Gold, MuF, MuM, MSB, NIS, RobP, VRiv, VVP, Wim. All mainland states. Uncommon in Victoria, chiefly northern (rare near Melbourne at e.g. Derrimut, Eynesbury, Rockbank), occurring in seasonally wet situations such as floodways, usually on clayey soil.

The culms of this species have a unique glistening, reticulate cell-pattern (visible with a hand-lens) between the longitudinal ridges.
