Abstract

Summary Results of Reitsma's detailed investigation of Alangium pollen appear to differ markedly from conclusions obtained with other systematic approaches, but the contradictions largely disappear when allowance is made for the occasional independent origin of similar pollen characters in related taxa. Objections are raised to certain points in Reitsma's treatment of the fossil record.
