Even in absence of pollinating agents, seed setting is assured in Commelina, which is also called as 'Asiatic dayflower'. They lack nectar, they offer only pollen as a reward to their visitors. To attract pollinators, the plant has three types of brightly coloured floral organs: the large blue petals, fertile yellow anthers and infertile yellow antherodes that lack pollen.

Bombax, Butea, and Bauhinia are all typically pollinated by birds (ornithophily).

Hypohydrogamous pollination occurs underwater, which is characteristic of Vallisneria (though it is often cited as epihydrogamous, some sources classify it under underwater mechanisms).
