Lomariopsis lineata is a fern from South East Asia whose prothallia (the small, flat, early growth stage) are grown as an aquarium plant, known to aquarists as süsswassertang. Adult plants are large pinnate ferns that grow in humid forest, sometimes on trees or rocks, and are rarely grown as a houseplant.

About

Lomariopsis lineata is a species of fern native to South East Asia. The prothallia of this species (or possibly a closely related species) are commonly cultivated as an aquarium plant, where it is known to aquarists as süsswassertang (German spelling: Süßwassertang). It is often incorrectly spelled "subwassertang" due to the German eszett's similarity to the Latin 'B'. It is also called Loma fern or round pellia.
