Arecidae
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).
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
- family Araceae
- order Arecales
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.
