Which of the following statements is INCORRECT regarding pollination in aquatic plants?

  1. In Vallisneria, female flowers reach the water surface by long stalks.
  2. In seagrasses like Zostera, pollen grains are long, ribbon-like and carried passively inside water.
  3. Water hyacinth and water lily are pollinated underwater by water currents.
  4. Pollination by water is limited to about 30 genera, mostly monocotyledons.
