Syn: family Amaryllidaceae, amaryllis family

The Amaryllidaceae (amaryllids), or Amaryllis family, are a family of herbaceous, mainly perennial and bulbous (rarely rhizomatous) flowering plants included in the monocot order Asparagales. The family takes its name from the genus Amaryllis, hence the common name of the amaryllis family. The leaves are usually linear, the flowers usually bisexual and symmetrical, arranged in umbels on the stem. The petals and sepals are undifferentiated as tepals, which may be fused at the base into a floral tube. Some also display a corona. Allyl sulfide compounds produce the characteristic odour of the onion subfamily (Allioideae).

The family, which was originally created in 1805, now contains about 1600 species, divided into about 75 genera, 17 tribes and three subfamilies, the Agapanthoideae (agapanthus), Allioideae ( onions and chives) and Amaryllidoideae ( amaryllis, daffodils, snowdrops). Over time it has seen much reorganisation and at various times was combined together with the related Liliaceae. Since 2009 a very broad view has prevailed based on phylogenetics, and including a number of other former families.

The family are found in tropical to subtropical areas of the world and include many ornamental garden plants and vegetables.
