The Atlas of Florida Plants provides a source of information for the distribution of plants within the state and taxonomic information. The leaf has obvious cross veins (4-25) and is held on a long thin stalk. Aims Plants are able to influence their growing environment by changing biotic and abiotic soil conditions. Halophila ovalis internode length was found to increase during the Late-Monsoon each year at reef habitats in the Dry Tropics. Bibliographic References Phylogenetically, Halorhodospira halophilais associated within the gamma subdivision of the phylum Proteobacteria and is known to be phototrophic and Gram-negative.

These soil conditions in turn can influence plant growth conditions, which is called plant–soil feedback. Estimates of meadow characteristics (biomass, branching effort, tagged apices and leaf density) were determined from five replicate samples collected by core (96 mm diameter polycarbonate core inserted 15 cm into the sediment and sieved (2 mm) in the field).
