There are over 9,000 species of grasses. These plants have leaves with blades on the end and spiky flowers. This family includes some of the plants that are most important to people. These include cereals, grains, lawn grass, and bamboo. Rice is best known for its small seeds, which are an important food all over the world.

Annual or perennial herbs, rarely woody, often with rhizomes or stolons. Culms usually cylindric, usually hollow but solid at the nodes. Leaves: alternate, 2-ranked, simple, consisting of sheath, ligule and lamina; sheath surrounding the stem, usually open; ligule usually present at junction of sheath and lamina, membranous, a row of hairs or 0; lamina linear to filiform, rarely lanceolate or ovate. Inflorescence consisting of numerous spikelets arranged in a spike, raceme or panicle. The basic unit of the inflorescence is the spikelet, consisting of a number of florets arranged distichously along an axis (rhachilla). At the base of the spikelet are 2 (rarely 0, 1 or more than 2) empty bracts (glumes). Each floret is enclosed within an outer bract (lemma) and an inner bracteole (palea). The palea is usually membranous and 2-keeled, the lemma is usually tougher and often awned. The lemma, palea and flowering parts are together called the floret. Flowers usually bisexual, but sometimes unisexual. Perianth represented by 2(–3) minute hyaline fleshy scales (lodicules). The base of the spikelet or floret may have a horny prolongation downwards (callus). Stamens (1-)3(-6); anthers versatile. Ovary superior, 1-locular with 1 ovule often attached to the adaxial side of the loculus, to a point or line visible in fruit as the hilum. Styles (1-)2(-3), generally with plumose stigmas. Fruit 1-seeded, usually a caryopsis, rarely with seed free from the pericarp.

Elaborate stigmas capture pollen grains: grasses
 

The stigmas of grasses capture flying pollen due to their elaborate shape.

   
  "[The flowers] of grasses consist of no more than tiny clusters of dry brown or greenish scales from which the stamens protrude when the right moment comes. Their stigmas, which have to intercept flying pollen grains are particularly elaborate, often shaped like combs." (Attenborough 1995:96-98)

Leaves resist crosswise tearing: grasses
 

The leaves of grasses resist crosswise tearing due to their composite character.

   
  "Equally impressive is the composite character and consequent resistance to crack propagation of the leaves of grasses, also investigated by Vincent (1982). If a grass leaf is slit or notched it does tear more easily, but only (and fairly precisely) in proportion to its reduced cross section--there's just no sign of any significant stress concentration. Do your worst to a grass leaf--it just doesn't go along with attempts to tear it crosswise." (Vogel 2003:340)
