Microvictoria svitkoana is a fossil species of aquatic plant, which occurred in the Cretaceous period of New Jersey, USA.[1]
Description
[edit]Generative characteristics
[edit]The pedunculate, actinomorphic flowers are 2.3-3.4 mm long, and 1.2-1.6 mm wide. The peduncle is 0.4-1.8 mm long. Both staminoids and fertile stamens are present.[1]
Taxonomy
[edit]Publication
[edit]It was published by Maria Alejandra Gandolfo, Kevin C. Nixon, and William L. Crepet in 2004.[1]
Type specimen
[edit]The type specimen was collected in the Old Crossman Clay Pit, Sayreville, New Jersey, USA.[1]
Position within Nymphaeales
[edit]It is placed in the family Nymphaeaceae.[1] This placement has been questioned by different authors, who believe it may be placed outside of the order Nymphaeales.[2][3]
Etymology
[edit]The generic name Microvictoria expresses an affinity to the extant genus Victoria. The specific epithet svitkoana honours Jennifer L. Svitko,[1] a lab technician of the Cornell University.[4][5]
Ecology
[edit]Pollination
[edit]It was pollinated by insects.[6]
