|synonyms_ref = [1] }} Sagittaria australis, the Appalachian arrowhead or longbeak arrowhead, is a plant species native to much of the eastern part of the United States, from Louisiana to Iowa to New York State to Florida, mostly between New Jersey and Mississippi with scattered locations elsewhere in the range. It is an emergent aquatic, growing in swamps and along the edges of lakes and ponds.[2][3] It is sometimes sold as an ornamental to be cultivated in aquaria or garden ponds.[4][5][6] Sagittaria australis is a perennial herb up to 130 cm (50 inches) tall. It is unusual in genus in having a 5-winged petiole. Flowers are up to 3 cm (1.2 inches) in diameter, white, producing an achene with a recurved beak.[2][7][8]References1. ^Tropicos 2. ^1 {{Cite web|url=http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=222000328|title=Sagittaria australis in Flora of North America @ efloras.org|website=www.efloras.org|access-date=2017-01-30}} 3. ^{{Cite web|url=http://apps.kew.org/wcsp/namedetail.do?name_id=287230|title=World Checklist of Selected Plant Families: Royal Botanic Gardens, Kew|website=apps.kew.org|language=en-GB|access-date=2017-01-30}} 4. ^{{Cite web|url=http://www.seerosensorten.de/nc/wasserpflanzen-shop/wasserpflanzen/detailseite/seerose/sagittaria-australis-benni.html|title=Sagittaria australis 'Benni' {{!}} Wasserpflanzen {{!}} Wasserpflanzen Shop {{!}} Seerosensorten|last=#IndexMetaAuthor#|website=www.seerosensorten.de|language=de|access-date=2017-01-30}} 5. ^{{Cite web|url=http://www.jardindupicvert.com/4daction/w_partner/sagittaire_benni_silk_stocking_sagittaria_australis.13771|title=Sagittaria australis Benni Silk Stocking - Sagittaire - Pépinière, plantes, jardinerie, vente en ligne|website=www.jardindupicvert.com|access-date=2017-01-30}} 6. ^{{Cite news|url=http://www.waterplantsitaly.com/negozio/sagittaria-australis-benni/|title=Sagittaria australis 'Benni' - Piante acquatiche - Water Plants Italy|newspaper=Piante acquatiche - Water Plants Italy|language=it-IT|access-date=2017-01-30}} 7. ^[https://www.biodiversitylibrary.org/page/376932#page/55/mode/1up Small, John Kunkel.
