A palynological data storage and retrieval system is briefly described. It is currently being applied to 900 records of Formosan pollen grains. First, procedures which were used for encoding the morphological features of a pollen grain are outlined. Next, a storage and retrieval system is discussed, which organizes and updates reference pollen records, catalogs them, and enables retrieval of those stored records which share the same features with an unknown specimen. The whole system has been proved useful and effective. The ways in which ihc variable characters arc treated for the sake of obviating encoding errors arc highlighted.
