Cronquist system

From Free net encyclopedia

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; 2n edition, 1988).

Cronquist's system places flowering plants into two broad classes, monocotyledons and dicotyledons. Related orders are placed 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):
