It blooms between July and March producing brown flowers.[1] It normally has a short thick rhizome with smooth, trigonous and terete culms. The leaves are reduced to sheaths, except for juvenile plants.[2] C. gymnocaulos is usually smaller and less robust than C. vaginatus.[2]TaxonomyThe species was first formally described by the botanist Ernst Gottlieb von Steudel in 1854 as part of the work Synopsis Plantarum Glumacearum. Known synonyms include; Cyperus cruciformis and Cyperus vaginatus var. densiflorus. The name is commonly misapplied to Cyperus textilis.[3] DistributionIt is found in swamps and along creeks and rivers and other damp areas in all the states of mainland Australia as well as the Northern Territory.[2] In Western Australia it is found in the Mid West, Wheatbelt, South West and Goldfields-Esperance regions where it grows in sandy-clay soils.[1] See also
