Spikelets. Spikelets
pedicelled. Fertile spikelets 1 or more flowered, with 1 fertile floret,

Notes. The
leafy tussocks are moderately palatable when young, but the rather coarse
mature foliage and the numerous long flowering culms are not normally grazed.
In general the species is considered less valuable than A. pectinata..

Distributed across
most of the N.T. and Qld S of 15°S, excepting the Channel country of Qld,
extending into north- central N.S.W. with a few occurrences recorded from the
Pilbara and Kimberley regions of W.A. It often occurs with A. squarrosa. In
central Australia, sometimes on alluvial soils as well as the usual cracking
clays, and is associated with A. pectinata, Eragrostis setifolia
(Neverfail) and to a lesser extent with Acacia cambagei (Gidgee).
Elsewhere usually found on treeless downa often subject to seasonal or
occasional inundation, with other Astrebla species, Iseilema spp.
(Flinders Grass) and Dichanthium spp. (Bluegrass): flowers after rain.
