Distinguishing features include inflated tightly imbricate florets falling
entire with rachilla internode; thickened rachilla; orbicular, pouched paleas
with much-reduced keels and flaps; biconvex caryopsis and spiciform panicle.
The reduced keels and their auricle-like flaps are unique features in
Australian species and possibly within the genus.
