Monetianthus mirus was a species of fossil plant, which occurred in the early Cretaceous period of Portugal.[1]
Monetianthus mirus had small, bisexual, actinomorphic flowers with 9-10 tepals. The androecium consists of 20 stamens. The pollen grains are monocolpate and reticulate. The gynoecium consists of 12 syncarpous carpels. The ovules are anatropous.
It was published by Else Marie Friis, Kaj Raunsgaard Pedersen, Maria von Balthazar, Guido W. Grimm, and Peter Robert Crane in 2009.
The type specimen was collected in Vale de Agua in western Portugal.
It is placed in the family Nymphaeaceae.[2]
The generic name Monetianthus honours Claude Monet. The specific epithet mirus, from the Latin mirus, means wonderful, remarkable, or extraordinary.
