Sagittaria subulata, the awl-leaf arrowhead,[2] narrow-leaved arrowhead[3] or dwarf sagittaria, is an aquatic plant species.
Description
[edit]It is a perennial herb up to 40 centimetres (16 inches) tall. The leaves are submersed or floating, narrowly linear to ovate, not lobed. The inflorescence floats on the surface of the water.[4]
Distribution and habitat
[edit]It is native to the Colombia, 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] It grows primarily in shallow brackish water along the seacoast, in marshes, estuaries, etc.
Conservation
[edit]It is listed as special concern in Connecticut,[7] as endangered in Massachusetts, as rare in Pennsylvania, and as historical in Rhode Island.[8]
