Columbia Encyclopedia entry: Magnoliophyta
Magnoliophytamăg′nōlēŏf'ətə, division of the plant kingdom consisting of those organisms commonly called the flowering plants, or angiosperms. The angiosperms have leaves, stems, and roots, and vascular, or conducting, tissue (xylem and phloem). The ovules, which develop into seeds, are enclosed within an ovary, hence the term angiosperm, meaning enclosed seed. The flowering plants are the source of all agricultural crops, cereal grains and grasses, garden and roadside weeds, familiar broad-leaved shrubs and trees, and most ornamentals.Class Magnoliopsida (Dicotyledons)

Plants of this class usually have two seed leaves, or cotyledons, and cambium tissue in the stems (see meristem). Much the larger of the two classes of flowering plants, dicots are divided into many families, among which several of the more conspicuous and easily recognized are the willow, buttercup, pink, mustard, saxifrage, rose, pea, heather (see heath), gentian, bluebell, and aster families.

Class Liliopsida (Monocotyledons)

Plants of this class generally have only one seed leaf, or cotyledon, and generally lack cambium tissue. The most common families are the grass, palm, arum, sedge, lily, and orchid families.

From Wikipedia, the free encyclopedia
The flowering plants (redirected from Magnoliophyta) or angiosperms are the most diverse group of land plants. The flowering plants and the gymnosperms are the only extant groups of seed plants. The flowering plants are distinguished from other seed plants by a series of apomorphies, or derived characteristics. The ancestors of flowering plants diverged from gymnosperms around 245–202 million years ago, and the first flowering plants known to exist are from 140 million years ago. They became widespread around 100 million years ago, but replaced conifers as the dominant trees only around 60-70 million years ago.
