Limnophila sessiliflora, known as dwarf ambulia, ambulis, and Asian marshweed is a flowering plant in the family Plantaginaceae, mostly found in southeast Asia. This species appears superficially similar to Cabomba caroliniana, yet it has leaves formed in whorls, about 3 cm in diameter. Any confusion is likely due to the leaves being pinnate and bright green in colour. Under strong artificial light or sunlight, the leaves take on a reddish, 'stresses' hue, as do many plant species. When the plant has received enough light for the day, the whorls of leaves will often close, and the entire plant will "sleep". This plant can, eventually, reach over 40 cm in height, often growing emergent (out of the water's surface), where sunlight and carbon dioxide is far more available to the plant. The submersed leaves are very different from the emerged leaves, due to lower light penetration through the water, often more dark green, and more or less 'Lance'-shaped.
