Sri Lanka: östliches Küstengebiet, wenige Fundorte
Under the name "Cryptocoryne nevillii", a relatively small, undemanding Cryptocoryne has been known in the aquarium hobby. Niels Jacobsen proved already in 1976 that this plant does not have anything in common with true C. nevillii but that its correct botanical name is Cryptocoryne willisii. Under the name C. x willisii, a group of natural hybrids is comprised that are found in the central highlands of Sri Lanka. For further detail, please see Cryptocoryne x willisii “nevillii”.
Cryptocoryne parva was also (and sometimes still is) erroneously called "C. nevillii" by hobbyists.
True Cryptocoryne nevillii, however, is a totally different species that only grows in a few locations in the lowlands along the eastern coast of Sri Lanka. It can be discerned from C. x willisii and C. parva amongst others by the form and colour of its inflorescence as well as by the fact that it does naot form runners.
C. nevillii is not available in trade and is said not to be suitable as aquarium plant. This rare species has been cultivated emersed by some hobbyists since 1979.
