		The Poaceae is the world's fifth largest plant family, exceeded in numbers of species only by the Asteraceae, Orchid- aceae, Fabaceae and Rubiaceae. It was formerly known as the Gramineae and is known to everyone as the grass family. It contains about 600 genera and between nine and ten thousand species. Grass- lands comprise 20% of the vegetation cover of the earth, and the Poaceae with food grains, forage grasses and bamboos used in construction is without question the most important of all plant families to human economies. Just three cereal grains (rice, wheat, and maize or corn) provide more than half of all calories eaten by humans, and 70% of all crops are grasses. Barley, oats, rye, millet and sugar cane are other major agricultural crops. Grasses are quite different from other plants, with very distinctive features that require learning a whole new set of botanical terms.
