Za odredjivanje vrste biljaka Cryptocoryne roda potrebno je da se ima uvid u cvet biljke i bez toga je besmisleno da se upustamo u odredjivanje vrste. Listovi odnosno izgled biljke nam ne pruzaju dovoljno pokazatelja za uspesan rad u odredjivanju vrste biljka roda Cryptocoryne.

Brojevi u zagradama referisu ka alternativnom izboru ili drugom delu izraza datog kljuca.
