4.3.1 Taxonomy of Salvina molesta
Domain: Eukaryota.
Kingdom: Plantae
Subkingdom: Tracheobionta
Phylum: Pteridophyta
Class: Liliopsida
Order: Hydropteridales
Family: Salviniaceae
Genera: Salvinia
Species: Salvina molesta
Common names: Giant Salvinia, Karibaweed, water moss, water fern,
Australianazolla, water spangles, African pyle.
Habitat: The habitat of S. molesta can be either still or slow flowing water such as
lakes and dams.
4.4 Subspecies of Salvina molesta
There are 12 main subspecies in Salvinia molesta. They are Salvinia natan, Salvinia
oblongifolia, Salvinia cucullata,Salvinia biloba Radii, Salvinia herzogii, Salvinia
auriculata, Salvinia minima Baker, Salvinia radula, Salvinia sprucei, S. martynii.
Spruce, S. hastata Desv.
4.5 Phytoremediation Process of Salvina molesta Against
Heavy Metals
Salvina molesta can perform phytoremediation of heavy metals in the aquatic
ecosystem due to its higher growth rate and capable of collecting nutrients from
the source. S. molesta can accumulate toxic metals such as lead, cadmium, and
copper (Mitchel 1972; Hariyadi et al. 2013). The species of Salvinia performs an
efficient rhizofiltration method to precipitate toxic metals from the contaminated
water. They are hyperaccumulators of heavy and toxic metals naturally. Therefore
they could be used in the phytoremediation process of a polluted water body.
Many kinds of research have studied the efficiency of Salvina molesta in
phytoremediation of wastewater. S. molesta removes phosphorous and heavy metals
like Cd, Cu, Ni, Zn, Fe, and Pb from the wastewater. This treated water can be used
for irrigation, gardening, cleaning, and washing and the plant can be helpful to
recover the accumulated metals for commercial use (George and Gabriel 2017)
(Fig. 16.3).
