Very small amounts of pollen was collected.

The small amounts of pollen and nectar could be due to the freshness of the cuttings being unknown. Also, the flowers used in this experiment had straight stigmas and dried anthers, so considering the lifecycle of the grevilea flower, it is likely the flowers had past their pollen release stage and was in the stage for pollination, which explains why there was minimal pollen collected.
