Sagittaria

Sagittaria is a genus of about 30 species of aquatic plants whose members are referred to by the Native American word wapato (/ˈwɒpət/) and a variety of other common names, including arrowhead, duck potato, swamp potato, tule potato, and katniss. Most are native to South, Central, and North America, but there are also some from Europe, Africa, and Asia.

Sagittaria plant stock (the perennial rhizome) is a horizontal creeper (stoloniferous). The leaf grows up to .3–.9 metres (1–3 ft) tall, with a shape resembling an arrowhead. Between July and September, a single stalk bears groups of three white flowers with three petals each. It is obliquely obovate, the margins winged, with an apical or ventral beak; in other words, they are a small, dry, one-seeded fruit that do not open to release the seed, set on a slant, narrower at the base, with winged edges, and having a "beaked" aperture (one side longer than the other) for sprouting, set above or below the fruit body.[clarification needed]

As of December 2023 accepted species include:

The genus comes from the Latin word sagittārius, meaning 'pertaining to arrows', owing to the leaf shape of many species.

Many species have edible roots, prized for millennia as a reliable source of starch and carbohydrates, even during the winter. Some are edible raw, though are less bitter when cooked. They can be harvested by hand or by treading the mud in late fall or early spring, causing light root tubers to float to the surface. The plants are easy to propagate by replanting the roots.

Native American peoples such as the Algonquian, Omaha, Pawnee, and Winnebago use the tubers for food, prepared by boiling or roasting. They were also planted and eaten in China.

Other names are Pshitola (Dakota), Si" (Omaha-Ponca), Si-poro (Winnebago) and Kirit (Pawnee), 'cricket' (from the likeness of the tuber to the form of a cricket); known also as kits-hat, 'standing in water', the tuber being termed kirit.

Sagittaria is mentioned in the Omaha myths "Ishtinike and the Four Creators" and "How the Big Turtle Went to War".
