''Halophila engelmannii'', commonly known as star grass and Engelmann's seagrass, is a flowering plant, a seagrass in the family Hydrocharitaceae. It grows underwater on sandy or muddy sea floors in shallow parts of the Gulf of Mexico and the Caribbean Sea. ==Description== Halophila is the only genus of seagrass lacking basal sheaths on the leaf stems. Like other seagrasses, ''Halophila engelmannii'' has rhizomes that run along near the surface of sand or mud, with roots at the nodes to anchor them in place. Each leaf stem grows from a node and has a pair of scales halfway up and another pair at the base of the leaf blades. There are 4 to 8 blades on each stem, each of which is up to long and wide. Each blade is oval, has 6 to 8 veins and a finely serrated margin.〔(''Halophila engelmannii'' star grass ) Florida Fish and Wildlife Conservation Commission. Retrieved 2012-01-28.〕
