Abstract

Maize (Zea mays subsp. mays) dominates the record of prehistoric agriculture in the Neotropics. Nonetheless, many significant questions of Zea systematics and evolution persist. Palynology provides a record central to addressing those questions, but determining pollen grain diameter remains a significant method- ological issue: diameter is a key characteristic in identification, and diameter seems to be space-time dependent - the latter phenomenon but little understood. One issue in analyzing diam- eter is the confounding effect of microscope-slide mounting media. This study provides correction factors to normalize diam- eter among silicon oil, glycerine jelly, and acrylic resin (du Pont Elvacite), the last coming into increasing use without previous study of its effect on pollen grain size.
