The stems are approximate, robust, measuring 60-175 cm x 12-15 mm, spongious, triangular with concave sides and smooth. [2]
The lower leaves are reduced to spongious sheaths up to 20 cm long. The upper ones are much shorter than the stem but with small blade which is 5-10(-18) mm wide and abruptly acuminate. [2]
The inflorescence is broader than long and measures about 15 cm in diametre. There are 3-4 involucral bracts which are flat, erect to reflexed, measuring up to 30 cm x 8-15 mm and overtop the inflorescence. There are 3-6(-10) primary rays which are 3-10 cm long, spreading and unequal while the secondary rays are slender and about 2 cm long. The spikes are broadly ovoid in outline with 6-12 spicately arranged spikelets. [2]
