The Amaryllidaceae are perennial herbs from a bulb with contractile roots, comprising 50 genera and 870 species. The leaves are alternate and more or less basal, simple, usually linear or lorate, flat, entire, parallel-veined, sheathing at base; stipules absent. The flowers are bisexual, often showy, actinomorphic to zygomorphic, usually in umbelloid cymes. The perianth consists of 6 distinct or connate petaloid tepals, sometimes with an adnate corona. The androecium consists of 6 stamens attached to the receptacle or adnate to the perianth tube; filaments free or connate, sometimes appendaged and forming a staminal corona. The gynoecium consists of a single compound pistil of 3 carpels, a single style, one capitate or 3-lobed stigma, and an inferior ovary with 3 locules, each containing several to numerous axile ovules. The fruit is a loculicidal capsule or sometimes a berry. The seed coat usually has a black or blue crust.

||Crinum amabile, giant spider lily. These flowers have a very long, narrow perianth tube or epigynous zone that arises from the summit of the inferior ovary.|
||Crinum asiaticum, grand crinum. These flowers have a very long, narrow perianth tube or epigynous zone that arises from the summit of the inferior ovary.|
||Eucharis sp. Note the inferior ovary, umbellate inflorescence, and the crown formed by the androecium.|
|Hippeastrum cf. punicium, note inferior ovary and umbellate inflorescence.|
|Hippeastrum sp. The two plants with red-margined white flowers in the first photo are probably H. reticulatum. The others are probably hybrids.|

||Hymenocallis littoralis, spider lily.|
|Phaedranassa sp. Note strong zygomorphy of the flowers, an uncommon trait in the family.|
