Microvictoria svitkoana is a fossil species of aquatic plant, which occurred in the Cretaceous period of New Jersey, USA.Gandolfo, M. A., Nixon, K. C., & Crepet, W. L. (2004).

Description
=Generative characteristics=
Taxonomy
=Publication=
It was published by Maria Alejandra Gandolfo, Kevin C. Nixon, and William L. Crepet in 2004.
=Type specimen=
The type specimen was collected in the Old Crossman Clay Pit, Sayreville, New Jersey, USA.
=Position within Nymphaeales=
It is placed in the family Nymphaeaceae. This placement has been questioned by different authors, who believe it may be placed outside of the order Nymphaeales.Friis, E. M., Crane, P. R., & Pedersen, K. R. (2011). [https://books.google.com/books?id=3lk2LcfRFRkC&dq=Microvictoria+svitkoana&pg=PA204 "Early Flowers and angiosperm evolution."] p. 204.

It has been proposed to include it in a newly described family Microvictoriaceae Doweld with a possible affinity to the order Illiciales.Doweld A.B. 2022.
