Grass

Grass is the common name given a whole variety of plants, that technically, should be restricted to monocotyledonous plants in the family Poaceae. These true grasses include most of the plants grown as cereals, for pasture, and for lawns. Grasslands, or prairies, are habitats that are marked by open expanses of grasses.

Grasses also include some more specialised crops such as the herb, lemongrass, as well as many ornamental plants, and some weeds. They also include plants often not considered to be grasses, such as bamboos.
