Usually very large, but as in many species of Gyperacece, small examples occur. 
The "type" example of Presl, is very young, the heads being quite small; hence his 
inappropriate specific name. 
Southeastern Asia; common. Also in Bourbon, Mauritius.

A strong plant, leaves almost spongy with transverse lines; umbel
