Eight species. Stove plants, evergreen, herbaceous, and annual. Seed or cuttings. Sandy loam and peat.

L. Russellianus is a half-hardy biennial. Mr. Cuthill, of Denmark Hill, near London, is its most successful cultivator; and the directions given by him, with some other suggestions, arc as follow: -

Sow the first week of March in a forty-eight pot. Fill the pot very firmly with a compost of loam, and leaf-mould or peat, in equal proportions, mixed with a little sand; over the compost put half an inch in depth of damp sand, and on this, being first pressed fiat, the seed is to be sown, and covered with a little dry river-sand. Cover the top of the pot with a piece of glass, and keep in a temperature of 70°. Never water on the top, but keep in a pan constantly supplied with water. When the seedlings are three weeks old, prick out singly into sixties: the compost as before, with plenty of drainage. When established give water abundantly, both in the pans and over the foliage, and keep in a temperature of about SO0. In August top them at every joint, and six weeks after shift into forty-eights. Give water now only in pans - for the surface of the earth must be kept dry - once a fortnight in dry weather, else once a month; and retain the plants through the winter in a temperature between 50° and 60°. As February closes remove them to a temperature of about 75°, moving them, as soon as vegetation is renewed, into eights.

They now require a high temperature, about 80° or 85°, abundance of water, and some liquid-manure. If kept in a pit during the winter, they must not at first, when moved into a house, be exposed to the sun's rays. They will bloom in July, and continue in flower two or three months, if supplied abundantly with water or liquid manure. Dryness of soil occasions a speedy fall of the blossoms. - Johnson's Gardener's Almanack.
