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:
“If mothers are to be successful in achieving their child-rearing goals, they must have the inner freedom to find their own value system and within that system to find what is acceptable to them and what is not. This means leaving behind the anxiety, but also the security, of simplistic good-bad formulations and deciding for themselves what they want to teach their children.”
—Elaine Heffner (20th century)
