Abstract
Three species of the genus Aerides Lour namely Aerides ringense Fisher, A. maculosum Lindl. and A. crispum Lindl. were studied in relation to their pollinia under SEM. Viscous hairy structures were observed on the surface of pollinia of all the three species. It appears that the glandular hairs having elasto-viscin might be helping to bind the pollen-grains together and create moisture near the stigmatic surface for the purpose of pollination.
