Halophila johnsonii, a species on the U.S. Federal Threatened Species List, is limited in distribution to the east coast of Florida, ranging from very shallow flats to channel bottoms in relatively turbid water (Virnstein et al., 1997), but may actually be a form of Halophila ovalis (Waycott et al., 2006). Halophila is a genus of seagrasses in the family Hydrocharitaceae, the tape-grasses.It was described as a genus in 1806. The first description of the species was by Robert Brown as Caulinia ovalis, this was transferred to the genus Halophila by Joseph Dalton Hooker in Flora Tasmaniae (1858). A brief history of the Halophila taxonomic development is presented. Leaves in pairs, subtended by bracts; petiole 1-3 cm long; lamina variable in shape and size, linear to lanceolate or ovate ('racquet-shaped'), 10-15 mm long and 2-8 mm wide, green often with brown transverse lines, apex acute, or rounded, base attenuate or rounded.
