Sagittaria subulata, the awl-leaf arrowhead,[2] narrow-leaved arrowhead[3] or dwarf sagittaria, is an aquatic plant species that grows primarily in shallow brackish water along the seacoast, in marshes, estuaries, etc. It is native to the Republic of Colombia, the District of Columbia, Venezuela, and every US state along the coast from Massachusetts to Louisiana.[4][5] It has also been reported as naturalized in Great Britain on just three occasions; only one of these is recent and it appears to have become extinct by 2010. It is also recorded as a non-native on the Azores, and on the Island of Java in Indonesia.[6]
