Lower pairs are equal in size (homogamous units), and upper pairs include one awned bisexual spikelet and one awnless sterile spikelet (heterogamous units).

Species include:
*"Heteropogon asiaticus"
*"Heteropogon contortus"
*"Heteropogon fischerianus"
*"Heteropogon melanocarpus"
*"Heteropogon patruelis"
