Giant salvinia is a free-floating aquatic fern whose horizontal stems bear a whorl of three leaves at each node; the submerged lower leaf is brown, finely branched and functions as a root.
The upper surfaces of the green leaves bear rows of coarse white hairs, each dividing into four branches that join at their tips, forming eggbeater-like structures.
