Queensland: Springsure, coll. Wuth; Peak Downs, coll. Burkitt. 
A distinct species, allied with P. flavidum, which has however a 
different panicle with two dense rows of sessile spikelets, usually very 
oblique and smaller, with thinner and less-nerved glumes.

distantibus suberectis ca. 2 cm longis omnibus usque ad paniculae apicem 
similibus, rachide ramulorum flexuosa compressa dilatata ca. 5/, mm 
lata apice nuda, spiculis subsessilibus distichis densis parvis vix 3 mm
