Jasminium (Arabic name, from which have come Jessamine, Jasmin and Jasminum). Oleaceae. Jasmine. Jessamine. Climbing or erect shrubs, with attractive flowers, mostly very fragrant, prized for planting in mild climates and frequently grown under glass.

Leaves opposite or alternate, pinnate but sometimes reduced to 1 lft.(petiole jointed): fls. on the ends of the branchlets, or twin, or in dichotomous cymes; corolla yellow or white, sometimes reddish, salver-shaped, the 4-9 or more lobes convolute in the bud, much exceeding the calyx; stamens 2, included in the corolla-tube; ovary 2-loculed, with 1-4 erect ovules: fr. a 2-lobed berry, or sometimes the carpels separate, the carpels mostly 2-seeded.—Probably upwards of 200 species, widely distributed in warm parts of Eu., Asia, Afr., and the Pacific region; nearly absent from Amer. The genus is closely allied to Ligustrum, but differs in the compound lvs. and twin-carpeled frs. Olea is also a related genus.

Jasmines are of diverse horticultural groups. Some of them are hardy in the middle and southern states, whereas others are winter-flowering warmhouse plants. Most of them are known as coolhouse or temperate- house shrubs, of half-climbing habit. They are all of easy culture. They propagate readily by cuttings of nearly mature wood and by layers. The species are usually called jasmines although the word jessamine is really the same. J. officinale is the jessamine of poetry. Some of them (particularly J. grandiflorum) are grown for perfume-making. The Cape jessamine is Gardenia, although there is a Jasminum capense. Yellow or Carolina jessamine is Gelsemium. The hardiest kinds are J. humile, J. fruticans, J. floridum, J. nudiflorum, J. primulinum, J. officinale, but none of them is reliable north of Washington without protection, and even then only seldom north of Philadelphia.
