Scientific Name: Limnophila sessiliflora 
Native to the waterways and marshlands of Southeast Asia, Ambulia has become a very popular bunched plant in the aquarium trade for its delicate lime-green foliage. As they are a marginal aquatic plant, they require reasonably good light quality, or they will drop their lower leaves and become "leggy". The whorls of fine leaves make great protected habitat for fish fry.
