Cyperus victoriensis, also known as channel nut grass is a sedge of the family Cyperaceae that is native to all the states and territories of mainland Australia.[1] [2]
The rhizomatous perennial herb to grass-like sedge typically grows to a height of 0.6to. It has slender rhizomes that form ovoid to ellipsoid shaped woody tubers that are 5to in diameter. The mostly terete culms are smooth and trigonous with a length of 30to and a diameter of 3mm. The leaves are not septate-nodulose and usually half the length of the culm with a width of 2to.
The simple inflorescence has three to eight primary branches with a length of about 5cm (02inches) that is often bent under the weight of the spikelets. The spikes have an ovoid shape and a length of around 41NaN1 and a diameter of around 31NaN1. The spikelets are flattened with 3 to 15 on each spike containing around 40 flowers. Later a trigonous, narrowly obovoid gery-brown to black nut will form with a length of 1.5to and a diameter of 0.73NaN3.
The species was first formally described by the botanist Charles Baron Clarke in 1908 in the Bulletin of Miscellaneous Information, Royal Gardens, Kew.[2]
It is endemic to mainland Australia and is found in all states.[3] In Western Australia and is found along streams and creeks in the Kimberley region where it grows in sandy-clay soils.In New South Wales it is widespread through most non-coastal areas and is known on floodplains and the banks of inland watercourses mostly on clayey soils.[3] It is found in north western Victoria from the mallee through to the Riverina.[4]
