  • Numerical method trumps descriptive approach to classifying pollen grains

    A team of researchers at the University of Illinois used scanning electron microscopy to produce detailed images of whole pollen grains like that of the Poa australis species shown here, left. A computer program then used the high-resolution grain surface patterns, right, to classify and identify the species of grass pollen.
