Halodule pinifolia is a species of seagrass in the genus Halodule. It is found in shallow sea waters in the western Pacific ocean.[2]
Distribution and habitat
Halodule pinifolia is a common seagrass in Asian tropical coasts. It forms homogenous patches in intertidal zones, or it is occasionally intermixed with other seagrasses such as Halodule uninervis.[3] Halodule pinifolia grows in sandy or muddy sand substrates from upper littoral to subtidal areas. It is ephemeral with rapid turn-over and high seed set and is well adapted to high levels of disturbance. This species is can grow rapidly and is a fast coloniser, often heavily epiphytised. Halodule pinifolia has been studied at Laucala Bay on the island of Viti Levu, Fiji.[4]
Description
In Fiji, Halodule pinifolia was observed to undergo hydrophilous pollination, in which pollen disperses directly on the water surface. Prior to dehiscence[4] during low spring tides, the long filaments bearing the anthers become erect[5] above the mass of filiform leaves. Once exposed to air, the 32 mm long filaments burst, releasing a cotton-like mass of filiform pollen which assemble into floating rafts on the water surface.[5][4] Halodule pinifolia was found to be strictly dioecious.[4]
Ecology
This species is known to be hybridized to Halodule uninervis in Okinawa, Japan.[2]
