Stems erect, simple below the inflorescence, leafy at the base. Inflores- 
cence of the same forms as in Cyperus. Spikelets oblong or linear, com- 
pressed ; rhachilla disarticulating above the two lowest empty glumes, and 
falling away in one piece, leaving a terminal rounded boss or knob. All 
other characters as in Cyperus. 
Species about 180, found in all tropical and subtropical regions, but not extending 
into Europe. The single a cole species is endemic.
