Cyperus gymnocaulos, commonly known as spiny flatsedge, is a sedge of the family Cyperaceae that is native to Australia.[1]

Description[]

The rhizomatous perennial grass-like sedge typically grows to a height of 0.35 to 1 metre (1.1 to 3.3 ft) and has a tufted habit. 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]

Taxonomy[]

The 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]

Distribution[]

It 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]
