Many aquatic (water dwelling) and some terrestrial (land dwelling) species use hydrochory, or seed dispersal through water. Seeds can travel for extremely long distances, depending on the specific mode of water dispersal; this especially applies to fruits which are waterproof and float on water. The water lily is an example of such a plant.
Seed dispersal is facilitated by the semi-hydrophobia of seeds, which causes them to float on the water's surface until disturbed. [14] Seeds are suited to adhering to surfaces such as the flanks, folds of skin on digit webs, and the short feathers on the heads of waterfowl, which are hydrophobic. [14]
[7] [14] Dispersal over longer distances in water is facilitated through fish which like to feed on the seeds of N. tetragona [14], overland via waterbirds, or dispersed by humans. [13] The establishment of the seed in the appropriate ecological conditions for N. tetragona to thrive and reproduce is considered to be more important than ...
Plants of the genus are known commonly as water lilies, [3] [5] or waterlilies in the United Kingdom. The genus name is from the Greek νυμφαία, nymphaia and the Latin nymphaea , which means "water lily" and were inspired by the nymphs of Greek and Latin mythology .

The nocturnal flowers float on the water surface. [2] The flowers have glabrous, non-brittle green peduncles with 5-6 primary, central air canals and 10-12 secondary, smaller, peripheral canals. [4] The flowers have uniformly green, 3-6 cm long and 1-3 cm wide, oblong-ovate sepals with an slightly rounded or acute apex. [5]
