Sagittaria cuneata is a North American species of flowering plant in the water plantain family known by the common name arumleaf arrowhead[2] or duck potato.

Sagittaria cuneata is an aquatic plant, growing in slow-moving and stagnant water bodies such as ponds and small streams.

The leaves are variable in shape, many of them sagittate (arrow-shaped) with two smaller, pointed lobes opposite the tip.

Each female flower has a spherical cluster of pistils which develops into a group of tiny fruits.

[13] The Ojibwe eat the corms for indigestion, and also as a food, eaten boiled fresh, dried or candied with maple sugar.
