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[1] used this name for a subclass in the class Liliopsida (=monocotyledons).
- subclass Arecidae
- superorder Arecanae
- order Arecales
- order Cyclanthales
- family Cyclanthaceae
- order Arales
- order Pandanales
- family Pandanaceae
- order Typhales
- family Sparganiaceae
- family Typhaceae
- superorder Arecanae
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
- order Cyclanthales
- family Cyclanthaceae
- order Pandanales
- family Pandanaceae
- order Arales
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.
