Figure 7 From: Systematics and plastid genome evolution of the cryptically photosynthetic parasitic plant genus Cuscuta(Convolvulaceae) 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.Back to article page
