Bulbous herbs with umbellate flowers destitute of a corona. Perianth-tube short, lobes strongly nerved. The plants constituting this genus and Hippeastrum nearly all require more or less artificial heat in this country; but one, Amaryllis Belladonna (fig. 233), is nearly or quite hardy in the South if planted at a sufficient depth. It grows about a foot and a halt high, producing towards the end of Summer large umbels of beautiful rose-coloured flowers pencilled with crimson. The strap-shaped leaves appear after the flower-stalks have died away. This is a native of South Africa, and has been cultivated in European gardens for upwards of two centuries. The generic name is of classic origin.
