Angiosperms were formerly called Magnoliophyta (/ m æ ɡ ˌ n oʊ l i ˈ ɒ f ə t ə,-ə ˈ f aɪ t ə /). Angiosperms are distinguished from the other seed-producing plants, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds.

Angiosperms have a number of derivedcharacters, which evolved as they split off from the gymnosperms. 1. Flowers Flowers, the reproductive organs of flowering plants, are the most remarkable feature distinguishing them from other seed plants. Flowers, with their colour and their nectar, attract pollinators, which are mostly insects and birds. 95% o...
Molecular evidence indicates that the ancestors of angiosperms diverged from the gymnosperms during the late Devonian, about 365 million years ago. They did not appear in the fossil record until the Mesozoic, almost two hundred million years later. A whole genome duplication (doubling) at 160 million years ago (mya) may have started the ancestral l...

Contents. Magnoliids. Magnoliids, Magnoliidae or Magnolianae are a clade of flowering plants. With more than 10,000 species, including magnolias, nutmeg, bay laurel, cinnamon, avocado, black pepper, tulip tree and many others, it is the third-largest group of angiosperms after the eudicots and monocots.

Magnoliopsida is a valid botanical name for a class of flowering plants. [1] . By definition the class will include the family Magnoliaceae, but its circumscription can otherwise vary, being more inclusive or less inclusive depending upon the classification system being discussed. Magnolia flowers. Classification. Cronquist and Takhtajan systems.

The Magnoliaceae ( / mæɡˌnoʊliˈeɪsii /) are a flowering plant family, the magnolia family, in the order Magnoliales. It consists of two genera: Magnolia and Liriodendron (tulip trees). Unlike most angiosperms, whose flower parts are in whorls (rings), the Magnoliaceae have their stamens and pistils in spirals on a conical receptacle. [3] .
This largest radiation of land plants dates back only to the early Cretaceous in the fossil record and has become the dominant plant group in most biomes because of specialized vegetative and reproductive features. The phylum is traditionally divided into two classes, the dicots and monocots; however, this division is now being challenged.
