Sagittaria cuneata


Sagittaria cuneata is a species of flowering plant in the water plantain family known by the common name arumleaf arrowhead or duck potato. Like some other Sagittaria species, it may be called wapato. It is native to much of North America, including most of Canada as well as the western and northeastern United States.
Sagittaria cuneata is an aquatic plant, growing in slow-moving and stagnant water bodies such as ponds and small streams. It is quite variable in appearance, and submerged parts of the plant look different from those growing above the surface or on land. In general it is a perennial herb growing from a white or blue-tinged tuber. The leaves are variable in shape, many of them sagittate with two smaller, pointed lobes opposite the tip. The leaf blades are borne on very long petioles. The plant is monoecious, with individuals bearing both male and female flowers. The inflorescence which rises above the surface of the water is a raceme made up of several whorls of flowers, the lowest node bearing female flowers and upper nodes bearing male flowers. The flower is up to 2.5 centimeters wide with white petals. The male flowers have rings of yellow stamens at the centers. Each female flower has a spherical cluster of pistils which develops into a group of tiny fruits.
