Annual to woody perennial herb; roots generally fibrous. Stem: generally round, hollow; nodes swollen, solid. Leaf: alternate, 2-ranked, generally linear, parallel-veined; sheath generally open; ligule membranous or hairy, at blade base. Inflorescence: various (of generally many spikelets). Spikelet: glumes generally 2; florets (lemma, palea, flower) 1–many; lemma generally membranous, sometimes glume-like; palea generally ± transparent, ± enclosed by lemma. Flower: generally bisexual, minute; perianth vestigial; stamens generally 3; stigmas generally 2, generally plumose. Fruit: grain (rarely achene-like).
650–900 genera; ± 10550 species: worldwide; greatest economic importance of any family (wheat, rice, maize, millet, sorghum, sugar cane, forage crops, ornamental, weeds; thatching, weaving, building materials). [Barkworth et al. 2003 FNANM:25; Barkworth et al. 2007 FNANM:24] Generally wind-pollinated.

Key to Poaceae
Perennial herb, generally cespitose, rhizomed or not, corms present or 0. Stem: generally erect. Leaf: ± basal; sheath closed to near top, glabrous to short-hairy; ligule thin, membranous, tip obtuse to truncate, generally jagged; blade flat, veins inconspicuous. Inflorescence: raceme- or panicle-like, generally appressed to main axis. Spikelet: glumes papery, translucent, back rounded, tip rounded, lower glume 3–5-veined, upper 1–3-veined; axis generally breaking above glumes; lower florets bisexual, 1–7, uppermost florets sterile, ± densely clustered at axis tip; lemma ± like glumes, prominently 5–7-veined, veins not converging, base occasionally red; palea < lemma.Key to Melica
