Asian and African specimens have an acute to acuminate spikelet apex, spikelet
length mostly below 3.9 mm and spikelets not arranged orderly on the primary
branches. Many Australian specimens previously identified as E. procera
possess neatly arranged secund spikelets with an aristate apex. It seems that E.
procera has been misinterpreted in Australia and these aristate specimens
belong to another species, probably E. decumbens. Eriochloa procera
is native to Australia, but is not as widely distributed as previously
In tropical and
subtropical rain forests, tropical and subtropical wet sclerophyll forests,
Brigalow forests, tropical and subtropical sub-humid woodlands, temperate
sub-humid woodlands, semi-arid shrub woodlands, and coastal grasslands. Flowers
sporadically throughout the year.
