Distinguished by villous leaves, high colour, relatively long ligule,
inflorescence of usually 2 stiff spikes, firm dissimilar glumes, subapically
bearded floret, acute callus, and scarcely compressed grain. The spikes
resemble those of B. convergens, but this species has glumes with acute
winged keels, a strongly compressed grain, and usually glabrous foliage. Also,
the nerves of the lemma and keels of the palea, though ciliate or pubescent,
lack a subapical tuft.

occurs in the arid and low rainfall areas of inland Australia from Alice
Springs E across the L. Eyre basin between 20°S and 31°S, and within 300 km of
the Qld coast around the Tropic of Capricorn; Usually on sandy, gravelly or
stony slopes or plains, including gibber plains.
