Stamens enclosed by petals in Berchemia (Rhamnaceae): a unique mechanism for pollen presentation

Stamens enclosed by petals in Berchemia (Rhamnaceae): a unique mechanism for pollen presentation

IntroductionPollen is usually presented by the anthers after maturity. However, in some plants, pollen is presented to pollinators on other floral structures (other than the anthers), or via particular expulsion mechanisms, resulting in secondary pollen presentation. The unusual petal morphology in...
