Stamens enclosed by petals in Berchemia (Rhamnaceae): a unique mechanism for pollen presentation [PDF]
Frontiers in Plant ScienceIntroductionPollen 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 ...

Secondary pollen presentation and foral traits of Heliconia psittacorum [PDF]
Ornamental Horticulture, 2018 The secondary presentation of pollen consists of a foral mechanism where the presentation of pollen occurs in other foral structures in addition to the anther, in order to increase the precision of the dispersion of the pollen by the vectors.

SECONDARY POLLEN PRESENTATION, PSYCHOPHILY AND ANEMOCHORY IN Lagascea mollis Cav. (ASTERACEAE)
Biotropia: The Southeast Asian Journal of Tropical Biology, 2017 Information on pollination ecology and seed dispersal aspects is essential to understand sexual reproduction in Lagascea mollis Cav. The study was aimed at providing details of pollen presentation system, pollination syndrome, pollinators and seed ...

A fishing expedition to discover the pollinators of several subtropical Apocynaceae
Applications in Plant Sciences, 2020 Premise Flowers of the Apocynaceae (milkweed family) have complex structures and pollination mechanisms. Pollen removal and deposition in Angadenia, Pentalinon, and Echites are similar, with anthers releasing pollen onto the sterile style head.
