Its species tend to occur in moist soils, often in areas subject to winter flooding. The three species found in the Flora region are very plastic in the lengths of their culms and leaves, e.g., the culms of C. schoenoides vary from 2 cm in dry sites to 75 cm under optimal conditions.</p> |tables= |references={{Treatment/Reference |id=hammel1979a |text=Hammel, B.E. and J.R.
