This family contains 50 genera and about 870 species. In older texts, this family is lumped with the Liliaceae. Others split this family which can be differentiated by the fact that the flowers arise in umbels. Many are popular ornamentals, including the diverse spider lilies and crinum lilies. Daffodils (Narcisus sp.) are also amaryllids.
Systematics: Differentiated from other Liliaceae relatives because the inflorescence usually raises in an umbelloid cyme. In addition, the seed coat usually has a black or blue crust. The ovary is inferior. These factors are very important in differentiation.
Similar with other Liliaceae, they have 6 petaloid tepals, 6 stamens. Leaves are alternate, basal, simple and sheathing. Fruits are most often in either capsules or berries.
