Vallisneria is a genus of aquatic plant, commonly called eelgrass or tape grass. The genus has 6-10 species that are widely distributed, but do not grow in cold regions.

Vallisneria is a submersed plant that spreads by runners and sometimes forms tall underwater meadows. Leaves arise in clusters from their roots. 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.
