What is Water clover

Water clover,four leaf clover; European waterclover or demjiso (Marsilea quadrifolia) is a summergreen perennial of the genus Marsilea in the family Marsileaceae, and a member of the fern family of water plants. It was originally a weed that grew in paddy fields, but is now listed as an endangered species II (VU) by the Ministry of the Environment. It looks like a dicotyledonous grass, but it is a fern with spore-caps on the stem. It produces green leaves in the summer but dies in the winter. The leaves are quadrupleafed and have no serrations on the leaf margins. Its name comes from the fact that its four leaves resemble the Chinese character for "rice field". Because it is a fern, it does not flower but produces spores, which are then followed by the formation of sporophytes.
