1. The officinale, or Common White Jasmine, with shrubby, slen-der,long stalks and branches, which grow, when supported, to the height of 15 or 20 feet : it has numerous white flowers, that blow at the extremities or points, and emit a very agreeable odour, especially in the evening. - The Italians prepare a fragrant oil from these flowers, by the following easy process: Cottonwool is previously soaked in bon-duc-oil (Oleum Behen), which possesses no flavour whatever; a thin layer of such cotton is then placed in a glass vessel, and a stratum of flowers over it; another parcel of cotton is spread over the latter, and this alternate stratification repeated every day, till the oil is completely saturated with the grateful odour of jessamine; when the whole is carefully expressed. It is worthy of notice, that neither spirits nor water will combine with this favourite perfume; and that there is no other method of fixing it than by means of vegetable oils.
2. The fruticans, or Shrubby Jasmine, which has long, shrubby, nailing stales and branches, on the sides and ends of which appear yellow flowers, in the month of June. This species is remarkable for the numerous suckers which spring from its roots, and overspread the adjoining ground, if they be not annually taken up : its branches and leaves impart a fine citron colour to cloth previously immersed in alum-water; but solutions of tin and bismuth produce a much brighter shade.
3. The humile, or Dwarf Yellow Jasmine, has firm stalks, low bushy branches, and produces yellow flowers in the month of July. The whole plant yields a fine olive colour, if the wool or cloth be first prepared in a solution of green vitriol.
All these species thrive in our gardens, and are easily propagated by layers and cuttings; but they require a warm, and rather humid, soil. Beautiful shrubs may be produced, by inoculating the first species with that called grandiflorum, or the Great-flowered Catalonian Jasmine.
