Magnoliopsida

(Class)

Overview

[ Back to top ]

A phylum within the plant kingdom comprising plants with a vascular system that bear flowers during at least some stage of their life cycle. The phylum is further subdivided into dicotyledons and monocotyledons. The Magnoliopsida is the largest phylum of land plants, represented by over 250 000 species world-wide. Syn. Angiospermophyta.
