This genus is Cyperi Sect. Juncellus of Kunth, and differs from Gyperus by 

 having a 2-fid style, and more or less compressed, not equilaterally trigonous nut. 

 Several of the species have been considered by Boeckeler and others as forma with 

 2-branohed styles of corresponding species of Gyperus.
