Everything about Asparagales totally explained
Asparagales is an
order of
flowering plants. The order must include the family
Asparagaceae, but other families included in the order have varied markedly between different classifications.
APG II system
The
APG II system of 2003, places the order in the clade
monocots and uses the following circumscription:
Note: "+ ..." = optional segregrate family, that may be split off from the preceding family.
APG II has consolidated some of the families in the earlier
APG system, while recognizing an alternative, that allows smaller families to be seggregated and still follow the 'APG system'. Under the new classification system a taxonomist could, for example, correctly choose to include the daylilies (
Hemerocallis) in family
Hemerocallidaceae, or in family
Xanthorrhoeaceae.
APG system (1998)
The
APG system of 1998 also placed the order in the clade
monocots but used this circumscription:

Dahlgren system
The Dahlgren system placed the order in superorder Lilianae in subclass Liliidae [=monocotyledons] of class Magnoliopsida [=angiosperms] and used this circumscription:
order Asparagales
:family Agavaceae
:family Alliaceae
:family Amaryllidaceae
:family Anthericaceae
:family Aphyllanthaceae
:family Asparagaceae
:family Asphodelaceae
:family Asteliaceae
:family Blandfordiaceae
:family Calectasiaceae
:family Convallariaceae
:family Cyanastraceae
:family Dasypogonaceae
:family Doryanthaceae
:family Dracaenaceae
:family Eriospermaceae
:family Hemerocallidaceae
:family Herreriaceae
:family Hostaceae
:family Hyacinthaceae
:family Hypoxidaceae
:family Ixioliriaceae
:family Lanariaceae
:family Luzuriagaceae
:family Nolinaceae
:family Philesiaceae
:family Phormiaceae
:family Ruscaceae
:family Tecophilaeaceae
:family Xanthorrhoeaceae
Other systems
The Cronquist system didn't recognise the order, and placed many of the plants involved in order Liliales (in subclass Liliidae in class Liliopsida [=monocotyledons]). Some genera were even included in family Liliaceae.
The Wettstein system, last revision of 1935, didn't recognise such an order, and placed many of the plants involved in order Liliiflorae in class Monocotyledones.
