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:Johnson's edition of See also:Gerard's Herbal (1633) it is recorded that the plant " is now got into many of our choice See also:English gardens, where it is well respected for the beauty of the leaues and their lasting or continuall greennesse (see Loudon's See also:Arboretum, ii. 717). The leaves of this plant are rather large, broadly See also:lance-shaped and of a leathery consistence, the margin being somewhat serrated. They are remarkable for their poisonous properties, giving off the odour of See also:bitter almonds when bruised; the vapour thus issuing is sufficient to kill small See also:insects by the prussic See also:acid which it contains. The leaves when cut up finely and distilled yield oil of bitter almonds and hydrocyanic (prussic) acid. Sweetmeats, custards, cream, &c., are often flavoured with laurel-See also:leaf See also:water, as it imparts the same flavour as bitter almonds; but it should be used sparingly, as it is a dangerous See also:poison, having several times proved fatal.

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:white See also:flowers are not devoid of beauty. The former often ripens its insipid drupes, but the Portugal rarely does so. It appears to be less able to accommodate itself to the English See also:climate, as the See also:wood does not usually " ripen " so satisfactorily. Hence it is rather more liable to be cut by the See also:frost. It is grown in the open See also:air in the See also:southern See also:United States. The bay or sweet laurel (Laurus nobilis) belongs to the family Lauraceae, which contains sassafras, See also:benzoin, camphor and other trees remarkable for their aromatic properties. It is a large evergreen See also:shrub, sometimes reaching the height of 6o ft., but rarely assuming a truly See also:tree-like See also:character. The leaves are smaller than those of the preceding laurels, possessing an aromatic and slightly bitter flavour, and are quite devoid of the poisonous properties of the cherry laurel. The small yellowish-green flowers are produced in axillary clusters, are male or See also:female, and consist of a See also:simple 4-leaved perianth which encloses nine stamens in the male, the anthers of which dehisce by valves which lift upwards as in the common See also:barberry, and carry glandular processes at the See also:base of the filament. The See also:fruit consists of a succulent See also:berry surrounded by the persistent base of the perianth. The bay laurel is a native of Italy, See also:Greece and North See also:Africa, and is abundantly grown in the British Isles as an evergreen shrub, as it stands most winters.

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:Elizabeth. Several varieties have been cultivated, differing in the character of their foliage, as the undulata or See also:wave-leafed, salicifolia or See also:willow-leafed, the variegated, the broad-leafed and the curled; there is also the See also:double-flowered variety. The bay laurel was carried to North See also:America by the See also:early colonists. This laurel is generally held to be the Daphne of the ancients, though See also:Lindley, following Gerard (Herball, 1597, p. 761), asserted that the See also:Greek Daphne was Ruscus racemosus. Among the Greeks the laurel was sacred to See also:Apollo, especially in connexion with See also:Tempe, in whose laurel groves the See also:god himself obtained See also:purification from the See also:blood of the See also:Python. This See also:legend was dramatically represented at the Pythian festival once in eight years, a boy fleeing from See also:Delphi to Tempe, and after a time being led back with See also:song, crowned and adorned with laurel. Similar Sadivriq opiat were known elsewhere in Greece. Apollo, himself purified, was the author of purification and See also:atonement to other penitents, and the laurel was the See also:symbol of this See also:power, which came to be generally associated with his See also:person and sanctuaries.

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:grove at the imperial See also:villa by the ninth milestone on the Flaminian way sprang from a shoot sent from See also:heaven to Livia Drusilla (Sueton. See also:Galba, i.). Like the olive, the laurel was forbidden to profane use.

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.
