Definatley not L.Aromatica,
It is sometimes reffered to as "rice paddy"
If you ask me it looks like a ludwigia sp. going by the leaves although the red stem throws me. It may not be aquatic, or it my be in its emersed form. I would plant it and see what happens with regards to new growth.
That picture is not L.aromatica it is L.hippuroides. I can email pictures to you from book if Ineed to. Look in The Aquarium Plant Handbook with foreword by Takashi Amano!!
