"enhalus acoroides" massive rhizomes (1.5 cm in diameter) help it stay anchored in soft mud substrates, withstanding wave action and tidal currents. it has long strap like leaves (30–150 cm) which make up a significant volume of total plant biomass of shallow water seagrass beds, because of the large structure of the leaves and where they are in the water column, they provide greater surfaces for epibiont organisms to inhabit. fruit are round and large (4–6 cm in diameter) with dark, ribbed skin and 6-7 white seeds. the male plant bears a single pedunculate inflorescence or stem containing clusters of flowers, each is highly reduced in form to a small free floating device. female enhalus acoroides bears only a single inflorescence, but the peduncle of a female flower is much longer.
