Cronquist system

A system of plant taxonomy, the Cronquist system is a scheme for the classification of flowering plants (or angiosperms). This system was developed by Arthur Cronquist (1919-1992) 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 II.

The system as laid out in An Integrated System of Classification of Flowering Plants (1981) counts 321 families and 64 orders:
