Heteropogon is a small genus of annual and perennial grasses known generally as tangleheads. They are erect tussock grasses found in tropical regions worldwide, and some species grow in warmer temperate areas as well. The inflorescences hold paired spikelets. Lower pairs are equal in size (homogamous units), and upper pairs include one awned bisexual spikelet and one awnless sterile spikelet (heterogamous units). The name of the genus is derived from the Greek words έτερος (éteros), meaning "different," and πογον (pogon), meaning "beard."[2]
