The swollen tubers characteristic of Cyperus rotundus are often referred to as "nuts" and give rise to the name Nut grass. This name is also applied at times to other species of Cyperus, similar in appearance, but not producing the swollen tubers. C. rotundus is also called Java grass. Both are misnomers as the plant is, in fact, not a grass but a sedge and has none of the desirable features of the true grasses.
