A reply:
"I'm agree with the statement that through images it is difficult to
identify a commercial variety due to presence of number of hybrids and
cultivars of same species or interspecies.


At present there are eight (08) genera and 70 accepted species under family
Nymphaeaceae

*Barclaya *Wallich (02 species)
Euryale Salisbury (01 species)
*Hydrostemma *Wallich (01 species)
*Nuphar *Smith (18 species)
*Nymphaea *Linnaeus (44 species)
*Nymphozanthus *Richard (01 species)
*Ropalon *Rafinesque (01 species)
*Victoria* Lindley (02 species)

Here in the attached weblinks (by Surajit sir) we see subgenera or subgenus
of genus Nymphaea, and the subgenus is one of the possible subdivisions of
a genus (according to International Code of Botanical Nomenclature - ICBN).
Where, it is not mandatory to use subgenus as generic epithet.
Further, more details are available at ICBN, Chapter III, section 3,
article 21.
Since, there are number of cultivars/hybrids under Nymphaea species
(Intersubgeneric
cross - means cross between subgenera/species of different subgenera (5
listed) of same genus as in attached .pdf file). So, it is wrong to say
that there are other genera look like Nymphaea, and we can say that
generated thing is a hybrid of different subgenera of same genus unless it
is authenticated as new species by ICBN.

Kind regards,

Varun"


Thanks, Varun ji.
