Panicum queenslandicum Domin APNI* 
Description: Densely caespitose, perennial to 0.8 m high, the innovations often extravaginal.
Leaves with sheath mostly glabrous; ligule a dense row of cilia c. 1 mm long; blade to 3.5 mm wide.
Panicle at length exserted, compound, stiffly and widely spreading, to 28 cm long and about as broad with rather few spikelets produced in twos and threes at the apices of the rigid branches; lower branches whorled, to 25 cm long. Spikelets 3–7 mm long, pale or purplish, glabrous. Lower glume 75–95% the length of the spikelet, usually 5-nerved, minutely scabrid on the midnerve near the tip; upper the shape and size of the spikelet, 5–7-nerved. Lower floret sterile; lemma similar to the upper glume 5–7-nerved; palea hyaline, or absent. Upper lemma crustaceous, smooth, shining, obscurely nerved, obscurely very finely striolate.
