Summary

Polypogon is a nearly cosmopolitan genus of plants in the grass family, commonly known beard grass or rabbitsfoot grass.

Description

Polypogon species vary in appearance; some are erect, while others drape over the ground in waves. Many have soft, fluffy inflorescences that look like rabbit's foot amulets.

Some are introduced species established outside their native ranges. Some of those are considered invasive species and noxious weeds, most notably Polypogon monspeliensis, the annual beard grass.
