Casuarina glauca, commonly known as the swamp she-oak, swamp oak, grey oak, or river oak,[1] is a species of Casuarina native to the east coast of Australia. It is found from central Queensland south to southern New South Wales. It has become naturalised in the Everglades in Florida where it is considered a weed.[2]

The larvae of the she-oak moth, Pernattia pusilla, feed on C. glauca.

C. glauca is an actinorhizal plant producing root nitrogen-fixing nodules infested by Frankia. There is a regular pattern of cell layers containing flavans.[3] Although not a legume, C. glauca, produces a hemoglobin (not a leghemoglobin) in its symbiotic root nodules.[4]
