Aquatic fern bearing 4 parted leaf resembling 'Four-leaf clover' (Trifolium).Leaves floating in deep water or erect in shallow water or on land.

The four-leaf clover is a rare variation of the common three-leaf clover that has four leaflets instead of three. According to traditional sayings, such clovers bring good luck , [ 1 ] a belief that dates back to at least the 17th century.
The group is commonly known as the "pepperwort family" or as the "water-clover family" because the leaves of the genus Marsilea superficially resemble the leaves of a four-leaf clover. In all, the family contains three genera and 50 to 80 species with most of those belonging to Marsilea. [1] [2]
The leaves are trifoliate (rarely, they have four or more leaflets; the more leaflets the leaf has, the rarer it is; see four-leaf clover), with stipules adnate to the leaf-stalk, and heads or dense spikes of small red, purple, white, or yellow flowers; the small, few-seeded pods are enclosed in the calyx. [3]
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.
