Free-floating aquatic; roots 0.
Stem: horizontal.
Leaf: in groups of 3 along stem, each group of 2 floating leaves, 1 submersed; floating leaves simple, ± sessile or short-petioled, generally ovate to cordate, entire, notched at tip or not, green, hairy, hairs water-repellent on upper face; submersed leaf dissected, root-like, generally petioled, ± white, hairy.
Sporangia: in ± spheric, indehiscent cases of 2 kinds, submersed, on axes in chain-like arrangements or on leaves.
Male sporangium case: few to many; sporangia many per case; spores 32 or 64 per sporangium, spheric, in hard mass.
Female sporangium case: 1–few, basal; sporangia few per case; spore 1 per sporangium, spheric.
1 genus, ± 10 species: ± worldwide, generally tropics. Closest relatives of Azollaceae. In CA, probably all are escapes from cultivation, aquaria, reproducing vegetatively (fertile material documented in CA only for Salvinia minima). —Scientific Editor: Thomas J. Rosatti.
