Wim, Gold, CVU. Also Qld, NSW. Known in Victoria by only two collections from near Stawell, north of the Grampians, where occurring in open Eucalyptus leucoxylon woodland.
Distinctive by the dense inflorescence, the uniformly scabrous lemma and fine subapical awn. The Victorian collections are remarkably disjunct from the nearest known occurrences near Canberra from where it extends to southern Queensland.
