Tape grass is a submersed plant that spreads by runners and sometimes forms tall underwater meadows. It is common in both still and fast-flowing waters. The leaves arise in clusters from their roots. They are about one inch wide and can be several feet long. The leaves have rounded tips, and definite raised veins. Single white female flowers grow to the water surface on very long stalks. Tape grass fruit is a banana-like capsule having many tiny seeds.
