The Amaryllidaceae are a family of herbaceous, perennial and bulbous 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.
Plants have rather fleshy and two-ranked leaves and flowers typically arranged in umbels at the apex of leafless flowering stems, or scapes. The Agapanthoideae have superior ovaries, as do the Allioideae, the onion subfamily. The Allioideae produce allyl sulfide compounds which give them their characteristic smell. The Amaryllidoideae have inferior ovaries.
The history of this family can be traced back to Linnaeus' Hexandria monogynia (1753) although not formally named as such till 1805, by Jean Henri Jaume Saint-Hilaire who used the term 'Amaryllideae',. and then 'Amaryllidaceae' by John Lindley in 1836. The Lilinnaen grouping contained 51 genera which over the course of time have been variously classified either liliaceous or amaryllidaceous. This uncertainty of circumscription reflected a wider problem with the petaloid monocots in general. over the course of time there have been widely differing views as to the limits of the family, and consequently much of the literature dealing with this family requires careful inspection to determine which sense of the Amaryllidaceae the work treats. At one stage in recent history the Amaryllidaceae were joined together with the Liliaceae (e.g. Cronquist 1988 and Thorne 1976) included Amaryllidaceae within broad concepts of Liliaceae.
A wide variety of suprageneric classifications existed within the Amaryllidaceae, for instance Hickey and Clive (1997) describe ten tribes by which the family were divided, such as the Zephyrantheae.
The most recent APG classification (APG III of 2009) takes a broad view of the Amaryllidaceae, which then has three subfamilies, the Agapanthoideae (the old Agapanthaceae family), the Allioideae (the old Alliaceae family) and the Amaryllidoideae (the old Amaryllidaceae family). With this definition, the family includes about 75 genera and 1600 species.
