Heteropogon is a genus of annual and perennial plants in the grass family known generally as tangleheads, widespread primarily in tropical and subtropical regions. Tangleheads are erect tussock grasses with 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 (héteros), meaning "different," and πώγων (pôgôn), meaning "beard." see Agenium Dichanthium Diectomis Diheteropogon Elymandra Hyparrhenia Parahyparrhenia Trachypogon • Heteropogon androphilus - Elymandra androphila • Heteropogon arrhenobasis - Hyparrhenia arrhenobasis • Heteropogon bellariensis - Parahyparrhenia bellariensis • Heteropogon buchneri - Diheteropogon filifolius • Heteropogon concinnus - Dichanthium caricosum • Heteropogon filifolius - Diheteropogon filifolius • Heteropogon grandiflorus - Diheteropogon filifolius • Heteropogon hagerupii - Diheteropogon hagerupii • Heteropogon hirtus - Hyparrhenia hirta • Heteropogon hochstetteri - Diectomis fastigiata • Heteropogon leptocladus - Agenium leptocladum • Heteropogon megapotamicus - Trachypogon spicatus • Heteropogon oliganthus - Dichanthium oliganthum • Heteropogon pubescens - Hyparrhenia hirta • Heteropogon secundus - Trachypogon spicatus • Heteropogon stipoides - Trachypogon spicatus • Heteropogon tenellus - Dichanthium caricosum • Heteropogon tenuiculus - Dichanthium sericeum • Heteropogon truncatus - Trachypogon spicatus • Heteropogon villosus - Agenium villosum
