Rush fuirena is an emersed plant commonly found growing in fresh and brackish marshes and lake and pond margins throughout Florida. It blooms from spring to fall. Five species of Fuirena occur in Florida (Wunderlin, 2003). Rush fuirena is located in AL, FL, GA, IL, LA, MS, NC, and TX (Kartesz, 1999).
Rush fuirena stems grow to about two feet tall. The stems are jointed. There are sheaths at the joints. This plant has no leaf blades, but does have leaf sheaths encircling the stem. The inflorescence of rush fuirena is at the top of the stem and consists of one to three rather large 1/2 inch spikelets. The spikelets are brown, blunt ovoids.
