Distinguished by the slender spikes, relatively small spikelets, an acute
wingless keel on the glumes, minute obtuse callus, rather distant keels on the
palea, and a grain which is not compressed. The indumentum between the nerves
on the lemma is distinctive, although sometimes also occurring less markedly in
from the W.A. Kimberley region across the northern half of the N.T. to
Normanton in Qld, and in the eastern half of Qld in the drier inland regions;
In swampy areas and flood plains both inland and near the coast, sometimes in
water, usually on heavy soils, with other grasses, occasionally in woodland;
flowers Jan.-Mar. in the Kimberley.
