Eriocaulon parkeri

Eriocaulon parkeri is a species of flowering plant in the pipewort family known by the common names Parker's pipewort and estuary pipewort. It is native to eastern North America, where its distribution spans the coast from Quebec to North Carolina. It is extirpated from New York and Pennsylvania, however. This small aquatic monocotyledonous perennial herb produces narrow, linear, grasslike leaves up to about 9 centimeters long and flowering stems up to 30 centimeters tall, but generally reaching 1 to 20 centimeters. The flowering stem, or scape, is about a millimeter wide or less. It is topped with a grayish, buttonlike inflorescence just a few millimeters wide. This plant is similar to Eriocaulon aquaticum, but smaller. It is monoecious, with male and female flowers on the same plant. Flowering occurs in July through September. This plant grows in coastal habitat types, such as mudflats, estuaries, and marshes, but in freshwater or slightly brackish water. It may be submerged at times......read more on Wikipedia.
