What are the plants that spread their seeds by water?

The plants that spread seeds by water include coconuts, water lilies and so on. When the fruit of the coconut tree is ripe, it will fall from the tree and float away with the sea. When the tide washed it up on the island, new coconut trees will grow on the shore. When the fruit of the water lily is ripe, it will slowly rot in the water, and the seeds covered with a spongy outer seed coat will float and float somewhere else, and finally sink to the bottom to take root and sprout.
