Bermuda grass usually is 10 to 40 cm (4 to 16 inches) tall, with short, flat leaves. The spikelets are borne in four or five slender spikes at the tips of the upright stems. Extensively creeping stolons and rhizomes (aboveground and underground horizontal stems) enable Bermuda grass to establish a dense turf. It is used in warmer parts of North America as a lawn and pasture grass and for golf greens.
