::summary Subclass of flowering plants ::
Arecidae is a botanical name at the rank of subclass. Circumscription of the subclass will vary with the taxonomic system being used (there are many such systems); the only requirement being that it includes the family Arecaceae.
Arecidae in the Takhtajan system
The Takhtajan system used this name for a subclass in the class Liliopsida (=monocotyledons).
- subclass Arecidae
- : superorder Arecanae
- :: order Arecales
- ::: family Arecaceae (or Palmae)
- :: order Cyclanthales
- ::: family Cyclanthaceae
- :: order Arales
- ::: family Araceae
- ::: family Lemnaceae
- :: order Pandanales
- ::: family Pandanaceae
- :: order Typhales
- ::: family Sparganiaceae
- ::: family Typhaceae
Arecidae in the Cronquist system
The Cronquist system (1981) used this name for a subclass in the class Liliopsida (=monocotyledons), with the circumscription:
- subclass Arecidae
- : order Arecales
- :: family Arecaceae (or Palmae)
- : order Cyclanthales
- :: family Cyclanthaceae
- : order Pandanales
- :: family Pandanaceae
- : order Arales
- :: family Acoraceae
- :: family Araceae
- :: family Lemnaceae
APG II system
The APG II system does not use formal botanical names above the rank of order; it assigns the plants included in this subclass by Cronquist in various taxa throughout the clade monocots. In other words, by today's standards Cronquist's subclass was not a "good" group.
