To a large extent Cronquist's subclass Asteridae corresponds with the older concepts of Sympetalae and Tubiflorae, groups that were defined by having their petals united into a tube.

Reveal's circumscription of the group corresponds largely to Cronquist's class Magnoliopsida ( but minus subclass Magnoliidae ) and to the eudicots of the APG II system minus Ranunculales and some other early-branching groups.

Cronquist's concept also corresponds closely with the APG II group of euasterids but the APG does not formally recognize a group called " Asteridae " ( or any other group above the rank of order ).

Older systems ( e. g., Arthur Cronquist's ) placed them into the Capparales, a now-defunct order that had a similar definition.

The APG II system does not use formal botanical names above the rank of order ; it assigns most of the plants involved to the ( expanded ) order Alismatales, in the clade ' monocots ', although the plants in Cronquist's order Triuridales are assigned to quite different placements.

The following classification systems acknowledge family Bignoniaceae with the same circumscription as the APG II system classification: Cronquist's system, Dahlgren's classification, Reveal's classification, Stevens's classification, Takhtajan's classification and Thorne's classification.

In Cronquist's old system ( 1981, 1988 ), as well as Takhtajan's ( 1997 ), Gunneraceae actually belonged to the Rosidae, while Myrothamnaceae belonged to the Hamamelis.

In Cronquist's classification, it included 89 genera and more than 800 living species.

The Cronquist system ( 1981 ) places the Alismatales in subclass Alismatidae, class Liliopsida monocotyledons and includes only three families as shown:

*: subclass Alismatidae

*: subclass Alismatidae

Alismatidae is a botanical name at the rank of subclass.

* subclass Alismatidae

* subclass Alismatidae

Synecdoche is closely related to metonymy ( the figure of speech in which a term denoting one thing is used to refer to a related thing ); indeed, synecdoche is sometimes considered a subclass of metonymy.

Today, the eliminativist view is most closely associated with the philosophers Paul and Patricia Churchland, who deny the existence of propositional attitudes ( a subclass of intentional states ), and with Daniel Dennett, who is generally considered to be an eliminativist about qualia and phenomenal aspects of consciousness.

The other groups of tetrapods considered more closely related to amniotes are put in the subclass Reptiliomorpha.

Structurally the DED domain are a subclass of protein motif known as the death fold and contains 6 alpha helices, that closely resemble the structure of the Death domain.

It is best known from the Cronquist system, of 1981, which placed this order in subclass Zingiberidae, of class Liliopsida.

The Thorne system ( 1992 ) placed the order in superorder Commelinanae in subclass Liliidae.

The Dahlgren system placed the order in superorder Bromelianae in subclass Liliidae.

The still older Cronquist system of 1981, which was not based on molecular data, placed the order in subclass Commelinidae of class Liliopsida and included the families Commelinaceae, Mayacaceae, Rapateaceae and Xyridaceae.

In the Cronquist system it is used for an order ( placed in subclass Commelinidae ) and circumscribed as ( 1981 ):

The Cronquist system, of 1981, did not recognise such an order, but placed most such plants in order Liliales in subclass Liliidae in class Liliopsida ( monocotyledons ) of division Magnoliophyta ( angiosperms ).

In the Cronquist system the name was used for an order placed in the subclass Commelinidae.

Fusion of the petals is a trait that was traditionally used to place the order in the subclass Sympetalae.

The Cronquist system ( 1981 ) placed the order in subclass Liliidae in the class Liliopsida monocotyledons of division Magnoliophyta angiosperms.

The Thorne system ( 1992 ) placed the order in superorder Lilianae in subclass Liliidae monocotyledons of class Magnoliopsida dicotyledons and used this circumscription:

The Dahlgren system placed the order in superorder Lilianae in subclass Liliidae monocotyledons of class Magnoliopsida angiosperms and used this circumscription:

By default, the method with the most specific argument classes is chosen ; then in the order in which parent classes are named in the subclass definition.

Cronquist placed this order in his subclass Caryophyllidae of three orders.

The Cronquist system, also recognised this order consisting of the same eight families, but organized the order in the subclass Zingiberidae of the class Liliopsida.

The name was used in the Cronquist system for an order placed in subclass Arecidae, circumscribed as ( 1981 ):

A well known system that did recognize such an order was the Cronquist system ( 1981 ) which placed the order in subclass Rosidae and used this circumscription:

The Cronquist system ( 1981 ) included the order in subclass Hamamelidae with the circumscription:

The Cronquist system, of 1981, recognized such order and placed it in subclass Dilleniidae.

It was used in the Cronquist system as an order within the subclass Asteridae in the class Magnoliopsida flowering plants.

Cronquist placed this order in his subclass Caryophyllidae of three orders.

In the 1981 version of the Cronquist system it was an order placed in subclass Dilleniidae with the following circumscription:

The Dahlgren system places the Alismatales in the superorder Alismatanae in the subclass Liliidae monocotyledons in the class Magnoliopsida angiosperms with the following families included:

A special subclass of context-free languages are the deterministic context-free languages which are defined as the set of languages accepted by a deterministic pushdown automaton and are identical to the set of languages accepted by a LR ( k ) parser.

An important subclass are the local search methods, that view the elements of the search space as the vertices of a graph, with edges defined by a set of heuristics applicable to the case ; and scan the space by moving from item to item along the edges, for example according to the steepest descent or best-first criterion, or in a stochastic search.

Primitive recursive functions are a defined subclass of the recursive functions.

As first defined by Eugene Small and Denis Lynn in 1981, the Nassophorea also included the peniculids and, in a separate subclass, the hypotrichs.

If a superclass instance is assigned its value from a subclass instance, member variables defined in the subclass cannot be copied, since the superclass has no place to store them.

Prototheria, on the other hand, was generally recognised as a subclass until quite recently, on the basis of an hypothesis which defined the group by two supposed synapomorphies: ( 1 ) formation of the side wall of the braincase from a bone called the anterior lamina, contrasting with the alisphenoid in therians ; and ( 2 ) a linear alignment of molar cusps, contrasting with a triangular arrangement in therians.

In Python, a metaclass is most easily defined as a subclass of.

This subclass, Orthogastropoda, which one perhaps could call the true snails, was defined most concisely as all gastropods which were not members of Patellogastropoda, the true limpets.

* B2, a subclass of security level B as defined by Trusted Computer System Evaluation Criteria ( TCSEC ) standards

In Clarke's 2004 review, the former order Ichthyornithiformes and the family Ichthyornithidae are now superseded by the subclass Ichthyornithes, which in the paper was also defined according to phylogenetic taxonomy as all descendants of the most recent common ancestor of Ichthyornis dispar and modern birds.

The classes in a provider typically implement the interfaces and subclass the classes defined in the service itself.
