"Plants in the genus Sagittaria often have the common name of Arrowleaf, in
obvious reference to the shape of the leaves. Several species with lance or
ribbon shaped leaves also occur. The roots of these aquatic plants are
tubers, and have been used for centuries as a food source in the Americas
and Asia. Several species in this genus are now rare or endangered, while
others are more common and grown as ornamentals."
