Here is an example of Carex intumescens in the family of cyperaceae:

This picture was taken in April 2007 at Mule Jail, very close to the Pearl River.  A North American native, this plant is found from Newfoundland to Florida and west to Wyoming.  It happens to be threatened in Illinois and those folks call it swollen sedge.  C. intumescens has some notable relatives in the family cyperaceae, according to Wikipedia, both water chestnuts and papyrus of the paper making kind call this little plant cousin.

This is Eleocharis obtusa in the family cyperaceae:

This particular plant was photographed at LeFleur's Bluff state park on May 11, 2010.  This plant is a native of the Contiguous 48 States, Canada and Hawaii.  It isn't a large plant, rather, it has numerous stalks each topped with the flower picture above.  The stalks radiate from a common base that, for this specimen, was obscured by the shallow water/mud it was growing in.
