Die Art wird als rigens-curvans-Hybrid charakterisiert.

Der rigens-Komplex erzeugt nur defekte Pollen ( aber funktionsfähige Eizellen ), der curvans-Komplex einen funktionslosen Embryosack.

Deshalb sind nur die Kombinationen rigens ( weiblich ) x curvans ( männlich ) lebensfähig.

The situation is similar in Oenothera muricata : the species is characterized as a rigens-curvans hybrid.

The rigens complex results in defect pollen ( and fully functional egg cells ), the curvans complex in an embryo sac that has lost its function.

Therefore, only the combination rigens ( female ) x curvans ( male ) can survive.
