The Leek Orchid pollen packet is neatly situated within the column structure and appears to be attached to a spring-loaded strap.  (see photo upper right)

When disturbed, the strap flips the uniquely configured packet forward.  If the pollinia is not removed, the pollen packet remains exposed (still attached to the stipe) above the anther. (see photo lower right)

It is this action that obviously places the pollen packet in a position to be attacked (broken apart) by the various visiting insects. (see photo lower left)
