Finely feathery, often whorled leaves on aquatic and marsh herbs, with submerged leaves typically much more finely divided than any emergent ones on the same plant; tiny, often petal-less flowers form along a spike that rises just above the water.
Many species show striking leaf dimorphism — the same plant grows finely feathered, thread-like leaves underwater and broader, simpler leaves in air, an adaptation to two very different light and support conditions.
