Distinguished by the sparsely hairy lemmas, with usually deep subulate lobes;
usually glabrous, relatively long paleas with prominently winged keels;
strongly 3-nerved glumes; paniculate inflorescence; indumentum of long,
straight, stiff hairs on orifice, which extend along margins of blades in
and islands of NW W.A. (N of 24°S) and areas of N.T. adjacent to East Gardner
and Hall Districts of the Kimberley Region. Commonly in shallow and skeletal,
rocky soils and gullies on hills, ridges, plateaux, mountains, ranges, gorges
and outcrops of limestone; also in association with granite, sandstone,
quartzite, shale, schist, basalt, chert and laterite; in alluvial, red stony
clay loam, coarse sandy and gravelly soils on plains and gentle slopes, stony
downs, sandplains, valley floors, grass steppes, creek beds, floodouts and
banks, and drainage lines; flowers all seasons.
