A newly discovered species of lichen — a plant-like growth that looks like moss or a dry leaf — has been named after President Obama. Kerry Knudsen, lichen curator of the University of California, Riverside Herbarium, discovered the species in 2007 while doing a survey for lichen diversity on Santa Rosa Island in California. "I named it Caloplaca obamae to show my appreciation for the president's support of science and science education," he said. "I made the final collections of C. obamae during the suspenseful final weeks of President Obama's campaign for the United States presidency."
