Botany: flower with two whorls of three tepals, colourful, no spots on tepals; necatries, phytomelan; 6 stamens; sword-like leaves parallel to the stem, basal rosette.
In past classifications Asparagales were mostly included in Liliales. In the Apg classifications the Asparagales were split off from Liliales and became the bigger Order. This is the more so as the Orchidales were incorporated in Asparagales too.
In the Plant theory the Asparagales are treated as one Order as in the Apg3 classification, except that Orchidaceae are split off from them to form their own Order Orchidales.
The grouping in Families is a bit different from that in the Apg3 classification. The differences can be seen in the table below. The most important difference being the splitting of Apsaragaceae in 3 Families.
1. Iridaceae: they feel that they have to get a place in the family and friends.
2. Hypoxidaceae: they have a place but have to fight for it, or get overwhelmed in it.
3. Hyacinthaceae, Themidaceae, Aphyllanthaceae: they have a place in family and friends but it is unsure, they get confused what to do, their own impulse or that of others.
4. Asparagaceae, Ruscaceae, Laxmanniaceae: they feel central in the family and friends, which give them safety but also responsibility for it.
5. Agavaceae: they have their place, do a lot but feel limited by it, there should be more.
6. Amaryllidaceae, including Alliaceae, Agapanthaceae: they feel part of the family but think about leaving as it does not give them enough love and respect.
7. Xanthorhoeaceae, including Asphodelaceae, Hemerocallidaceae: losing their place with family, friends and self-worth, everything can collapse.
2. Hypoxidaceae, Asteliaceae, Blandfordiaceae, Boryaceae, Lanariaceae, Cyanastraceae, Doryanthaceae, Xeronemataceae, Ixioliriaceae, Tecophilaeaceae are taken together. They are small families and early diverging lineages in Asparagales. Together they are not monophyletic.
3. Hyacinthaceae, Themidaceae, Aphyllanthaceae.
4. Asparagaceae, Ruscaceae, Laxmanniaceae: a monophyletic group, part of Asparagaceae in Apg3.
5. Agavaceae: part of Asparagaceae in Apg3.
6. Amaryllidaceae, including Alliaceae, Agapanthaceae: a monophyletic group.
7. Xanthorhoeaceae, including Asphodelaceae, Hemerocallidaceae: a monophyletic group.
