This family is also known as Poaceae family.
The family consists of plants that are generally cultivated as crop plants for food.
They are terrestrial, annual herbs.
They are typically monocotyledonous.
Roots: They have fibrous or adventitious root system. Some may have stilt roots (e.g. maize).
Stem:
Stem is erect and herbaceous with distinct nodes and internodes.
May be branched (branching from the base, i.e. tillering) or unbranched.
It is cylindrical, ribbed, hollow and joined at the nodes.
Greenish yellow in color and is liable to fall easily.
Leaves:
Leaves are simple. They may be cauline, alternate, green and exstipulate.
Entire margin with parallel venation and acute apex.
Leaf base has a sheath and membranous ligule is present at the junction of leaf sheath and leaf blade.
Inflorescence:
Terminal panicle, spike or spikelets
Spikelet may be short stalked, consisting of a pair of glumes (e.g. barley).
Male spikelets in terminal panicled racemes called tassel and female in axillary spikes called cob or ear (e.g. maize).
Flower:
Bracteate, sessile, zygomorphic and may be bisexual (e.g. rice) or unisexual (e.g. maize).
It is incomplete and hypogynous. Flower lies in between superior and inferior palea.
Perianth:
It is represented by two broad, thick and fleshy lodicules.
Androecium:
Stamens are either 3 (e.g barley, maize, wheat) or 6 (e.g. rice) in number and are polyandrous.
Filament is long, anthers are bilobed and dorsifixed when young and versatile when mature.
Gynoecium:
Monocarpellary and the ovary is superior.
It is unilocular with a single basal ovule.
Style may be present (e.g rice) or absent (e.g. wheat, barley).
Stigma 2 and are feathery.
Fruit: Caryopsis
