The images shown are primarily from the Denver Botanical Gardens herbarium plant. Pollen images taken on an Unitron TCS Pro 500 at 400x  (unless noted). The webpage is not exhaustive and only represents common types represented in lake sediments and bee products examined in the Paleoecology, Palynology and Climate Change Laboratory. Pollen-types are identified down to their lowest taxonomic level possible starting with family. Follow the tabs to lower taxonomic levels. The morphological characteristics of the pollen grain are described based on shape, aperture type(s), wall structure, surface sculpturing, and size. Were possible a link to an online pollen database with more information is also provided.
