Rh of the best known and most highly esteemed of British hardy ligneous climbers, is a native of northern India and Persia, introduced about the middle of the 16th century. In the centre and south of Europe it is thoroughly acclimatized. Although it grows to the height of 12 and sometimes 20 ft., its stem is feeble and requires support; its leaves are opposite, pinnate and dark green, the leaflets are in three pairs, with an odd one, and are pointed, the terminal one larger and with a tapering point. The fragrant white flowers bloom from June to October; and, as they are found chiefly on the young shoots, the plant should only be pruned in the autumn. Varieties with golden and silver-edged leaves and one with double flowers are known.

The zambak or Arabian jasmine, J. Sambac, is an evergreen white-flowered climber, 6 or 8 ft. high, introduced into Britain in the latter part of the 17th century. Two varieties introduced somewhat later are respectively 3-leaved and double-flowered, and these, as well as that with normal flowers, bloom throughout the greater part of the year. On account of their exquisite fragrance the flowers are highly esteemed in the East, and are frequently referred to by the Persian and Arabian poets. An oil obtained by boiling the leaves is used to anoint the head for complaints of the eye, and an oil obtained from the roots is used medicinally to arrest the secretion of milk. The flowers of one of the double varieties are held sacred to Vishnu, and used as votive offerings in Hindu religious ceremonies. The Spanish, or Catalonian jasmine, J. grandiflorum, a native of the north-west Himalaya, and cultivated both in the old and new world, is very like J. officinale, but differs in the size of the leaflets; the branches are shorter and stouter, and the flowers very much larger, and reddish underneath. By grafting it on two-year-old plants of J. officinale, an erect bush about 3 ft. high is obtained, requiring no supports. In this way it is very extensively cultivated at Cannes and Grasse, in the south of France; the plants are set in rows, fully exposed to the sun; they come into full bearing the second year after grafting; the blossoms, which are very large and intensely fragrant, are produced from July till the end of October, but those of August and September are the most odoriferous.

The aroma is extracted by the process known as enfleurage, i.e. absorption by a fatty body, such as purified lard or olive oil. Square glass trays framed with wood about 3 in. deep are spread over with grease about half an inch thick, in which ridges are made to facilitate absorption, and sprinkled with freshly gathered flowers, which are renewed every morning during the whole time the plant remains in blossom; the trays are piled up in stacks to prevent the evaporation of the aroma; and finally the pomade is scraped off the glass, melted at as low a temperature as possible, and strained. When oil is employed as the absorbent, coarse cotton cloths previously saturated with the finest olive oil are laid on wire-gauze frames, and repeatedly covered in the same manner with fresh flowers; they are then squeezed under a press, yielding what is termed huile antique au jasmin. Three pounds of flowers will perfume 1 ℔ of grease—this is exhausted by maceration in 1 pt. of rectified spirit to form the “extract.” An essential oil is distilled from jasmine in Tunis and Algeria, but its high price prevents its being used to any extent. The East Indian oil of jasmine is a compound largely contaminated with sandalwood-oil.

The distinguishing characters of J. odoratissimum, a native of the Canary Islands and Madeira, consist principally in the alternate, obtuse, ternate and pinnate leaves, the 3-flowered terminal peduncles and the 5-cleft yellow corolla with obtuse segments. The flowers have the advantage of retaining when dry their natural perfume, which is suggestive of a mixture of jasmine, jonquil and orange-blossom. In China J. paniculatum is cultivated as an erect shrub, known as sieu-hing-hwa; it is valued for its flowers, which are used with those of J. Sambac, in the proportion of 10 ℔ of the former to 30 ℔ of the latter, for scenting tea—40 ℔ of the mixture being required100 ℔ of tea. J. angustifolium is a beautiful evergreen climber 10 to 12 ft. high, found in the Coromandel forests, and introduced into Britain during the present century. Its leaves are of a bright shining green; its large terminal flowers are white with a faint tinge of red, fragrant and blooming throughout the year.

In Cochin China a decoction of the leaves and branches of J. nervosum is taken as a blood-purifier; and the bitter leaves of J. floribundum (called in Abyssinia habbez-zelim) mixed with kousso is considered a powerful anthelmintic, especially for tapeworm; the leaves and branches are added to some fermented liquors to increase their intoxicating quality. In Catalonia and in Turkey the wood of the jasmine is made into long, slender pipe-stems, highly prized by the Moors and Turks. Syrup of jasmine is made by placing in a jar alternate layers of the flowers and sugar, covering the whole with wet cloths and standing it in a cool place; the perfume is absorbed by the sugar, which is converted into a very palatable syrup. The important medicinal plant known in America as the “Carolina jasmine” is not a true jasmine (see ).

Other hardy species commonly cultivated in gardens are the low or Italian yellow-flowered jasmine, J. humile, an East Indian species introduced and now found wild in the south of Europe, an erect shrub 3 or 4 ft. high, with angular branches, alternate and mostly ternate leaves, blossoming from June to September; the common yellow jasmine, J. fruticans, a native of southern Europe and the Mediterranean region, a hardy evergreen shrub, 10 to 12 ft. high, with weak, slender stems requiring support, and bearing yellow, odourless flowers from spring to autumn; and J. nudiflorum (China), which bears its bright yellow flowers in winter before the leaves appear. It thrives in almost any situation and grows rapidly.

JASON ( ), in Greek legend, son of Aeson, king of Iolcus in Thessaly. He was the leader of the Argonautic expedition (see ). After he returned from it he lived at Corinth with his wife (q.v.) for many years. At last he put away Medea, in order to marry Glauce (or Creusa), daughter of the Corinthian king Creon. To avenge herself, Medea presented the new bride with a robe and head-dress, by whose magic properties the wearer was burnt to death, and slew her children by Jason with her own hand. A later story represents Jason as reconciled to Medea (Justin, xlii. 2). His death was said to have been due to suicide through grief, caused by Medea’s vengeance (Diod. Sic. iv. 55); or he was crushed by the fall of the poop of the ship “Argo,” under which, on the advice of Medea, he had laid himself down to sleep (argument of Euripides’ Medea). The name (more correctly Iason) means “healer,” and Jason is possibly a local hero of Iolcus to whom healing powers were attributed. The ancients regarded him as the oldest navigator, and the patron of navigation. By the moderns he has been variously explained as a solar deity; a god of summer; a god of storm; a god of rain, who carries off the rain-giving cloud (the golden fleece) to refresh the earth after a long period of drought. Some regard the legend as a chthonian myth, Aea (Colchis) being the under-world in the Aeolic religious system from which Jason liberates himself and his betrothed; others, in view of certain resemblances between the story of Jason and that of Cadmus (the ploughing of the field, the sowing of the dragon’s teeth, the fight with the Sparti, who are finally set fighting with one another by a stone hurled into their midst), associate both with Demeter the corn-goddess, and refer certain episodes to practices in use at country festivals, e.g. the stone throwing, which, like the  at the Eleusinia and the  at
