Sagittaria engelmanniana (Engelmann's arrowhead[3] or acid-water arrowhead) is an aquatic plant species native to eastern North America. It has been reported from every state bordering on the Gulf of Mexico or on the Atlantic Ocean from Mississippi to Massachusetts, plus Vermont and Ontario.[4][5][6]

Sagittaria engelmanniana occurs in wetlands, predominantly those with acidic water such as Sphagnum bogs. It is a perennial herb up to 70 cm tall. Leaves are sagittate (arrow-shaped) with 3 very narrow lobes.[1][5]
