Morphology of Halophila ovalis (R.Br.) Hook. f. from Peninsular and East Malaysia

Halophila ovalis plants were collected from six locations with different habitat characteristics; Merambong, lohore ofPeninsular Malaysia (sub-tidal shoal), Teluk Sepinong of Sabah (sub-tidal estuary), Pulau Gaya, Sabah (subtidal degraded coral), Merchang, Terengganu (inter-tidal lagoon), Teluk Ke...
