# Liliidae

Liliidae 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 Liliaceae.

The Takhtajan system treats this as one of six subclasses within class Liliopsida (= monocotyledons). This subclass consists of:

* subclass Liliidae

       order Liliales
       order Alstroemeriales
       order Iridales
       order Tecophilaeales
       order Burmanniales
       order Hypoxidales
       order Orchidales
       order Amaryllidales
       order Asparagales
       order Xanthorrhoeales
       order Hanguanales

## Liliidae in Cronquist system

The Cronquist system treats this as one of five subclasses within class Liliopsida (= monocotyledons), and it consists of:

* subclass Liliidae

    order Liliales
    order Orchidales

## Liliidae in Dahlgren and Thorne systems

In the Dahlgren system and the Thorne system (1992) this is an important name: this subclass comprises the monocotyledons (in APG II these are the monocots).

### Dahlgren (1985)

* subclass Liliidae [= monocotyledons]

    superorder Alismatanae
    superorder Triuridanae
    superorder Aranae
    superorder Lilianae
    superorder Bromelianae
    superorder Zingiberanae
    superorder Commelinanae
    superorder Arecanae
    superorder Cyclanthanae
    superorder Pandananae

### Thorne (1992)

(in the version of the system as depicted by Reveal)

* subclass Liliidae [= monocotyledons ]

    superorder Lilianae
    superorder Hydatellanae
    superorder Triuridanae
    superorder Aranae
    superorder Cyclanthanae
    superorder Pandananae
    superorder Arecanae
    superorder Commelinanae

## Liliidae in APG II system

The APG and APG II systems do not use formal botanical names above the rank of order, and names such as Liliopsida and Liliidae have no place in these systems.
