Phylogeny, Classification and Floral Evolution of Water Lilies (Nymphaeaceae; Nymphaeales): While the non-flowering plant pollen corresponded to different species of cycads, pollen from flowering plants belonged to a newly described species of water lilies (Fig. The plant goes through an annual dormancy period before producing more leaves that increase in size before flowering again. The leftover of internal pressure is embodied by the constant streams of bubbles that outbreak when rising leaves are ruptured in the spring. There are a few different species of insects who perform pollination for water lilies, including beetles, honeybees, bumble bees, carpenter bees, and sweat bees; not all of the pollinators are able to represented in the Museum exhibition, but the ones found locally most often are featured. Pollination takes place at night when the white flowers open, releasing their aromatic fragrance. Borsch T, Löhne C, Wiersema J (2008) Phylogeny and evolutionary patterns in Nymphaeales: integrating genes, genomes and morphology. Pollination, transfer of pollen grains from the stamens, the flower parts that produce them, to the ovule-bearing organs or to the ovules (seed precursors) themselves. The Victoria amazonica has very large leaves, up to 3 m (10 ft) in diameter, that float on the water's surface on a submerged stalk, 7–8 m (23–26 ft) in length.

Filaments are distinct, free or adnate to petaloid staminodes, slender and well differentiated from anthers to laminar and poorly differentiated from anthers; pollen grains usually monosulcate or lacking apertures. Each pollen grain is haploid: it has half of the DNA (genetic information) that is needed to make a new plant. Genera with more floral parts, Nuphar, Nymphaea, Victoria, have a beetle pollination syndrome, while genera with fewer parts are pollinated by flies or bees, or are self- or wind-pollinated.
