Editing Buzz pollination (section)

== Flower morphology ==
Plants that rely on buzz [[pollination]] have a unique [[anther]] shape compared to other flora. In buzz pollinated plants, this process can only happen if pollinators visit the flowers to extract pollen. Only a few insect species are able to pollinate these plants. The flower morphology of buzz pollinated plants is different from that of other flora that do not use this type of pollination. The anthers are completely sealed except for a small pore at the top or have very small slits that open along the sides. The pores and slits are small enough that insects cannot easily enter the anther, but large enough pollen can exit. Because of this shape, they are often referred to as poricidal anthers. These poricidal anthers are only able to release pollen when vibrated at a specific [[frequency]].<ref name=":32">{{cite journal|date=1992|title=Buzz pollination of Orpheum frutescens|journal=Veld & Flora|volume=78|issue=2|pages=36–37|last1=Johnson|first1=S.D.}}</ref> The stigmas of these flowers are often located below the anthers. This is could be an evolutionary strategy to prevent [[Self-pollination|self-fertilization]], also known as selfing, by creating distance between the stigma.<ref name=":32" />
