RICHARDIA, a small genus of the nat. ord. Araceae, native in South Africa, to which the “ arum lily ” belongs. They are all greenhouse herbaceous plants of handsome appearance, with thick underground stems and large, more or less fleshy, long-stalked, arrow-shaped leaves and white or yellow flower spathes. They are readily propagated by division of the shoot, also by seed. Water should be given abundantly at all times, and the soil for potting should be rich and retentive. Potting is best effected in spring, and from the end of June to the end of August they should be plunged in a sunny spot out of doors. They will not withstand frost, and should be wintered in a warm greenhouse. They flower throughout the year.
