Two species are established in the Flora region. In using the key and descriptions, the lowest floret in a spikelet should be examined. Succeeding florets tend to have shorter, less acute or acuminate lobes, and a shallower sinus.</p> |tables= |references={{Treatment/Reference |id=conert1974a |text=Conert, H.J. and A.M. Turpe. 1974.
