Identification

| Main identification characters |
Grass like flowering plant with dark green, long, narrow, ribbon shaped leaves 20 - 50 cm in length (exceptionally up to 2m long) with rounded tips.
Leaves shoot from a creeping rhizome that binds the sediment. Leaves and rhizomes contain air spaces, lacunae, that aid bouyancy. Numerous flowers occur on a reproductive shoot similar to those of terrestrial grasses. Forms dense swards in the subtidal, supports a diverse fauna and flora and may act as a nursery for fish and shellfish. |
