Clover Grass

Halophila baillonii, commonly known as clover grass or simply Halophila, is a small marine seagrass in the family Hydrocharitaceae, order Alismatales. Despite its vernacular name suggesting a terrestrial grass, it is fully aquatic, inhabiting tropical and subtropical shallow marine waters. H. baillonii grows primarily in the Caribbean Sea and Western Atlantic, occurring across island and coastal areas where warm, shallow, clear water and suitable substrate are available. The species forms low-growing meadows of oval to heart-shaped leaf pairs emerging from creeping rhizomes, reaching only a few centimeters in height. As a seagrass, it occupies a critical ecological role in shallow coastal marine ecosystems, providing habitat and feeding grounds for sea turtles, dugongs, fish, and invertebrates, as well as stabilizing sediments and cycling nutrients. H. baillonii is one of the smaller seagrass species and is found growing on sandy, silty, and sometimes rocky substrates in lagoons, reef flats, and sheltered bays at depths ranging from the intertidal zone to approximately fifteen meters. The species is dioecious — with male and female flowers borne on separate plants — and reproduces both sexually and through vegetative spread. H. baillonii is classified as Vulnerable on the IUCN Red List, with populations threatened by coastal development, water quality degradation, increased turbidity, and climate-related changes including sea temperature rise and ocean acidification, which stress shallow seagrass ecosystems throughout the Caribbean region.
