Sagittaria subulata, also known as the awl-leaf arrowhead or dwarf sagittaria, is a special kind of aquatic plant. This means it is a plant that grows in water. You can usually find it in shallow brackish water. Brackish water is a mix of fresh water and salty ocean water.
This plant often grows along coastlines, in marshy areas, and in estuaries. Estuaries are places where rivers meet the sea. It is naturally found in Colombia, Venezuela, and many US states along the Atlantic coast. These states include Massachusetts down to Louisiana.
Sometimes, Sagittaria subulata can be found in new places where it wasn't originally from. For example, it has been seen in Great Britain a few times. It has also been reported in the Azores and on the island of Java in Indonesia. When a plant grows in a new area on its own, it is called "naturalized." If humans bring it there, it's called "non-native."
About the Awl-Leaf Arrowhead
Sagittaria subulata is a perennial herb. This means it is a plant that lives for more than two years. It can grow up to 40 centimeters (about 16 inches) tall.
What It Looks Like
The leaves of this plant can be either fully under the water (submersed) or floating on the surface. They are usually long and thin, but can also be wider and oval-shaped. The leaves do not have any lobes or deep cuts.
The plant's flowers grow on a stalk called an inflorescence. This part of the plant floats on the water's surface.
Protecting This Plant
In some parts of the United States, Sagittaria subulata needs special protection. This is because its populations are getting smaller.
- In Connecticut, it is listed as a "special concern" species. This means scientists are watching it closely.
- In Massachusetts, it is considered "endangered." This means it is at a very high risk of disappearing.
- In Pennsylvania, it is listed as "rare." This means there are not many of these plants left.
- In Rhode Island, it is listed as "historical." This means it was once found there, but might not be anymore.
Protecting these plants helps keep our natural environments healthy.
