Halophila
''Halophila'' is a genus of seagrasses in the family '' Hydrocharitaceae'', the tape-grasses. It was described as a genus in 1806. The number of its contained species, and its own placement in the order Alismatales, has evolved. Description These oceanic herbs grow underwater and have creeping stoloniferous stems and leafy nodes. Unlike other seagrasses, the leaves of some species of ''Halophila'' do not have basal sheaths (i.e. the bases of the leaves do not wrap around the stem to form a sheath). The flowers are unisexual. The male flowers are borne on stems. The parts occur in multiples of three along a single row. The female flowers do not have stalks. They are divided into three segments. The single chambered ovary has a long beak. The three style are long and simple. The ovules are attached on top of three placentas. The fruit is included in the bract surrounding the inflorescence (the spathe) and crowned by a beak. They have many seeds and thick embryos. Distributio ...

Halophila Decipiens
''Halophila decipiens'', commonly known as Caribbean seagrass or paddle grass, is a seagrass in the family Hydrocharitaceae. It grows underwater on sandy or muddy sea floors in shallow parts of tropical seas. Description '' Halophila'' is the only genus of seagrass that lacks basal sheaths on the leaf stems. ''Halophila decipiens'' has thin rhizomes that run along near the surface of sand or mud, with a root at each node to anchor the plant in place. The almost stemless leaves grow in pairs from the nodes with a pair of scales at their base. The leaves are paddle-shaped and have a finely serrated margin and are up to long and wide. Male and female flowers are found on the same spathe and a female flower can produce about 30 seeds. Flowering seems to be stimulated by a rise in water temperature above a certain threshold rather than day length. The plant is an annual.

Halophila Engelmannii
''Halophila engelmannii'' is a species of seagrass in the Hydrocharitaceae family. It is referred to by the common names star grass and Engelmann's seagrass and grows underwater on shallow sandy or muddy sea floors. It is native to the Bahamas, the Cayman Islands, Costa Rica, Cuba, the Gulf Coast of the United States, the Gulf Coast of Mexico, Puerto Rico, and Trinidad and Tobago. 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. Distribution ''Halophila engelmannii'' is found on the coasts of Florida, Texas, the Bahama ...
