Biology:Commelinidae

Commelinidae 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 Commelinaceae. A well-known system that did use this name is the Cronquist system (1981), but it was also used by the Takhtajan system:

In the Takhtajan system

In the Takhtajan system treats this as one of six subclasses within the class Liliopsida (=monocotyledons). It consists of

• subclass Commelinidae

  superorder Bromelianae

  order Bromeliales

  order Velloziales

  superorder Pontederianae

  order Philydrales

  order Pontederiales

  order Haemodorales

  superorder Zingiberanae

  order Musales

  order Lowiales

  order Zingiberales

  order Cannales

  superorder Commelinanae

  order Commelinales

  order Mayacales

  order Xyridales

  order Rapateales

  order Eriocaulales

  superorder Hydatellanae

  order Hydatellales

  superorder Juncanae

  order Juncales

  order Cyperales

  superorder Poanae

  order Flagellariales

  order Restionales

  order Centrolepidales

  order Poales

Commelinidae in the Cronquist system

In the Cronquist system treats this as one of four subclasses within the class Liliopsida (=monocotyledons). It consists of:

• subclass Commelinidae

  order Commelinales

  order Eriocaulales

  order Restionales

  order Juncales

  order Cyperales

  order Hydatellales

  order Typhales

APG system

The APG II system does not use formal botanical names above the rank of order; most of the plants involved here are assigned to the clade commelinids in the monocots (its predecessor, the APG system used the clade commelinoids).
