Floral diversity within the genus Cuscuta. Ruler marks to the left are millimeters. Cuscuta chilensis and C. rostrata were unable to produce selfed seed when hand-pollinated, whereas all other species readily produced selfed seed with no assistance. C. coryli flower is rehydrated from an herbarium specimen; all other flowers were collected fresh from the Pennsylvania State University greenhouse.
