Plants rhizomatous, loosely tufted, fairly robust perennials with leaves 4-5 mm wide that terminate in narrow prolonged downward-curling apices; occurring with grasses and suffrutices amongst basalt and dolerite rocks. Before inflorescences begin to break up in age, are conspicuous by pale golden brown male spikelets, approximately twice length of green, strongly-veined utricles. Acuminate male glumes, and persistent pyramidal style base of elliptic, trigonous achene are other useful diagnostic features.
