CU Museum of Natural History presents RARE II, an exhibition of contemporary botanical illustrations featuring globally imperiled plants found in Colorado. The 40 original works of art are rendered by the Rocky Mountain Society of Botanical Artists in watercolor, colored pencil, acrylic, oil, pastel, print and mixed media and meet criteria for scientific accuracy, aesthetics, and technical mastery. Exhibit is free and open daily through March 20, 2017 in the BioLounge.
