Oreobolus pumilio

Oreobolus pumilio, commonly known as alpine tuftrush or Ibrang`rank, is a small mat forming herb which is distributed throughout the Australasian region. It is a relative of the sedge. It is often found in cushion plant communities, in alpine environments, where it is a dominant species. As a cushion plant, it is an ecological engineer and enables other species to grow in the alpine herblands to which it is native to.
