Poaceae (weeds) - (grass family)

The Poaceae are a large family of monocots with more than 10,000 species, including many weeds.

The general characteristics of this family are:

  • the stems are hollow, but not on the internodes where the leaves emerge,
  • the leaves are nearly always arranged alternately, are elongated and have a smooth margin,
  • the base of a leaf (the sheath) encloses the stem,
  • at the junction of leaf blade and leaf sheath is a membrane or fringe of hairs (the ligule) which protects the inside of the sheath,
  • inflorescences are usually branched and bear spikelets each containing one or more flowers (florets).


  • Gramineae
