Apalanthe granatensis, an aquatic plant from the South-American tropics, is closely related to the waterweed species from the genera Egeria and Elodea. It has narrow leaves of around 1 mm width and up to around 2 cm in length that grow in whorls of 3 to 7 on the stems. The leaf margin is very finely serrate, in contrast to the rather roughly serrate leaves of Egeria najas and Hydrilla verticillata.

This delicate waterweed-like stem plant was first imported from eastern Brazil by Christel Kasselmann in 1994, and it was successfully cultivated in several botanical gardens over some years. Today it doesn't seem to be in cultivation any more, at least in Europe.
