This species might well be regarded as an extreme form of E. acicularis.
However, its slender compact habit, sparse inflorescence, and smooth floret
indicate a closer relationship to E. unispiceus. E. paucispiceus
differs from E. unispiceus in having fewer culm nodes, usually more
spikes, and longer leaf blades, callus and awn on the fertile floret.

SE Qld, from the coast to c. 600 km inland. Occurs in
brigalow (Acacia harpophylla) country, in heavy soils, or in Eucalyptus
forest on sand and sandstone slopes and hilltops.
