Sm. }}Sagittaria isoetiformis, common name quillwort arrowhead,[1] is an aquatic plant species native to Cuba and to the southeastern United States (Florida, Alabama, Mississippi, Georgia, North Carolina and South Carolina).[2]Sagittaria isoetiformis is similar to Sagittaria tenuis and often mistaken for it, but Sagittaria isoetiformis has flattened leaves rather than leaves round in cross-section. Leaves of both species are usually submerged but sometimes emerging from the water.[3][4][5] References1. ^{{PLANTS|id=SAIS|taxon=Sagittaria isoetiformis|accessdate=26 October 2015}} 2. ^{{Cite web|url=http://apps.kew.org/wcsp/namedetail.do?name_id=287240|title=World Checklist of Selected Plant Families: Royal Botanic Gardens, Kew|website=apps.kew.org|language=en-GB|access-date=2017-01-30}} 3. ^Godfrey, R.
