Under the magnification of a dissecting microscope, pollinia were removed from a donor flower by grasping the corpusculum with small forceps.
Pollinia removal was scored by noting the number of corpuscula missing from each flower (a corpusculum is the black structure that connects paired pollinia; it is readily visible in the flower prior to removal).
A pollinarium is removed from the flower when an insect body part catches in the groove of the corpusculum (Wyatt 1978).
