In all warm countries, especially near the sea, one of the most generally 
distributed and abundant species of Cyperacece. 
Sir J. D. Hooker (in Trimen FI. Ceylon 5: 20) says that this species may 
have a 3-fid style. Unfortunately the sheet from Ceylon, 800 Thwaites, contains 
Pycreus polystachyus Beauv., mixed with Gyperus Zollingeri Steud., which latter 
was dissected by Hook, f., and found with 3-fid styles.
