A total of nine species belonging to five genera from two families of seagrasses was collected from the three coastal regions of Myanmar. These are Cymodocea rotundata, C. serrulata, Halodule pinifolia, H. uninervis, Syringodium isotoefolium, Enhalus acoroides, Halophila beccarii, H. decipiens and H. ovalis. Due to turbid water by enormous sediment discharge of two greatest rivers, the Ayeyarwady and the Thanlwin, the subtidal vegetation of seagrasses is totally absent in the Ayeyarwady Delta and the Gulf of Mottama (Martaban) Coastal Region. The family Hydrocharitaceae represents the most dominant genera of seagrasses in both the Rakhine and the Tanintharyi Coastal Regions. However, the family Cymodoceaceae occurs mainly in the Rakhine Coastal Region,except for Cymodocea rotundata, which is unique to the Tanintharyi Coastal Region. In addition, the phytogeographic distribution and conservation plans of seagrasses of Myanmar have been briefly described.
