A. strigosa resembles A. capillifolia in that it has distinctly
scabrous lemmas as opposed to tuberculate spiny lemmas found in A. nitidula,
A. arida and A. platychaeta. It differs from A. capillifolia
by having flat to conduplicate leaf blades and longer lemmas.
Mainly from southern
part of the N.T. to northern South Australia with scattered distribution in all
mainland states except Victoria. Rocky creek beds and associated sandy or loamy
alluvial soils. Flowering and fruiting January to November.
