|discussion=<p><i>Imperata cylindrica</i> is the most variable species in the genus. Several varieties have been recognized but, although there are statistically significant differences between plants from different regions, identification to variety without knowledge of a plant's geographic origin is risky. All North American plants examined have had 2n = 20.</p><!--
--><p><i>Imperata cylindrica</i> is one of the world's 10 worst weeds, and is listed as a noxious weed by the U.S. Department of Agriculture. It was introduced to Alabama by 1912, and has spread considerably through the southeastern United States since then. The cultivar 'Red Baron' is diminutive and non-weedy, but individual shoots may revert to the aggressive form. Such reversion is particularly common in plants grown from tissue culture.</p>
