From Pestinfo-Wiki
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).
Synonyms
- Gramineae
