|discussion=<p><i>Sorghum halepense</i> is native to the Mediterranean region. It is sometimes grown for forage in North America, but it is considered a serious weed in warmer parts of the United States. It hybridizes readily with <i>S. bicolor</i>, and derivatives of such hybrids are widespread. The annual <i>Sorghum</i> xalmum Parodi, which has wider (2-2.8 mm) sessile spikelets with more veins in the lower glumes (13-15 versus 10-13) than <i>S. halepense</i>, is one such derivative.</p>
