Amaryllis (the name of a girl in classical pastoral poetry), in botany, a genus of the natural order Amaryllidaceae, containing the belladonna lily (Amaryllis Belladonna), a native of South Africa, which was introduced into cultivation at the beginning of the 18th century. This is a half-hardy bulbous plant, producing in the spring a number of strap-shaped, dull green leaves, 1-1 1/2 ft. long, arranged in two rows, and in autumn one or two solid stems, each bearing at the top a cluster of 2-12 funnel-shaped flowers. Several forms are known in cultivation. Most of the so-called Amaryllis of gardens belong to the allied genus Hippeastrum (q.v.).
