Marsilea Condensata
''Marsilea'' is a genus of approximately 65 species of Aquatic plant, aquatic ferns of the family Marsileaceae. The name honours Italian naturalist Luigi Ferdinando Marsili (1656–1730). These small plants are of unusual appearance and do not resemble common ferns. Common names include water clover and four-leaf clover because of the long-stalked leaves have four clover-like lobes and are either present above water or submerged. It is worth clarifying that these plants are not clovers. The sporocarp (ferns), sporocarps of some Australian species are very drought-resistant, surviving up to 100 years in dry conditions. On wetting, the gelatinous interior of the sporocarp swells, splitting it and releasing a worm-like mass that carries Sorus, sori, eventually leading to germination of spores and fertilization. Uses As food Sporocarps of some Australian species such as ''Marsilea drummondii'' are edible and have been eaten by Aborigines and early white settlers, who knew it unde ...

Marsilea Villosa
''Marsilea villosa'', the ihiihi ( Hawaiian) or villous waterclover ( English), is a species of fern that is endemic to the islands of Oahu, Molokai and Niihau in Hawaii. It is found exclusively in areas that experience periodic flooding and become ephemeral pools within low elevation dry forests and shrublands. Standing water allows the sporocarp to open and release spores. It also enables the resulting sperm to swim toward and fertilize female ova. For new plants to become established, the waters must subside. Sporocarps only form once the soil has dried to a certain level. Like other species in its genus, the leaves of ''M. villosa'' resemble those of a four-leaf clover. Conservation Fewer than 2,000 individual plants exist in four remaining populations. The plant was federally listed as an endangered species in 1992. References External links villosa ''Villosa'' is a genus of freshwater mussels, aquatic bivalve molluscs in the family Unionidae.
