	Magnoliids are a group of angiosperm organisms that include four subgroups, Canellales, Laurales, Magnoliales and Piperales. The differentiation between the larger group magnoliids and its subgroup magnoliales is sometimes confused as the result of multiple reclassifications of these groups over their course of study.

	Magnoliids are very basic forms of angiosperms, and have characteristics that carry through to other members of angiosperms, but do have slight variations between themselves. Most magnoliid flowers have unfused carpels, surrounded by one, two or no spirals of trimerous petals. Leaves of magnoliids are generally pinnate with slight variation between species. Pollen of magnoliids are generally single pored, and have two cells present during fertilization. One cell produces the pollen tube, and the other cell, the sperm nuclei, fertilizes to form the embryo. [[File:Magnolia_Seed.png\|400px\|right\|thumb\|Seed from a particular species of magnoliid tree viewed with a Scanning Electron Microscope[1]]]Most other angiosperm plants release pollen with two sperm nuclei, but most magnoliid members release sperm with only one, which splits into two during double fertilization. Seeds formed by magnoliid members are often released before the embryos are fully developed, but the large endosperm common with members of this group assist in its germination process by providing enough nutrients to properly develop.

	Magnoliales, a subgroup of Magnoliids, have widespread economic and agricultural uses. Timber of members of this family, such as lancewood found in South America and the West Indes, has a yellow wood of fine texture with very fine grain suitable for carving and miscellaneous shape-dependant uses. The fine grains of these trees may be ground up into a powder and used for a yellow dye. Several genera of these species have very flexible, elastic qualities useful for wheels, masts of ships and some house beams. Custard apple, sweetsop, pawpaw and a few other species of trees are grown for their fruits. The Myristica Fragrans plant is the source of both nutmeg and mace.

[6] Avocados are a fruiting tree of the laurel order and family whose use in commercial cooking is massively widespread. Eaten as a whole, chopped, ground or mashed in or on a massive variety of other foods. Mostly native to warm, tropical climates, they are cultivated in large numbers in Mexico and California. [7] Kava, a pepper like member of the piper order, family and genus, is cultivated and consumed for its psychedelic effects. The roots of this plant are grated, or chewed, mixed with water and then strained. The resulting liquid is drank to produce a relaxed and euphoric experience. [8]

The members of this group vary greatly morphologically and geographically.
