Close-up of leaves, showing water-repellent trichomes. H. Shoot showing two floating leaves and one submersed and root-like, at each rhizome node. The Salviniaceae consist of floating, aquatic herbs.

This hardy plant propagates quickly and can provide shade to areas of the aquarium, which will encourage more reclusive species to come out of hiding. This is a truly beautiful and very beneficial plant for aquariums with gentle water flow. Care is extremely easy for Water Spangles.
How long do Salvinia roots get?
around 2cm
These hairs help to keep the leaf dry through the magic of surface tension, water droplets roll off the hairs and back into the tank. The roots are pretty short with relatively few branches too, growing up to around 2cm in length, similar to Duckweed.
Why is salvinia a problem for Texas water?
Giant salvinia (Salvinia molesta), a floating fern from southern Brazil, is currently one of the most problematic aquatic plants in Texas. It damages aquatic ecosystems by outgrowing and replacing native plants that provide food and habitat for native animals and waterfowl.

Giant salvinia can be removed by raking or seining it from the pond’s surface, but it will re-establish from any remaining fragments.
Does Salvinia produce seed?
Selaginella and Salvinia are heterosporous plants, which means that they produce two different kinds of spores. Due to this the formation of the seeds or the seed habit is the most significant step towards sexual reproduction and evolution.
How does Salvinia molesta reproduce?
Salvinia can produce by plant parts in two ways: Plant fragments – If a part of the stem containing a node breaks away from the main plant it can grow a new plant. Damaged or dead plant material stimulates bud development. One pair of leaves can start an entire new infestation.

What is the purpose of salvinia?

What are the two types of gametophytes in Salvinia?
Two types of gametophytes may be expected since Salvinia is heterosporous. In both micro and mega gametophytes the development is endosporic. The gametophytes begin their development much earlier to the dehiscence of the sporangium. The megaspore generally floats on the surface of water in a prone position.
