|discussion=<p>Polypogon is a pantropical and warm-temperate genus of about 18 species. There are eight species in the Flora region; one species, P. interruptus, is native.</p><!--
--><p>Polypogon is similar to Agrostis, and occasionally hybridizes with it. It differs from Agrostis in having spikelets that disarticulate below the glumes, often at the base of a stipe.</p>
