"enhalus" is large seagrass native to coastal waters of the tropical indian and western pacific oceans. it is the only species of seagrass that does aerial surface pollination in which the pollen and the styles remain dry. "enhalus" is surface pollinated with male flowers that detach from the plant to float on the surface until they reach a female flower where pollination can occur. enhalus acoroides is considered a slow-growing, "climax" species.
