Abstract
The attachment of pollen grains among themselves, on the loculus wall, and on flower-visiting insects is quite different in entomophilous angiosperms using pollenkitt and those using viscin threads as pollen adhesives. The sticky and viscous pollenkitt makes the pollen grains adhere, while the thin, non-elastic, non-sticky, and flexible viscin fibers fasten them like ropes on insect hairs or bristles. Nectar vomited by honey-bees, sticky stigma secretions or other additional sticky substances further improve the pollen adherence to flower-visiting insects.
