A small, grass-like plant, Wolf’s spike-rush (Eleocharis wolfii) can often be found growing in small tufts or clumps. The stems of Wolf’s spike-rush are blue-green, upright and usually very flat or even inrolled (2) (3) (4). The sides of the stems can be either smooth or marked with a number of ridges (2), and the leaf sheath at the base may be dark red, brown or straw-coloured (2) (3) (4).
Wolf’s spike-rush has small rhizomes that are light brown to white in colour (2). The flowers of this species are arranged spirally in an oval to lance-shaped group, or ‘spikelet’, at the end of the stem (2) (3). The flowers are covered in scales which can be dark red, orange-brown, straw coloured, or colourless, while the central vein of the scale can vary from orange-brown or straw-coloured to colourless (2).
The fruit of Wolf’s spike-rush is pear-shaped and is pale yellow, brown, grey or nearly white (2) (3). A small growth on the fruit, known as a tubercle, is pyramidal and brown (2).
