This is the only genus of the order coming within our province. It is characterised by having a succulent fruit. The species occur in Europe, Asia, Africa, South America, and Australia; and the name is an altered form of an Arabic word signifying fragrant.

1. J. officinale. Common White Jessamine. - This beautiful plant is deservedly a great favourite, though not so universally planted as it should be. Branches angular, slender, and flexible, deep green. Leaves opposite, deciduous, pinnate; leaflets lanceolate, acuminate. Flowers white, very fragrant, produced from June till September. A native of Northern India and China, and now naturalised in the South of Europe. There are variegated and double-flowered varieties, but none superior to the common one.

2. J. fruticans. - An evergreen more erect-growing species with alternate trifoliolate or unifoliolate dark green shining leaves and yellow flowers appearing in July or August. South of Europe.

3. J. humile. - Another South European species near the last, but of smaller stature and humbler growth. Leaflets three or more, ovate-oblong, acute. Flowers yellow, in Summer.

4. J. nudiflorum (fig. 163). - This deciduous species is remarkable for its numerous solitary opposite yellow flowers which are produced throughout the length of the flexible green branches from November onwards through the Winter. Leaves small, ternate. A native of China. There is a variety with golden leaves.

5. J. revolutum. - Branches rather stouter than in most of the foregoing. Leaves persistent, pinnate, alternate, of a dark glossy green. Flowers fragrant, bright yellow, borne in large terminal clusters. A native of Northern India, blooming all the Summer.

J. Wallichianum, J. pubigerum, and J. heterophyllum are yellow-flowered North Indian species less frequently seen; the latter is remarkable for the large size of its trifoliolate leaves, which are often reduced to one leaflet. J. Azoricum and J. odoratissimum are white-flowered species from the Atlantic Islands. All of these are more or less tender.
