Riccia fluitans is one of the liverwort genus, an aquatic floating plant. Additionally, it might also have supported further adaptations to different ecological niches. The faster evolution rate might have supported the evolution of its phenotypic plasticity and ability to grow submersed, which is likely rather a secondary adaptation of R. fluitans given the exceptional amphibious lifestyle of R. fluitans within the Riccia genus.

One of the more than 100 species in this genus is the "slender riccia" (Riccia fluitans), which grows on damp soil or, less commonly, floating in ponds, and is sometimes used in aquariums. The conversion of the submerged form of Riccia fluitans to the landform either by transfer to a moist solid surface or by treatment with abscisic acid (ABA), is accompanied by the formation of a set of new polypeptides and concomitant down-regulation of other polypeptides. Four different aquatic plants, the Pteridophyte Lomariopsis lineata and the Bryophytes Fontinalis antipyretica, Riccia fluitans and Taxiphyllum barbieri, were tested for their capacity to absorb the neurotoxin β-N-Methylamino-L-alanine (BMAA) from water and thus their possible applicability in a "Green Liver System". Planting and maintenance. Bryophytes are early diversifying land plants that mark the transition from freshwater to terrestrial ecosystems. Mechanical and anatomical adaptations in terrestrial and aquatic buttercups to their respective environments. The colonization of land by streptophyte algae, ancestors of embryophyte plants, was a fundamental event in the history of life on earth. Aquarium plant from tissue culture in closed cup. Riccia is often used as a ground-covering plant in a tank. Their main purpose will be to further oxygenate the water. Pence (1998) found that ABA was necessary for the cryopreservation of some liverworts such as Riccia fluitans (Figure 7) and Marchantia polymorpha (Figure That much more Riccia fluitans fragments were found at site C than at site B and A is likely related to the shorter distance of site C to two tributaries where it occurs abundantly (Figure 1; Boedeltje et al., 2003).
