The erect perennial sedge typically grows to a height of 0.2to and has a tufted habit. It blooms between January and July and produces green-yellow-brown flowers.
It is found in seasonally dry tropical areas in Queensland, the Northern Territory and Western Australia.[1] In Western Australia it is found on rocky hillsides, cliffs, among boulders, in rock crevices and in creek beds in the Kimberley region where it grows in sandy soils over sandstone.
