Ulva australis, the southern sea lettuce, is a species of bright green coloured seaweed in the family Ulvaceae that can be found in waters around Australia and was first described by Swedish botanist Johan Erhard Areschoug. It is an edible green algae, although sometimes designated as a seaweed. General characteristics of Ulva australis include a smooth surface, distromatic blades, lobed fronds, and thallus color from dark green to light grass green. It can be either free floating or attached by a single holdfast. Its cells appear to be irregularly arranged, have rounded edges, and have shapes such as rectilinear, square, and pentagonal. It has been researched for a number of scientific properties in distinct fields such as environmental protection, medicine, and pharmacology. Ulva rigida has sometimes been confused with this species.
