That tongue is a high-performance tool : its edges roll up to form two tiny tubes for sipping, and its frayed tip forms a perfect attachment spot for the pollen sacs.

When the plant's pollen sacs break open in the morning, the pollen grains are carried along the stalk, or style, toward the stigma ( the pollen receptor ) by this oozing emulsion.

The flowers, unfortunately, are similar at first glance, with four or five stamens ( short stalks topped with a small pollen sac ) surrounding a single pistil ( a small globular structure containing the ovary ).

The bases of the pollinia then mechanically attach to the insect, so that a pair of pollen sacs can be pulled free when the pollinator flies off, assuming the insect is large enough to produce the necessary pulling force ( if not, the insect may become trapped and die ).
