- Grass
- Plants of the family Poaceae (Gramineae). Grasses are characterized by rounded, hollow or pithy jointed stems (culms), and narrow sheathing leaves with parallel veins. The leaves alternate on two sides of the stem. The junction of the blade and sheath often bears an erect fringe of hairs (ligule) and sometimes also earlike projections (auricles). Flowers are borne in reduced spikes (spikelets). See drawing of plant group characteristics.
- Grazing Value
- The worth of a plant to livestock, as determined by its palatability, nutritive quality, volume of forage produced, longevity, and area of primary distribution. Good grazing value applies to a plant that is in top volume production, is highly palatable (not necessarily in all seasons), and nutritious. Fair grazing value means that the plant is less desirable in palatability, quality, or volume of production. Poor grazing value indicates that the plant rates the lowest in one or more basic requirements in most areas where found. An abundance of such plants indicates a range in poor condition.
