This Hygrophila was named after the Brazilian river Araguaia in trade, however, later on it was identified as the Asian species Hygrophila lancea. Under water it grows lineal reddish-brown leaves with a lighter-coloured central vein. Its stems have a creeping growth habit, ramify well and form low bushes. It needs a good CO2 supply. Trimming the leaves maintains the bushy form. Hygrophila lancea "Araguaia" needs intensive lighting, and in contrast to most other Hygrophila species it is a rather slow grower. Usually it is sold in its emerged form and differs very much from the underwater form, which develops after it has been placed in the aquarium.
