The Cronquist system is a taxonomic classification system of flowering plants. It was developed by Arthur Cronquist in his texts An Integrated System of Classification of Flowering Plants (1981) and The Evolution and Classification of Flowering Plants (1968; 2nd edition, 1988).
Cronquist's system places flowering plants into two broad classes, Magnoliopsida (dicotyledons) and Liliopsida (monocotyledons). Within these classes, related orders are grouped into subclasses.
The scheme is still widely used, in either the original form or in adapted versions, but many botanists are adopting the Angiosperm Phylogeny Group classification for the orders and families of flowering plants: APG III.
The system as laid out in An Integrated System of Classification of Flowering Plants (1981) counts 321 families and 64 orders in class Magnoliopsida with 19 orders and 65 families in class Liliopsida:

Famous quotes containing the word system:
“UG [universal grammar] may be regarded as a characterization of the genetically determined language faculty. One may think of this faculty as a ‘language acquisition device,’ an innate component of the human mind that yields a particular language through interaction with present experience, a device that converts experience into a system of knowledge attained: knowledge of one or another language.”
—Noam Chomsky (b. 1928)
