LAUREL . At least four shrubs or small trees are called by this name in See also:Great See also:Britain, viz. the See also:common or See also:cherry laurel (Prunus Laurocerasus), the See also:Portugal laurel (P. lusitanica), the See also:bay or sweet laurel (Laurus nobilis) and the spurge laurel (See also:Daphne Laureola). The first two belong to the See also:rose See also:family (See also:Rosaceae), to the See also:section Cerasus (to which also belongs the cherry) of the genus Prunus.
The common laurel is a native of the woody and sub-alpine regions of the See also:Caucasus, of the mountains of See also:northern See also:Persia, of See also:north-western See also:Asia See also:Minor and of the See also:Crimea. It was received into See also:Europe in 1576, and flowered for the first See also:time in 1583. See also:Ray in 1688 relates that it was first brought from Trebizonde to See also:Constantinople, thence to See also:Italy, See also:France, See also:Germany and See also:England. See also:Parkinson in his Paradisus records it as growing in a See also:garden at See also:Highgate in 1629; and in See also: The first See also:case occurred in 1731, which induced a careful investigation to be made of its nature; See also:Schrader in 1802 discovered it to contain hydrocyanic acid. The effects of the distilled laurel-leaf water on living vegetables is to destroy them like See also:ordinary prussic acid; while a few drops See also:act on animals as a powerful poison. It was introduced into the See also:British See also:pharmacopoeia in 1839, but is generally superseded by the use of prussic acid. The aqua laurocerasi, or cherry laurel water, is now standardized to contain o.1%, of hydrocyanic acid. It must not be given in doses larger than 2 drachms. It contains benzole See also:hydrate, which is antiseptic, and is therefore suitable for hypodermic injection; but the See also:drug is of inconsistent strength, owing to the volatility of prussic acid. The following varieties of the common laurel are in cultivation: the Caucasian (Prunus Laurocerasus, See also:var. caucasica), which is hardier and bears very See also:rich dark-See also:green glossy foliage; the See also:Versailles laurel (var. latifolia), which has larger leaves; the Colchican (var. colchica), which is a See also:dwarf-spreading See also:bush with narrow sharply serrated See also:pale-green leaves. There is also the variety rotundifolia with See also:short broad leaves, the Grecian with narrow leaves and the Alexandrian with very small leaves. The Portugal laurel is a native of Portugal and See also:Madeira. It was introduced into England about the See also:year 1648, when it was cultivated in the See also:Oxford Botanic Gardens. During the first See also:half of the 18th See also:century this plant, the common laurel and the See also:holly were almost the only See also:hardy See also:evergreen shrubs procurable in British nurseries. They are all three See also:tender about See also:Paris, and consequently much less seen in the neighbourhood of that citythan in England, where they stand the ordinary winters but not very severe ones. There is a variety (myrtifolia) of compact See also:habit with smaller narrow leaves, also a variegated variety.
The evergreen glossy foliage of the common and Portugal laurels render them well adapted for shrubberies, while the racemes of See also: The date of its introduction is unknown, but must have been previous to 1562, as it is mentioned in See also:Turner's Herbal published in that year. A full description also occurs in Gerard's Herball (1597, p. 1222). It was used for strewing the floors of houses of distinguished persons in the reign of See also: The relation of Apollo to the laurel was expressed in the legend of Daphne (q.v.). The victors in the Pythian See also:games were crowned with the laurels of Apollo, and thus the laurel became the symbol of See also:triumph in See also:Rome as well as in Greece. As Apollo was the god of poets, the Laurea See also:Apollinaris naturally belonged to poetic merit (see See also:LAUREATE). The various prerogatives of the laurel among the ancients are collected by See also:Pliny (Hist. Nat. xv. 30). It was a sign of truce, like the See also:olive See also:branch; letters announcing victory and the arms of the victorious soldiery were garnished with it; it was thought that See also:lightning could not strike it, and the See also:emperor Tiberius always wore a laurel See also:wreath during See also:thunder-storms. From its association with the divine power of purification and See also:protection, it was often set before the See also:door of Greek houses, and among the See also:Romans it was the See also:guardian of the See also:gates of the Caesars (See also:Ovid, Met. i. 562 sq.). The laurel worn by See also:Augustus and his successors had a miraculous See also:history: the laurel See also: It was employed in See also:divination; the crackling of its leaves in the sacred See also:flame was a See also:good See also:omen (Tibull. ii. 5. 81), and their silence unlucky (Propert. ii. 21); and the leaves when chewed excited a prophetic afflatus (3acbvl74ayoi, cf. Tibull. ii. 5. 63). There is a poem enumerating the See also:ancient virtues of the laurel by J. Passeratius (1594). The last of the See also:plants mentioned above under the name of laurel is the so-called spurge laurel (Daphne Laureola). This and one other See also:species (D. Mezereum), the mezereon, are the See also:sole representatives of the family Thymelaeaceae in Great Britain. The spurge laurel is a small evergreen shrub, with alternate somewhat lanceolate leaves with entire margins. The green flowers are produced in early See also:spring, and See also:form drooping clusters at the base of the leaves. The calyx is four-cleft, and carries eight stamens in two circles of four each within the See also:tube. The See also:pistil forms a berry, green at first, but finally See also:black. The mezereon differs in blossoming before the leaves are produced, while the flowers are See also:lilac instead of green. The bark furnishes the drug Cortex Mezerei, for which that of the spurge laurel is often substituted. Both are powerfully acrid, but the latter is less so than the bark of mezereon. It is now only used as an ingredient of the liquor sarsae compositus concentratus. Of other species in cultivation there are D. Fortunei from See also:China, which has lilac flowers; D. pontica, a native of Asia Minor; D. alpina, from the See also:Italian See also:Alps; D. collina, See also:south See also:European; and D. Cneorum, the See also:garland See also:flower or trailing daphne, the handsomest of the hardy species. See Hemsley's Handbook of Hardy Trees, &'c.
