Species: J. sambac
Taxonomy and nomenclature
Jasminum sambac is classified under the genus Jasminum under the tribe Jasmineae. It belongs to the olive family Oleaceae.
Despite the English common name of "Arabian jasmine", Jasminum sambac is not originally native to Arabia. The habits of Jasminum sambac support a native habitat of humid tropical climates and not the arid climates of the Middle East. Early Chinese records of the plant points to the origin of Jasminum sambac as eastern South Asia and Southeast Asia. Jasminum sambac (and nine other species of the genus) were spread into Arabia and Persia by man, where they were cultivated in gardens. From there, they were introduced to Europe where they were grown as ornamentals and were known under the common name "sambac" in the 18th century.
Medieval Arabic "zanbaq" meant jasmine flower-oil from the flowers of any species of jasmine. This word entered late medieval Latin as "sambacus" and "zambacca" with the same meaning as the Arabic, and then in post-medieval Latin plant taxonomy the word was adopted as a label for the J. sambac species. The J. sambac species is a good source for jasmine flower-oil in terms of the quality of the fragrance and it continues to be cultivated for this purpose for the perfume industry today. The Jasminum officinale species is also cultivated for the same purpose, and probably to a greater extent.
In 1753, Carl Linnaeus first described the plant as Nyctanthes sambac in the first edition of his famous book Systema Naturae. In 1789, William Aiton reclassified the plant to the genus Jasminum. He also coined the common English name of "Arabian jasmine", cementing the misconception that it was Arabian in origin.
Jasminum sambac is a species of jasmine native to a small region in the eastern Himalayas in Bhutan and neighbouring India. It is cultivated in many places, especially across much of South and Southeast Asia. It is naturalised in many scattered locales: Mauritius, Madagascar, the Maldives, Cambodia, Java, Christmas Island, Chiapas, Central America, southern Florida, the Bahamas, Cuba, Hispaniola, Jamaica, Puerto Rico, and the Lesser Antilles.
Jasminum sambac is a small shrub or vine growing up to 0.5 to 3 m (1.6 to 9.8 ft) in height. It is widely cultivated for its attractive and sweetly fragrant flowers. The flowers are also used for perfumes and for making tea. It is known as the Arabian jasmine in English. It is the national flower of the Philippines, where it is known as sampaguita. It is also one of the three national flowers of Indonesia, where it is known as melati putih.
Jasminum sambac is an evergreen vine or shrub reaching up to 0.5 to 3 m (1.6 to 9.8 ft) tall. The species is highly variable, possibly a result of spontaneous mutation, natural hybridization, and autopolyploidy. Cultivated Jasminum sambac generally do not bear seeds and the plant is reproduced solely by cuttings, layering, marcotting, and other methods of asexual propagation.
The leaves are ovate, 4 to 12.5 cm (1.6 to 4.9 in) long and 2 to 7.5 cm (0.79 to 2.95 in) wide. The phyllotaxy is opposite or in whorls of three, simple (not pinnate, like most other jasmines). They are smooth (glabrous) except for a few hairs at the venation on the base of the leaf.
The flowers bloom all throughout the year and are produced in clusters of 3 to 12 together at the ends of branches. They are strongly scented, with a white corolla 2 to 3 cm (0.79 to 1.18 in) in diameter with 5 to 9 lobes. The flowers open at night (usually around 6 to 8 in the evening), and close in the morning, a span of 12 to 20 hours. The fruit is a purple to black
berry 1 cm (0.39 in) in diameter.
