Arecidae

From Wikipedia, the free encyclopedia

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.

[edit] 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)

[edit] 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

[edit] 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.
