Term:
Secondary pollen presentation
Secondary pollen presentation
Definition:
The presentation of pollen to the pollinator in a place other than the anther.
The presentation of pollen to the pollinator in a place other than the anther.
Notes:
In general, it is believed that neotropical Lecythidaceae do not have secondary pollen presentation but we have sometimes observed that pollen falls onto the inner part of the first coil of an androecial hood and, thus, can be rubbed onto the ventral surface of a pollinator, generally bees, while they are taking nectar from the nectar chamber at the apex of the coils. If this hypothesis is correct, then pollen from the vestigial stamens of androecial hood would be placed on the ventral surface and what is left in the anthers of the staminal ring would be placed on the dorsal surface of the pollinators.
