Nymphaea dimorpha

This species exhibits two distinctive growth forms. The submerged growth form has very thin foliage with short petioles. The emergent form has floating leaves with longer petioles.

It grows in pools of water among slowly flowing streams. The pools, which are darkened with organic material, are shaded by the canopy of tropical forest.

Cleistogamy occurs in this species. It can produce flowers, which never open, but self-fertilise and never reach the water surface.

It is easily cultivated and suitable for low-light conditions. In cultivation it may grow four times larger than plants observed in their natural habitat. This is due to better fertilisation. It is very sensitive to cold temperatures. It is used in hybridisation to create new smaller waterlily cultivars.

This species was first described as Nymphaea minuta K.C.Landon, R.A.Edwards & Nozaic in 2006. Later, it was discovered that this was a Nomen illegitimum, as the name was preoccupied by the French fossil waterlily Nymphaea minuta Saporta described in 1891. Therefore, the new name Nymphaea dimorpha I.M.Turner was chosen in 2014.
