Marsilea quadrifolia - L.
                 
Common Name Water Clover, European waterclover
Family Marsileaceae
USDA hardiness 4-8
Known Hazards Although we have found no reports of toxicity for this species, a number of ferns contain carcinogens so some caution is advisable[200]. Many ferns also contain thiaminase, an enzyme that robs the body of its vitamin B complex. In small quantities this enzyme will do no harm to people eating an adequate diet that is rich in vitamin B, though large quantities can cause severe health problems. The enzyme is destroyed by heat or thorough drying, so cooking the plant will remove the thiaminase[172].
Habitats Ponds and paddy fields all over Japan[58].

Cultivation details
Requires a permanently moist or wet soil, it can be grown by the side of ponds etc or in the shallow edges of the pond[56]. Thrives in a turfy loam or in peat[1]. Hardy to about -15°c[200]. Members of this genus are rarely if ever troubled by browsing deer[233].
Propagation
Spores. The plant produces sporocarps, these need to be lightly abraded and then immersed in water. The sporocarps will then swell and burst to release the spores. The spores germinate immediately, the highly developed prothallus remains inside the large seed-like spores. The gametophyte generation is completed in 24 hours and the first roots and shoots appear in 2 - 3 days. Mature plants bearing sporocarps can develop in as little as 3 months[200]. Spore germination in the family occurs after rupture of the sporocarp wall allows the sporocarp contents to be hydrated. A gelatinous structure emerges from the sporocarp, breaking it into valves and carrying the sori into the water. Spore germination (gametophyte growth) and fertilization occur immediately[270].

This fern is well known in West Bengal and Bangladesh as "Sushni".It is available in vegetable markets as a leafy green with medicinal properties. The name Sushni in colloquial Bengali means 'dont sleep'as it is eaten cooked, for its soporific effect. Common people use it as it is cheaper and more easily available than prescription drugs.
