in England, and that he had propagated it from Cornwall to Cumberland. Parkinson, however, first introduced it; and he commends it for the beauty and verdure of the leaves, “abiding quite fresh all the year.” In his time it was called evergreen privet. The plant is mentioned by Pliny and by Dioscorides, both as medicinal and as being used in dyeing. Clusius states that in Portugal the bark is used to dye a red, and the wood to dye a blackish blue. In British gardens, this shrub is particularly valuable for the rapidity of its growth in almost any soil and situation, more especially the narrow-leaved variety. About the end of the seventeenth century, it was one of the few evergreens generally planted, not only for hedges and to conceal objects, but to clothe walls, and to be clipped into artificial shapes. In London and Wise's Retired Gardener, published in 1706, it is recommended to grow the alaternus in cases (boxes), for ornamenting gardens and court-yards; and, when clipped into the form of a bowl or ball, for placing in the borders of parterres. “You give it what shape you think fit by the help of your shears, which, being well guided, will make this shrub of a very agreeable figure.” (Ret. Gard.,
ii. p. 751.) The four large, round, and smoothly clipped plants of phillyrea, on naked stems, mentioned in p. 45. as possessed by Evelyn at Says Court, were doubtless of this species, and not of the genus Phillyrea, which is of much slower and less robust growth. The Alatérnus was at that time, and even so late as the time of Miller, frequently confounded with the Phillyrea; but the two genera are readily distinguished by the position of their leaves, which are alternate in Rhamnus, and opposite in Phillyrea. At present, the alaternus is chiefly planted in town gardens, to conceal walls, and because it is less injured by the smoke of coal than most other evergreens. The species, and all the varieties, are readily propagated by cuttings, which are taken off in autumn, and planted in sandy soil, in a shady border, and covered with a hand-glass. Price, in the London nurseries, of the species, and of the blotched-leaved variety, 9d. a plant; of the gold and silver-edged-leaved, 28. 6d. each : at Bollwyller, the species and varieties from 1 franc to 2 francs a plant: at New York,!. As the roots are not very productive of fibres, when large plants are chosen, they should be such as have been reared in pots, in order that they may receive no check from removal.

Description, History, fc. A deciduous shrub or low tree, growing to the height of 12 ft. or 15 ft. in
193 a state of cultivation, with many irregular branches, the young shoots of which have a smooth greyish brown bark; but the older branches have rougher bark, armed with a few short thorns. The leaves are ribbed, smooth, and of a bright green. The flowers are of a yellowish green, and they are succeeded by berries, which are globular, bluish black, nauseous, violently purgative, with 4 cells, and as many seeds. By this last character they are distinguished by druggists from the berries of R. Frángula, which are supposed to be less cathartic. In Britain, this species is found in native woods and thickets, generally on calcareous and loamy soils, but seldom above 10 ft. or 12 ft. in height. According to Pallas, this species is common in the champaign and southern parts of Siberia, with a trunk thicker than a man's arm, and the wood very hard, and of a reddish colour. The flowers are, for the most part, hermaphrodite, and, in a wild state, clustered; but in a state of cultivation they are fewer, and nearly solitary. The juice of the unripe berries has the colour of saffron, and it is used for staining maps or paper: they are sold under the name of French berries. The juice of the ripe berries, mixed with alum, is the sap green of painters; but, if the berries be gathered late in the autumn, the juice is purple. The bark affords a beautiful yellow dye. The inner bark, like that of the elder, is said to be a strong cathartic, and to excite vomiting; the berries are also strongly purgative; and it is said that the flesh of birds which feed upon them possesses the same quality. Plants of this species, in the garden of the London Horticultural Society, have attained the height of 9 ft. in 10 years : they do not make much show in spring, when in flower; but in autumn and winter, when profusely covered with their black berries, they are very ornamental. The fruit remains on after the leaves have fallen. Plants, in the London nurseries, are 1s. each ; at New York, plants are 37} cents each,
If plants were required for forming hedges (for which the species is very eligible, in consequence of its robust and rigid habit of growth), they could, no doubt, be provided and supplied at a price less than that of plants of the common hawthorn, because plants of R. cathárticus come up in the first year from the sowing.

The berries are supposed to be used for the same purposes as those of R. infectòrius, and R. tinctòrius, for which they are often sold. Neither this nor the preceding species can be considered as ornamental in itself; but both are well adapted for planting among rocks, either natural or artificial. In garden scenery, where natural rocks occur, and where it is desirable that they should be retained, the only legitimate mode of rendering them gardenesque is, by clothing them, or varying them with showy flowering plants, ligneous or herbaceous.

A deciduous shrub, growing to the height of 3 ft., in the fissures of rocks, in Sicily, Mauritania, Spain, and Greece. Introduced in 1752. In Loddiges's Catalogue, it is in the list of green-house plants; but it is generally understood to be quite hardy. Though the species of the Rhamnus are numerous, yet, as few of them attain a large size, they will not occupy so much space in an arboretum as might, at first sight, be imagined. Where the soil is dry, and the surface somewhat undulated, the plants may be scattered over it at the same distances from each other as their heights; or, if there is space to spare, at double this distance, which will allow each species to display its natural form, and to bring its leaves, flowers, and fruit to maturity. Where the soil is not naturally dry, an arti. ficial ridge of dry soil, mixed with rocks or stones, may be formed; and along this the different species of Rhamnus may
202 be scattered,

(Don's Mill., ii. p. 31.) A shrub, growing to the height of 3 ft., a native of Numidia, and introduced in 1820. According to Desfontaines, it is only a variety of R. oleöides ; but, whether a species or variety, it is, at all events, a very distinct and a very neat form : indeed, it may be observed of the species of deci. duous Rhamnus generally, that they are all characterised by a par. ticular kind of distinctness and permanence of appearance; from which, however much many of the sorts may resemble each other, yet they can never be mistaken for species belonging to other genera. They almost all grow slowly, and have wood of a hard and durable nature; and the appearance of all of them, whether as bushes or low trees, has the expression of durability. The blossoms are small, and so are the fruit; but both, or at all events the fruit, remain a long time on the plant, as well as the leaves, most of which are pointed and coriaceous, and strongly veined or ribbed ; all which adds to that expression of firmness, rigidity, and permanence in the plant, which we have already mentioned.
