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). Larger fragments, e.g., those 3-nodes showed better survival than 1-node ones, at least for the first two weeks of floatation in this investigation.

A brief history of the Halophila taxonomic development is presented. Lakkis S, Novel-Lakkis V, 2007. Halophila species (H. ovalis, H. stipulacea, H. spinulosa) had already been described under other genera as Zostera stipulacea [13], Caulinia ovalis and C. spinulosa [14]. Halophila ovalis is a beautiful species of sea grass native to Asia and the South Pacific. Productivity increased from 15 to 20°C by a factor of seven, and a further 30% from 20 to 25°C. This paper describes the biomass, distribution and primary production of this plant in relation to environmental factors.Halophila ovalis occupied 550-600 ha in the lower reaches of the estuary, approximately 20% of the area of the main estuarine basin. The distribution of intertidal seagrass meadows was certainly constrained by the surface water turbidity. Lipkin Y, 1975a. Halophila ovalis in the Tropical Atlantic Ocean ...
