title: Liliidae
text: 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.
  
  Liliidae in Takhtajan system
  The Takhtajan system treats this as one of six subclasses within class Liliopsida (= monocotyledons). This subclass consists of:
   subclass Liliidae
   superorder Lilianae
   order Melanthiales
   order Colchicales
   order Trilliales
   order Liliales
   order Alstroemeriales
   order Iridales
   order Tecophilaeales
   order Burmanniales
   order Hypoxidales
   order Orchidales
   order Amaryllidales
   order Asparagales
   order Xanthorrhoeales
   order Hanguanales
   superorder Dioscoreanae
   order Stemonales
   order Smilacales
   order Dioscoreales
   order Taccales
  
  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.
