Interesting features of this species include the highly branched culm, reflexed
leaves and oblique orientation of the spikelets. Spikelet length distinguishes
it from the other Australian species.
In tropical and
subtropical wet sclerophyll forests, Brigalow forests, tropical and subtropical
sub-humid woodlands, and semi-arid shrub woodlands. Widespread in tropical Australia.
Flowers throughout the year, mostly Dec.-June.
