Amphibromus

Amphibromus is a genus of grasses in the family Poaceae. Most are known as swamp wallaby grass. Most are endemic to Australia. One can also be found in New Zealand and there are two species in South America.

These are annual or perennial grasses. Some can have cleistogamous inflorescences sheathed on their stems. The open inflorescences may be spreading or spikelike. These may have some cleistogamous spikelets in them, as well.

Most species occur in moist to wet habitat types. Some tolerate periodic flooding well, even flowering in response to it.
